93 <!-- INTRODUCTION -->
94 <h2 id="intro">Introduction</h2>
96 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
97 a single database. To accomplish the latter you'll need a properly set up
98 MySQL user who can read/write only the desired database. It's up to you to
99 look up the appropriate part in the MySQL manual.
100 </p>
102 <h3>Currently phpMyAdmin can:</h3>
104 <ul><li>browse and drop databases, tables, views, fields and indexes</li>
105 <li>create, copy, drop, rename and alter databases, tables, fields and
106 indexes</li>
107 <li>maintenance server, databases and tables, with proposals on server
108 configuration</li>
109 <li>execute, edit and bookmark any
110 <abbr title="structured query language">SQL</abbr>-statement, even
111 batch-queries</li>
112 <li>load text files into tables</li>
113 <li>create<a href="#footnote_1"><sup>1</sup></a> and read dumps of tables

150 <h4>A word about users:</h4>
151 <p> Many people have difficulty
152 understanding the concept of user management with regards to phpMyAdmin. When
153 a user logs in to phpMyAdmin, that username and password are passed directly
154 to MySQL. phpMyAdmin does no account management on its own (other than
155 allowing one to manipulate the MySQL user account information); all users
156 must be valid MySQL users.</p>
158 <p class="footnote" id="footnote_1">
159 <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
160 dumps and <abbr title="comma separated values">CSV</abbr> exports if you use
161 PHP with Zlib support (<tt>--with-zlib</tt>) and/or Bzip2 support
162 (<tt>--with-bz2</tt>). Proper support may also need changes in
163 <tt>php.ini</tt>.</p>

173 </ol>
175 <p class="important">
176 phpMyAdmin does not apply any special security methods to the MySQL database
177 server. It is still the system administrator's job to grant permissions on
178 the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
179 be used for this.
180 </p>
182 <p class="important">
183 Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
184 if you are on a <acronym title="Apple Macintosh">Mac</acronym>
185 <abbr title="operating system">OS</abbr> version before
186 <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
187 <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
188 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
189 before uploading them to your server, as PHP seems not to like
190 <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
191 (&quot;<tt>\r</tt>&quot;).</p>
193 <h3 id="quick_install">Quick Install</h3>
194 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
195 Downloads page. Some kits contain only the English messages,
196 others contain all languages in UTF-8 format (this should be fine
197 in most situations), others contain all
198 languages and all character sets. We'll assume you chose a kit whose
199 name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
200 </li>
201 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
202 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
203 document root. If you don't have direct access to your document root,
204 put the files in a directory on your local machine, and, after step 4,
205 transfer the directory on your web server using, for example, ftp.</li>
206 <li>Ensure that all the scripts have the appropriate owner (if PHP is
207 running in safe mode, having some scripts with an owner different
208 from the owner of other scripts will be a
209 problem). See <a href="#faq4_2">
210 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
211 <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
212 1.26</a> for suggestions.</li>
213 <li>Now you must configure your installation. There are two methods that
214 can be used. Traditionally, users have hand-edited a copy of
215 <tt>config.inc.php</tt>, but now a wizard-style setup script is
216 provided for those who prefer a graphical installation. Creating a
217 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
218 <ul><li>To manually create the file, simply use your text editor to
219 create the file <tt>config.inc.php</tt> (you can copy
220 <tt>config.sample.inc.php</tt> to get minimal configuration
221 file) in the main (top-level) phpMyAdmin directory (the one
222 that contains <tt>index.php</tt>). phpMyAdmin first loads
223 <tt>libraries/config.default.php</tt> and then overrides those
224 values with anything found in <tt>config.inc.php</tt>. If the
225 default value is okay for a particular setting, there is no
226 need to include it in <tt>config.inc.php</tt>. You'll need a
227 few directives to get going, a simple configuration may look
228 like this:
229 <pre>
230 &lt;?php
231 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
233 $i=0;
234 $i++;
235 $cfg['Servers'][$i]['auth_type'] = 'cookie';
236 ?&gt;
237 </pre>
238 Or, if you prefer to not be prompted every time you log in:
239 <pre>
240 &lt;?php
242 $i=0;
243 $i++;
244 $cfg['Servers'][$i]['user'] = 'root';
245 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
246 $cfg['Servers'][$i]['auth_type'] = 'config';
247 ?&gt;
248 </pre>
249 For a full explanation of possible configuration values, see the
250 <a href="#config">Configuration Section</a> of this document.</li>
251 <li id="setup_script">Instead of manually editing
252 <tt>config.inc.php</tt>, you can use the
253 <a href="setup/">Setup Script</a>. First you must
254 manually create a folder <tt>config</tt> in the phpMyAdmin
255 directory. This is a security measure. On a Linux/Unix system you
256 can use the following commands:
257 <pre>
258 cd phpMyAdmin
259 mkdir config # create directory for saving
260 chmod o+rw config # give it world writable permissions
261 </pre>
262 And to edit an existing configuration, copy it over first:
263 <pre>
264 cp config.inc.php config/ # copy current configuration for editing
265 chmod o+w config/config.inc.php # give it world writable permissions
266 </pre>
267 On other platforms, simply create the folder and ensure that your
268 web server has read and write access to it. <a href="#faq1_26">FAQ
269 1.26</a> can help with this.<br /><br />
271 Next, open <tt><a href="setup/">setup/</a>
272 </tt>in your browser. Note that <strong>changes are not saved to
273 disk until explicitly choose <tt>Save</tt></strong> from the
274 <i>Configuration</i> area of the screen. Normally the script saves
275 the new config.inc.php to the <tt>config/</tt> directory, but if
276 the webserver does not have the proper permissions you may see the
277 error "Cannot load or save configuration." Ensure that the <tt>
278 config/</tt> directory exists and has the proper permissions -
279 or use the <tt>Download</tt> link to save the config file locally
280 and upload (via FTP or some similar means) to the proper location.<br /><br />
282 Once the file has been saved, it must be moved out of the <tt>
283 config/</tt> directory and the permissions must be reset, again
284 as a security measure:
285 <pre>
286 mv config/config.inc.php . # move file to current directory
287 chmod o-rw config.inc.php # remove world read and write permissions
288 rm -rf config # remove not needed directory
289 </pre>
290 Now the file is ready to be used. You can choose to review or edit
291 the file with your favorite editor, if you prefer to set some
292 advanced options which the setup script does not provide.</li></ul></li>
293 <li>If you are using the
294 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
295 protect the phpMyAdmin installation directory because using
296 config does not require a user to
297 enter a password to access the phpMyAdmin installation. Use of an alternate
298 authentication method is recommended, for example with
299 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
300 <tt>auth_type</tt> cookie or http. See the
301 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
302 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
303 information, especially <a href="#faq4_4">
304 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
305 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
306 in your browser. phpMyAdmin should now display a welcome screen
307 and your databases, or a login dialog if using
308 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
309 authentication mode.</li>
310 <li>You should deny access to the <tt>./libraries</tt> and
311 <tt>./setup/lib</tt> subfolders in your webserver configuration. For
312 Apache you can use supplied .htaccess file in that folder, for other
313 webservers, you should configure this yourself. Such configuration
314 prevents from possible path exposure and cross side scripting
315 vulnerabilities that might happen to be found in that code.</li>
316 <li>
317 It is generally good idea to protect public phpMyAdmin installation
318 against access by robots as they usually can not do anything good
319 there. You can do this using <code>robots.txt</code> file in root of
320 your webserver or limit access by web server configuration. You can
321 find example <code>.htaccess</code> file which can help you achieve
322 this in <code>contrib</code> directory in phpMyAdmin.
323 </li>
324 </ol>
326 <h3 id="linked-tables">Linked-tables infrastructure</h3>
328 <p> For a whole set of new features (bookmarks, comments,
329 <abbr title="structured query language">SQL</abbr>-history,
330 tracking mechanism,
331 <abbr title="Portable Document Format">PDF</abbr>-generation, field contents
332 transformation, etc.) you need to create a set of special tables. Those
333 tables can be located in your own database, or in a central database for a
334 multi-user installation (this database would then be accessed by the
335 controluser, so no other user should have rights to it).</p>
337 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
338 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
339 special attention to <a href="#faq1_23">
340 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
342 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
343 or newer, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>.</p>
345 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
346 that you may need special (administrator) privileges to create the database
347 and tables, and that the script may need some tuning, depending on the
348 database name.</p>
350 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
351 should specify the table names in your <i>./config.inc.php</i> file. The
352 directives used for that can be found in the <a href="#config">Configuration
353 section</a>. You will also need to have a controluser with the proper rights
354 to those tables (see section <a href="#authentication_modes">Using
355 authentication modes</a> below).</p>
357 <h3 id="upgrading">Upgrading from an older version</h3>
359 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
360 unpacked one. Configuration files from old versions may
361 require some tweaking as some options have been changed or removed; in
362 particular, the definition of <tt>$cfg['AttributeTypes']</tt> has changed
363 so you better remove it from your file and just use the default one.
364 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
365 statement that you might find near the end of your configuration file.</p>
367 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
368 over <tt>config.inc.php</tt> because the default configuration file
369 is version-specific.</p>
371 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
372 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
373 you should run the SQL script found in
374 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
376 <h3 id="authentication_modes">Using authentication modes</h3>
378 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
379 authentication modes are recommended in a <b>multi-user environment</b>
380 where you want to give users access to their own database and don't want
381 them to play around with others.<br />
382 Nevertheless be aware that MS Internet Explorer seems to be really buggy
383 about cookies, at least till version 6, and PHP 4.1.1 is also a bit buggy
384 in this area!<br />
385 Even in a <b>single-user environment</b>, you might prefer to use
386 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
387 that your user/password pair are not in clear in the configuration file.
388 </li>
390 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
391 authentication modes are more secure: the MySQL login information does
392 not need to be set in the phpMyAdmin configuration file (except possibly
393 for the <a href="#controluser">controluser</a>).<br />
394 However, keep in mind that the password travels in plain text, unless
395 you are using the HTTPS protocol.<br />
396 In cookie mode, the password is stored, encrypted with the blowfish
397 algorithm, in a temporary cookie.</li>
399 <li>Note: starting with phpMyAdmin 2.6.1, this section is only applicable if
400 your MySQL server is running with <tt>--skip-show-database</tt>.<br /><br />
402 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
403 modes, phpMyAdmin needs a controluser that has <b>only</b> the
404 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
405 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
406 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
407 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
408 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
409 file under the
410 <tt><a href="#cfg_Servers_controluser" class="configrule">
411 $cfg['Servers'][$i]['controluser']</a></tt> and
412 <tt><a href="#cfg_Servers_controlpass" class="configrule">
413 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
414 The following example assumes you want to use <tt>pma</tt> as the
415 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
416 only an example: use something else in your file!</b> Input these
417 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
418 client.<br />
419 Of course you have to replace <tt>localhost</tt> with the webserver's host
420 if it's not the same as the MySQL server's one.
422 <pre>
423 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
424 GRANT SELECT (
425 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
426 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
427 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
428 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
429 Execute_priv, Repl_slave_priv, Repl_client_priv
430 ) ON mysql.user TO 'pma'@'localhost';
431 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
432 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
433 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
434 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
436 If you want to use the many new relation and bookmark features:
438 <pre>
439 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
440 </pre>
442 (this of course requires that your <a href="#linked-tables">linked-tables
443 infrastructure</a> be set up).<br /></li>
445 <li>Then each of the <i>true</i> users should be granted a set of privileges
446 on a set of particular databases. Normally you shouldn't give global
447 privileges to an ordinary user, unless you understand the impact of those
448 privileges (for example, you are creating a superuser).<br />
449 For example, to grant the user <i>real_user</i> with all privileges on
450 the database <i>user_base</i>:<br />
452 <pre>
453 GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';

458 With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
459 authentication mode, you don't need to fill the user/password fields
460 inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
461 array.</li>
462 </ul>
464 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>
466 <ul><li>Uses <abbr title="HyperText Transfer Protocol">HTTP</abbr> Basic authentication
467 method and allows you to log in as any valid MySQL user.</li>

479 using the <i>.htaccess</i> mechanism along with
480 '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication
481 mode.</li>
482 </ul>
484 <h4>'cookie' authentication mode</h4>
486 <ul><li>You can use this method as a replacement for the
487 <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
488 (for example, if you're running
489 <abbr title="Internet Information Services">IIS</abbr>).</li>
490 <li>Obviously, the user must enable cookies in the browser, but this is
491 now a requirement for all authentication modes.</li>
492 <li>With this mode, the user can truly log out of phpMyAdmin and log in back
493 with the same username.</li>
494 <li>If you want to log in to arbitrary server see
495 <a href="#AllowArbitraryServer" class="configrule">
496 $cfg['AllowArbitraryServer']</a> directive.</li>
497 <li>As mentioned in the <a href="#require">requirements</a> section, having
498 the <tt>mcrypt</tt> extension will speed up access considerably, but is
499 not required.</li>
500 </ul>
502 <h4>'signon' authentication mode</h4>
504 <ul><li>This mode is a convenient way of using credentials from another
505 application to authenticate to phpMyAdmin.</li>
506 <li>The other application has to store login information into
507 session data.</li>
508 <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
509 section.</li>
510 </ul>
511 <h4>'config' authentication mode</h4>
513 <ul><li>This mode is the less secure one because it requires you to fill the
514 <a href="#servers_user" class="configrule">
515 $cfg['Servers'][$i]['user']</a> and
516 <a href="#servers_user" class="configrule">
517 $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
518 can read your config.inc.php can discover your username and password).
519 <br />
520 But you don't need to setup a &quot;controluser&quot; here: using the
521 <a href="#servers_only_db" class="configrule">
522 $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
523 <li>In the <a href="#faqmultiuser">
524 <abbr title="Internet service provider">ISP</abbr>
525 <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
526 is an entry explaining how to protect your configuration file.</li>
527 <li>For additional security in this mode, you may wish to consider the Host
528 authentication
529 <a href="#servers_allowdeny_order" class="configrule">
530 $cfg['Servers'][$i]['AllowDeny']['order']</a> and
531 <a href="#servers_allowdeny_rules" class="configrule">
532 $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
533 directives.</li>
534 <li>Unlike cookie and http, does not require a user to log in when first
535 loading the phpMyAdmin site. This is by design but could allow any
536 user to access your installation. Use of some restriction method is
537 suggested, perhaps a <a href="#glossary">.htaccess</a> file with the
538 HTTP-AUTH directive or disallowing incoming HTTP requests at
539 one&#8217;s router or firewall will suffice (both of which
540 are beyond the scope of this manual but easily searchable with Google).</li>
541 </ul>
542 <h4 id="swekey">Swekey authentication</h4>
544 The Swekey is a low cost authentication USB key that can be used in
545 web applications.<br /><br />
546 When Swekey authentication is activated, phpMyAdmin requires the
547 users's Swekey to be plugged before entering the login page (currently
548 supported for cookie authentication mode only). Swekey Authentication is
549 disabled by default.<br /><br />
550 To enable it, add the following line to <tt>config.inc.php</tt>:
551 </p>
552 <pre>
553 $cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';
554 </pre>
556 You then have to create the <tt>swekey.conf</tt> file that will associate
557 each user with their Swekey Id. It is important to place this file outside
558 of your web server's document root (in the example, it is located in <tt>/etc</tt>). A self documented sample file is provided
559 in the <tt>contrib</tt> directory. Feel free to use it with your own
560 users' information.<br /><br />
561 If you want to purchase a Swekey please visit
562 <a href="http://phpmyadmin.net/auth_key">http://phpmyadmin.net/auth_key</a>
563 since this link provides funding for phpMyAdmin.

591 Note also that the <abbr title="Uniform Resource Locator">URL</abbr> on
592 some web servers are case&#8211;sensitive.
593 Don&#8217;t forget the trailing slash at the end.<br /><br />
595 Starting with version 2.3.0, it is advisable to try leaving this
596 blank. In most cases phpMyAdmin automatically detects the proper
597 setting. Users of port forwarding will need to set PmaAbsoluteUri (<a
598 href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1340187&amp;group_id=23067&amp;atid=377409">more info</a>).
599 A good test is to browse a table, edit a row and save it. There should
600 be an error message if phpMyAdmin is having trouble auto&#8211;detecting
601 the correct value. If you get an error that this must be set or if
602 the autodetect code fails to detect your path, please post a bug

639 no maximum length for this secret.<br /><br />
641 Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
642 makes a bit weaker security as this generated secret is stored in
643 session and furthermore it makes impossible to recall user name from
644 cookie.</dd>
646 <dt id="cfg_Servers">$cfg['Servers'] array</dt>
647 <dd>Since version 1.4.2, phpMyAdmin supports the administration of multiple

807 of these characters, escape them (I.E. use <tt>'my\_db'</tt> and not
808 <tt>'my_db'</tt>).<br />
809 This setting is an efficient way to lower the server load since the
810 latter does not need to send MySQL requests to build the available
811 database list. But <span class="important">it does not replace the

813 means only these databases will be displayed but

819 <br /><br />
821 As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the
822 databases in the left frame, so that you can individually arrange your databases.<br />
823 If you want to have certain databases at the top, but don't care about the others, you do not
824 need to specify all other databases. Use:
825 <tt>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</tt>

831 <dd>Regular expression for hiding some databases. This only hides them
832 from listing, but a user is still able to access them (using, for example,
833 the SQL query area). To limit access, use the MySQL privilege system.

835 For example, to hide all databases starting with the letter &#34;a&#34;, use<br />

976 Since release 2.3.0 you can store comments to describe each column for

980 Starting with release 2.5.0, comments are consequently used on the table
981 property pages and table browse view, showing up as tool-tips above the
982 column name (properties page) or embedded within the header of table in
983 browse view. They can also be shown in a table dump. Please see the
984 relevant configuration directives later on.<br /><br />
986 Also new in release 2.5.0 is a MIME-transformation system which is also
987 based on the following table structure. See <a href="#transformations">
988 Transformations</a> for further information. To use the
989 MIME-transformation system, your column_info table has to have the three
990 new fields 'mimetype', 'transformation', 'transformation_options'.
991 <br /><br />
993 To allow the usage of this functionality:
994 <ul><li>set up <a href="#pmadb">pmadb</a> and the linked-tables

996 <li>put the table name in

1024 Using

1045 Since release 3.3.x a tracking mechanism is available.
1046 It helps you to track every <abbr title="structured query language">SQL</abbr> command which
1047 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1048 and data definition statements. After enabling it you can create versions of tables.
1049 <br/><br/>
1050 The creation of a version has two effects:
1052 <ul>
1053 <li>phpMyAdmin saves a snapshot of the table, including structure and indexes.</li>
1054 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1055 </ul>
1057 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1058 For the report you can use filters, for example you can get a list of statements within a date range.
1059 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1060 In addition you can export the (filtered) report to a file or to a temporary database.

1382 <dt id="cfg_LeftFrameLight">$cfg['LeftFrameLight'] boolean</dt>
1383 <dd>Defines whether to use a select-based menu and display only the current
1384 tables in the left frame (smaller page). Only in Non-Lightmode you can
1385 use the feature to display nested folders using
1386 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1387 </dd>
1389 <dt id="cfg_LeftFrameDBTree">$cfg['LeftFrameDBTree'] boolean</dt>

1393 </dd>
1395 <dt id="cfg_LeftFrameDBSeparator">$cfg['LeftFrameDBSeparator']
1396 string or array</dt>
1397 <dd>The string used to separate the parts of the database name when showing
1398 them in a tree. Alternatively you can specify more strings in an array
1399 and all of them will be used as a separator.</dd>
1401 <dt id="cfg_LeftFrameTableSeparator">$cfg['LeftFrameTableSeparator'] string</dt>
1402 <dd>Defines a string to be used to nest table spaces. Defaults to '__'.
1403 This means if you have tables like 'first__second__third' this will be
1404 shown as a three-level hierarchy like: first &gt; second &gt; third.
1405 If set to FALSE or empty, the feature is disabled. NOTE: You should
1406 not use this separator at the beginning or end of a

1416 not.</dd>
1418 <dt id="cfg_ShowTooltipAliasDB">$cfg['ShowTooltipAliasDB'] boolean</dt>
1419 <dd>If tool-tips are enabled and a DB comment is set, this will flip the
1420 comment and the real name. That means that if you have a table called
1421 'user0001' and add the comment 'MyName' on it, you will see the name
1422 'MyName' used consequently in the left frame and the tool-tip shows
1423 the real name of the DB.</dd>

1426 <dd>Same as <a href="#cfg_ShowTooltipAliasDB" class="configrule">$cfg['ShowTooltipAliasDB']</a>, except this works for table names.
1428 When setting this to 'nested', the Alias of the Tablename is only used
1429 to split/nest the tables according to the
1430 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1431 directive. So only the folder is called like the Alias, the tablename itself
1432 stays the real tablename.</dd>

1463 &quot;tbl_change.php&quot; or &quot;sql.php&quot;.</dd>
1465 <dt id="cfg_ShowStats">$cfg['ShowStats'] boolean</dt>
1466 <dd>Defines whether or not to display space usage and statistics about databases
1467 and tables.<br />
1468 Note that statistics requires at least MySQL 3.23.3 and that, at this
1469 date, MySQL doesn't return such information for Berkeley DB tables.</dd>
1471 <dt><span id="cfg_ShowServerInfo">$cfg['ShowServerInfo'] </span>boolean</dt>

1484 does not check MySQL commands entered directly.<br /><br />
1486 Please note that to block the usage of phpinfo() in scripts, you
1487 have to put this in your <i>php.ini</i>:
1489 <pre>disable_functions = phpinfo()</pre>
1491 Also note that enabling the &quot;Change password &quot; link has no
1492 effect with &quot;config&quot; authentication mode: because of the

1494 be allowed to change their passwords.</dd>
1496 <dt id="cfg_SuggestDBName">$cfg['SuggestDBName'] boolean</dt>

1568 </dt>
1569 <dd>Defines whether to allow on the fly compression for GZip/BZip2
1570 compressed exports. This doesn't affect smaller dumps and allows users to
1571 create larger dumps that won't otherwise fit in memory due to php

1853 each row on a vertical lineup.<br /><br />
1855 The HeaderFlipType can be set to 'css' or 'fake'. When using 'css'
1856 the rotation of the header for horizontalflipped is done via CSS. If

1905 <br /><br />
1907 If you want different directory for each user, %u will be replaced
1908 with username.<br /><br />
1910 Please note that the file names must have the suffix &quot;.sql&quot;
1911 (or &quot;.sql.bz2&quot; or &quot;.sql.gz&quot; if support for

1914 This feature is useful when your file is too big to be uploaded via
1915 <abbr title="HyperText Transfer Protocol">HTTP</abbr>, or when file

1949 <tt>open_basedir</tt> for uploaded
1950 files, see <a href="#faq1_11"><abbr title="Frequently Asked Questions">FAQ</abbr>
1951 1.11</a>.
1952 <br /><br />
1954 If the directory where phpMyAdmin is installed is subject to an
1955 <tt>open_basedir</tt> restriction, you need to create a
1956 temporary directory in some directory accessible by the web
1957 server. However for security reasons, this directory should be outside
1958 the tree published by webserver. If you cannot avoid having this
1959 directory published by webserver, place at least an empty
1960 <tt>index.html</tt> file there, so that directory listing is not
1961 possible.
1962 <br /><br />
1964 This directory should have as strict permissions as possible as the only
1965 user required to access this directory is the one who runs the
1966 webserver. If you have root privileges, simply make this user owner of
1967 this directory and make it accessible only by it:
1968 <br /><br />
1970 <pre>
1971 chown www-data:www-data tmp
1972 chmod 700 tmp
1973 </pre>
1975 If you cannot change owner of the directory, you can achieve a similar
1976 setup using <abbr title="Access Control List">ACL</abbr>:
1978 <pre>
1979 chmod 700 tmp
1980 setfacl -m "g:www-data:rwx" tmp
1981 setfacl -d -m "g:www-data:rwx" tmp
1982 </pre>
1984 If neither of above works for you, you can still make the directory
1985 <code>chmod 777</code>, but it might impose risk of other users on
1986 system reading and writing data in this directory.

2016 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2017 or icon is always displayed on the left panel. If JavaScript is enabled in
2018 your browser, a click on this opens a distinct query window, which is
2019 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2020 changes to display a query box.<br /><br />
2022 The size of this query window can be customized with
2023 <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowHeight']</tt>
2024 - both integers for the size in pixels. Note that normally, those
2025 parameters will be modified in <tt>layout.inc.php</tt> for the
2026 theme you are using.<br /><br />
2028 If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
2029 from the results page (in the &quot;Showing Rows&quot; section)
2030 opens the query window and puts the current query
2031 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
2032 query in the right panel's query box.
2033 <br /><br />
2034 The usage of the JavaScript query window is recommended if you have a
2035 JavaScript enabled browser. Basic functions are used to exchange quite
2036 a few variables, so most 4th generation browsers should be capable to
2037 use that feature. It currently is only tested with Internet Explorer 6
2038 and Mozilla 1.x.
2039 <br /><br />
2040 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
2041 to a table, which has to be created by you (see <a
2042 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
2043 all your queries will be appended to the form, but only as long as
2044 your window is opened they remain saved.
2045 <br /><br />
2046 When using the JavaScript based query window, it will always get
2047 updated when you click on a new table/db to browse and will focus if
2048 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2049 the query window by checking the box "Do not overwrite this query from
2050 outside the window" below the query textarea. Then you can browse
2051 tables/databases in the background without losing the contents of the
2052 textarea, so this is especially useful when composing a query with
2053 tables you first have to look in. The checkbox will get automatically
2054 checked whenever you change the contents of the textarea. Please
2055 uncheck the button whenever you definitely want the query window to
2056 get updated even though you have made alterations.
2057 <br /><br />
2058 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
2059 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
2060 <br /><br />
2061 The query window also has a custom tabbed look to group the features.
2062 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
2063 default tab to be used when opening the query window. It can be set to
2064 either 'sql', 'files', 'history' or 'full'.</dd>

2089 where you edit x/y coordinates of those elements you can activate a
2090 scratchboard where all your elements are placed. By clicking on an
2091 element, you can move them around in the pre-defined area and the x/y
2092 coordinates will get updated dynamically. Likewise, when entering a
2093 new position directly into the input field, the new position in the
2094 scratchboard changes after your cursor leaves the input field.<br />
2095 You have to click on the 'OK'-button below the tables to save the new
2096 positions. If you want to place a new element, first add it to the
2097 table of elements and then you can drag the new element around.<br />
2098 By changing the paper size and the orientation you can change the size
2099 of the scratchboard as well. You can do so by just changing the
2100 dropdown field below, and the scratchboard will resize automatically,
2101 without interfering with the current placement of the elements.<br />
2102 If ever an element gets out of range you can either enlarge the paper
2103 size or click on the 'reset' button to place all elements below each
2104 other.<br />

2327 <h2 id="transformations">Transformations</h2>
2329 <ol><li><a href="#transformationsintro">Introduction</a></li>
2330 <li><a href="#transformationshowto">Usage</a></li>
2331 <li><a href="#transformationsfiles">File structure</a></li>
2332 </ol>
2334 <h3 id="transformationsintro">1. Introduction</h3>
2336 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2337 and the proper directives. Please see the <a href="#config">Configuration
2338 section</a> on how to do so.</p>
2340 <p> You can apply different transformations to the contents of each field. The
2341 transformation will take the content of each field and transform it with
2342 certain rules defined in the selected transformation.</p>
2344 <p> Say you have a field 'filename' which contains a filename. Normally you would
2345 see in phpMyAdmin only this filename. Using transformations you can transform
2346 that filename into a HTML link, so you can click inside of the phpMyAdmin
2347 structure on the field's link and will see the file displayed in a new browser
2348 window. Using transformation options you can also specify strings to
2349 append/prepend to a string or the format you want the output stored in.</p>
2351 <p> For a general overview of all available transformations and their options,
2352 you can consult your
2353 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2354 installation.</p>
2356 <p> For a tutorial on how to effectively use transformations, see our
2357 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2358 the official phpMyAdmin homepage.</p>
2360 <h3 id="transformationshowto">2. Usage</h3>
2362 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2363 clicking on the 'Structure' link for a table). There click on
2364 &quot;Change&quot; (or change icon) and there you will see three new fields at
2365 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2366 'Transformation options'.</p>
2368 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2369 that corresponds to the column's contents. Please note that
2370 transformations are inactive as long as no MIME-type is selected.</li>
2372 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2373 hopefully growing amount of pre-defined transformations. See below for information on
2374 how to build your own transformation.<br />
2376 There are global transformations and mimetype-bound transformations. Global transformations
2377 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2378 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2379 transformations which operate on the main mimetype (like 'image'), which will most likely
2380 take the subtype into regard, and those who only operate on a
2381 specific subtype (like 'image/jpeg').<br />
2383 You can use transformations on mimetypes for which the function was not defined for. There
2384 is no security check for you selected the right transformation, so take care of what the
2385 output will be like.</li>
2387 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2388 transform-function specific options here. Usually the transforms can operate with default
2389 options, but it is generally a good idea to look up the overview to see which options are
2390 necessary.<br />
2392 Much like the ENUM/SET-Fields, you have to split up several options using the format
2393 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2394 parsed as an array, leaving the first value the first element in the array, and so
2395 forth.<br />
2397 If you want to specify a MIME character set you can define it in the transformation_options.
2398 You have to put that outside of the pre-defined options of the specific mime-transform,
2399 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2400 for which you can specify 2 options and you want to append a character set, enter "'first
2401 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2402 the parameters: "'','','charset=us-ascii'".</li>
2403 </ul>
2405 <h3 id="transformationsfiles">3. File structure</h3>
2407 <p> All mimetypes and their transformations are defined through single files in
2408 the directory 'libraries/transformations/'.</p>
2410 <p> They are stored in files to ease up customization and easy adding of new
2411 transformations.</p>
2413 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2414 always work. It makes no sense to apply a transformation to a mimetype, the
2415 transform-function doesn't know to handle.</p>
2417 <p> One can, however, use empty mime-types and global transformations which should work
2418 for many mimetypes. You can also use transforms on a different mimetype they where built
2419 for, but pay attention to option usage as well as what the transformation does to your
2420 field.</p>
2422 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2423 any other transform function and provides some basic functions.</p>
2425 <p> There are 5 possible file names:</p>
2427 <ol><li>A mimetype+subtype transform:<br /><br />
2429 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2431 Please not that mimetype and subtype are separated via '_', which shall
2432 not be contained in their names. The transform function/filename may
2433 contain only characters which cause no problems in the file system as
2434 well as the PHP function naming convention.<br /><br />
2436 The transform function will the be called
2437 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2439 <b>Example:</b><br /><br />
2441 <tt>text_html__formatted.inc.php</tt><br />
2442 <tt>PMA_transform_text_html__formatted()</tt></li>
2444 <li>A mimetype (w/o subtype) transform:<br /><br />
2446 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2448 Please note that there are no single '_' characters.
2449 The transform function/filename may contain only characters which cause
2450 no problems in the file system as well as the PHP function naming
2451 convention.<br /><br />
2453 The transform function will the be called
2454 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2456 <b>Example:</b><br /><br />
2458 <tt>text__formatted.inc.php</tt><br />
2459 <tt>PMA_transform_text__formatted()</tt></li>
2461 <li>A mimetype+subtype without specific transform function<br /><br />
2463 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2465 Please note that there are no '__' characters in the filename. Do not
2466 use special characters in the filename causing problems with the file
2467 system.<br /><br />
2469 No transformation function is defined in the file itself.<br /><br />
2471 <b>Example:</b><br /><br />
2473 <tt>text_plain.inc.php</tt><br />
2474 (No function)</li>
2476 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2478 <tt>[mimetype].inc.php</tt><br /><br />
2480 Please note that there are no '_' characters in the filename. Do not use
2481 special characters in the filename causing problems with the file system.
2482 <br /><br />
2484 No transformation function is defined in the file itself.<br /><br />
2486 <b>Example:</b><br /><br />
2488 <tt>text.inc.php</tt><br />
2489 (No function)</li>
2491 <li>A global transform function with no specific mimetype<br /><br />
2493 <tt>global__[transform].inc.php</tt><br /><br />
2495 The transform function will the be called
2496 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2498 <b>Example:</b><br /><br />
2500 <tt>global__formatted</tt><br />
2501 <tt>PMA_transform_global__formatted()</tt></li>
2502 </ol>
2504 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2505 transform function.</p>
2507 <p> All filenames containing no '__' in themselves are not shown as valid transform
2508 functions in the dropdown.</p>
2510 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2511 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2512 without a transform function. Also note the introduction of a function description in
2513 the language files. For each function a $strTransformation_[filename without .inc.php]
2514 has to exist.</p>
2516 <p> You can use the template generator to generate new functions and entries in the
2517 language file.</p>
2519 <p> To create a new transform function please see
2520 <tt>libraries/transformations/template_generator.sh</tt>.
2521 To create a new, empty mimetype please see
2522 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2524 <p> A transform function always gets passed three variables:</p>
2526 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2527 you want to transform.</li>
2528 <li><b>$options</b> - Contains any user-passed options to a transform function
2529 as an array.</li>
2530 <li><b>$meta</b> - Contains an object with field information to your column.
2531 The data is drawn from the output of the
2532 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2533 function. This means, all object properties described on the
2534 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2535 available in this variable and can be used to transform a field accordingly
2536 to unsigned/zerofill/not_null/... properties.<br />
2537 The $meta-&gt;mimetype variable contains the original MIME-type of the
2538 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2539 </ol>

2736 </h4>
2738 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
2739 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2740 to take advantage of the new import features.</p>
2742 <p> The first things to check (or ask your host provider to check) are the
2743 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2744 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2745 All of these three settings limit the maximum size of data that can be
2746 submitted and handled by PHP. One user also said that post_max_size
2747 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2749 There exist several workarounds if your upload is too big or your
2750 hosting provider is unwilling to change the settings:</p>
2752 <ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
2753 feature. This allows one to
2754 upload a file to the server via scp, ftp, or your favorite file transfer
2755 method. PhpMyAdmin is then able to import the files from the temporary
2756 directory. More information is available in the <a href="#config">Configuration
2757 section</a> of this document.</li>
2758 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
2759 BigDump</a>) to split the files before uploading. We cannot support this
2760 or any third party applications, but are aware of users having success
2761 with it.</li>
2762 <li>If you have shell (command line) access, use MySQL to import the files
2763 directly. You can do this by issuing the &quot;source&quot; command from
2764 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2765 </ul>
2767 <h4 id="faq1_17">
2768 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2769 support?</a></h4>
2771 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2772 older MySQL versions, you need to use 2.8.x branch. phpMyAdmin can
2773 connect to your MySQL server using PHP's classic
2774 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2775 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2776 is available in php 5.0. The latter one should be used unless you have
2777 good reason not to do so.<br />
2778 When compiling php, we strongly recommend that you manually link the MySQL
2779 extension of your choice to a MySQL client library of at least the same
2780 minor version since the one that is bundled with some PHP distributions is
2781 rather old and might cause problems <a href="#faq1_17a">
2782 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.
2783 If your webserver is running on a windows system, you might want to try
2784 MySQL's
2785 <a href="http://dev.mysql.com/downloads/connector/php/">Connector/PHP</a>
2786 instead of the MySQL / MySQLi extensions that are bundled with the official
2787 php Win32 builds.</p>

2794 <p> You tried to access MySQL with an old MySQL client library. The version of
2795 your MySQL client library can be checked in your phpinfo() output.
2796 In general, it should have at least the same minor version as your server
2797 - as mentioned in <a href="#faq1_17">
2798 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2800 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2801 changed the authentication hash and your PHP is trying to use the old method.
2802 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2803 with the proper client library to match your MySQL installation. Your
2804 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.

2833 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called

3134 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3135 In your <i>php.ini</i> you will find a line</p>
3137 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3139 <p> change it to</p>
3141 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3143 <p> Then restart apache and it will work.</p>
3145 <p> Here is a fix suggested by Brad Ummer:</p>
3147 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3148 To do this, telnet to your server and go to the MySQL bin directory. In
3149 this directory there should be a file named <i>mysqladmin</i>. Type
3150 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3151 info about your MySQL server, including the socket
3152 (<i>/tmp/mysql.sock</i>, for example).</li>
3153 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3154 phpMyAdmin, you need to complete the socket information in the
3155 <i>config.inc.php</i>.<br />
3156 For example:
3157 <a href="#cfg_Servers_socket" class="configrule">
3158 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
3159 <br /><br />
3161 Please also make sure that the permissions of this file allow to be readable
3162 by your webserver (i.e. '0755').</li>
3163 </ul>
3165 <p> Have also a look at the
3166 <a href="http://www.mysql.com/doc/C/a/Can_not_connect_to_server.html">
3167 corresponding section of the MySQL documentation</a>.</p>

3194 <p> When you are using a port on your localhost, which you redirect via
3195 port-forwarding to another host, MySQL is not resolving the localhost
3196 as expected.<br />
3197 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
3198 MySQL (the commandline tool 'mysql' as well) always tries to use the socket

3208 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
3209 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
3210 <br />
3211 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
3212 should not delete the directory &quot;original&quot; or its underlying
3213 structure, because this is the system theme used by phpMyAdmin.
3214 &quot;original&quot; contains all images and styles, for backwards
3215 compatibility and for all themes that would not include images or css-files.
3216 <br /><br />
3218 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
3219 is enabled, you can select your favorite theme on the main page. Your
3220 selected theme will be stored in a cookie.<br /><br /></p>
3222 <p> To create a theme:</p>
3224 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
3225 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
3226 (by default <tt>themes</tt>)</li>
3227 <li>copy the files and directories from &quot;original&quot; to
3228 &quot;your_theme_name&quot;</li>
3229 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
3230 <li>put your new images in &quot;your_theme_name/img&quot;</li>
3231 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
3232 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
3233 contain your chosen theme name, that will be visible in user interface</li>
3234 <li>make a new screenshot of your theme and save it under
3235 &quot;your_theme_name/screen.png&quot;</li>
3236 </ul>
3238 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3239 theme verbose name, theme generation and theme version. These versions and
3240 generations are enumerated from 1 and do not have any direct dependence on
3241 phpMyAdmin version. Themes within same generation should be backwards
3242 compatible - theme with version 2 should work in phpMyAdmin requiring
3243 version 1. Themes with different generation are incompatible.</p>
3245 <p> If you do not want to use your own symbols and buttons, remove the
3246 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
3247 use the default icons and buttons (from the system-theme &quot;original&quot;).

4050 <a href="#faq6_13">6.13 I would like to create a database with a dot
4051 in its name.</a></h4>
4053 <p> This is a bad idea, because in MySQL the syntax &quot;database.table&quot;
4054 is the normal way to reference a database and table name. Worse, MySQL
4055 will usually let you create a database with a dot, but then you cannot
4056 work with it, nor delete it.</p>
4058 <h4 id="faqsqlvalidator">
4059 <a href="#faqsqlvalidator">6.14 How do I set up the
4060 <abbr title="structured query language">SQL</abbr> Validator?</a></h4>
4062 <p> To use it, you need a very recent version of PHP, 4.3.0 recommended, with
4063 <abbr title="Extensible Markup Language">XML</abbr>,
4064 <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
4065 <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
4066 On your system command line, run <tt>"pear install Net_Socket Net_URL
4067 HTTP_Request Mail_Mime Net_DIME SOAP"</tt> to get the necessary
4068 <abbr title="PHP Extension and Application Repository">PEAR</abbr> modules
4069 for usage.<br />
4070 On a more recent pear version, I had problems with the state of Net_DIME
4071 being beta, so this single command
4072 <tt>"pear -d preferred_state=beta install -a SOAP"</tt> installed all the
4073 needed modules.<br />
4074 If you use the Validator, you should be aware that any
4075 <abbr title="structured query language">SQL</abbr> statement you
4076 submit will be stored anonymously (database/table/column names,
4077 strings, numbers replaced with generic values). The Mimer
4078 <abbr title="structured query language">SQL</abbr>
4079 Validator itself, is &copy; 2001 Upright Database Technology.
4080 We utilize it as free SOAP service.</p>

4083 <a href="#faq6_15">6.15 I want to add a BLOB field and put an index on
4084 it, but MySQL says &quot;BLOB column '...' used in key specification without
4085 a key length&quot;.</a></h4>
4087 <p> The right way to do this, is to create the field without any indexes,
4088 then display the table structure and use the &quot;Create an index&quot;
4089 dialog. On this page, you will be able to choose your BLOB field, and
4090 set a size to the index, which is the condition to create an index on
4091 a BLOB field.</p>
4093 <h4 id="faq6_16">
4094 <a href="#faq6_16">6.16 How can I simply move in page with plenty
4095 editing fields?</a></h4>
4097 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4098 with many editing fields (table structure changes, row editing, etc.)
4099 (must be enabled in configuration - see.
4100 <a href="#CtrlArrowsMoving" class="configrule">$cfg['CtrlArrowsMoving']</a>).
4101 You can also have a look at the directive
4102 <a href="#DefaultPropDisplay" class="configrule">$cfg['DefaultPropDisplay']</a>
4103 ('vertical') and see if this eases up editing for you.</p>

4106 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
4107 WTF is this feature then useful for?</a></h4>
4109 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4110 on them. Otherwise you could just put a comment on the field. Because entering
4111 your own mimetype will cause serious syntax checking issues and validation,
4112 this introduces a high-risk false-user-input situation. Instead you have to
4113 initialize mimetypes using functions or empty mimetype definitions.<br />
4114 Plus, you have a whole overview of available mimetypes. Who knows all those
4115 mimetypes by heart so he/she can enter it at will?</p>
4117 <h4 id="faqbookmark">
4118 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
4119 can't I see any bookmarks below the query box? What is this variable for?
4120 </a></h4>
4122 <p> Any query you have executed can be stored as a bookmark on the page where the
4123 results are displayed. You will find a button labeled 'Bookmark this query'
4124 just at the end of the page.<br />
4125 As soon as you have stored a bookmark, it is related to the database you run
4126 the query on. You can now access a bookmark dropdown on each page, the query
4127 box appears on for that database.<br /><br />
4129 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4130 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
4131 which is put into the <i>value</i> input box on the query box page will
4132 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
4133 aware of that you HAVE to create a valid query, otherwise your query won't be
4134 even able to be stored in the database.<br />
4135 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
4136 for your query will remain the way it is, but will be stripped of the /**/
4137 chars. So you can use:<br /><br />
4139 <code>/*, [VARIABLE] AS myname */</code><br /><br />
4141 which will be expanded to<br /><br />
4143 <code>, VARIABLE as myname</code><br /><br />
4145 in your query, where VARIABLE is the string you entered in the input box. If
4146 an empty string is provided, no replacements are made.<br /><br />
4148 A more complex example. Say you have stored this query:<br /><br />
4149 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
4150 <br /><br />
4152 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
4153 the full query will be:<br /><br />
4155 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
4156 <br /><br />
4158 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query.<br />
4159 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
4160 spaces inserted there
4161 will be later also inserted as spaces in your query and may lead to unexpected
4162 results especially when
4163 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
4164 Your initial query which is going to be stored as a bookmark has to yield at
4165 least one result row so
4166 you can store the bookmark. You may have that to work around using well
4167 positioned &quot;/**/&quot; comments.</p>

4173 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4174 document should look like following one (assuming you have table
4175 exported in file <code>table.tex</code>):</p>

4186 <a href="#faq6_20">6.20 In MySQL 4, I see a lot of databases which are not mine, and cannot
4187 access them.
4188 </a></h4>
4190 <p> Upgrading to MySQL 4 usually gives users those global privileges: CREATE
4191 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4192 enable users to see all the database names.
4193 See this <a href="http://bugs.mysql.com/179">bug report</a>.<br /><br />

4200 possible values for a field, based on some foreign table?</a></h4>
4202 <p> You have to setup appropriate links between the tables, and also
4203 setup the &quot;display field&quot; in the foreign table. See
4204 <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
4205 6.6</a> for an example. Then, if there are 100 values or less in the
4206 foreign table, a drop-down list of values will be available.
4207 You will see two lists of values, the first list containing the key
4208 and the display field, the second list containing the display field
4209 and the key. The reason for this is to be able to type the first
4210 letter of either the key or the display field.<br /><br />
4212 For 100 values or more, a distinct window will appear, to browse foreign
4213 key values and choose one. To change the default limit of 100, see

4276 <p> First, for general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. We currently support streaming if you are running MySQL 5.1 with the PBXT and PBMS storage engines.</p>
4278 <ol>
4279 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of something like &quot;localhost&quot;.</li>
4280 <li>A current limitation is that your first login via phpMyAdmin to a freshly-started server must be done with an account that has the SUPER privilege.</li>
4281 <li>On your target database, go to Operations and in the &quot;BLOB Repository&quot; section, click &quot;Enable&quot;. This creates the PBMS system tables inside your database.</li>
4282 <li>Ensure that your target table is under the PBXT storage engine and has a LONGBLOB column.</li>
4283 <li>When you insert or update a row in this table, put a checkmark on the &quot;Upload to BLOB repository&quot; optional choice; otherwise, the upload will be done directly in your column instead of the repository.</li>
4284 <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example &quot;View image&quot;. A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time but in case it's incorrect, it's possible to edit it by clicking on the displayed MIME-type.</li>

4395 <h2 id="developers">Developers Information</h2>
4397 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
4398 great features have been written by other people and you too can help to
4399 make phpMyAdmin a useful tool.</p>
4401 <p> If you're planning to contribute source, please read the following
4402 information:</p>
4404 <ul><li>All files include <i>libraries/header.inc.php</i> (layout),.
4405 <i>libraries/common.lib.php</i> (common functions) and
4406 <i>config.inc.php</i>.<br />
4407 Only configuration data should go in <i>config.inc.php</i>. Please keep
4408 it free from other code.<br />
4409 Commonly used functions should be added to
4410 <i>libraries/common.lib.php</i> and more specific ones may be added
4411 within a library stored into the <i>libraries</i> sub-directory.</li>
4412 <li>Obviously, you're free to use whatever coding style you want. But
4413 please try to keep your code as simple as possible: beginners are
4414 using phpMyAdmin as an example application.<br />
4415 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4416 compliant on one hand, they fit the

4422 goes to <i>tbl_*.php</i>, db-related code to <i>db_*.php</i>,
4423 server-related tools to <i>server_*.php</i> and so on.</li>
4424 <li>Please don't put message strings in your code, instead add the string

4723 <h3>Original Credits of Version 2.1.0</h3>
4726 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4727 to create a web-based interface to MySQL using PHP3. Although I have not
4728 used any of his source-code, there are some concepts I've borrowed from
4729 him. phpMyAdmin was created because Peter told me he wasn't going to
4730 further develop his (great) tool.
4731 </p>
4733 Thanks go to
4734 </p>
4735 <ul>
4736 <li>Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4737 code for the check when dropping a table or database. He also suggested
4738 that you should be able to specify the primary key on tbl_create.php3. To
4739 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4740 well as a bug-report. Plus many smaller improvements.
4741 </li>
4742 <li>Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4743 were introduced in 1.3.0 (including quite significant ones like the
4744 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4745 bug-fixes and help.
4746 </li>
4747 <li>Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4748 language-independent by outsourcing the strings to a separate file. He
4749 also contributed the French translation.
4750 </li>
4751 <li>Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4752 tbl_select.php3, a feature to display only some fields from a table.
4753 </li>
4754 <li>Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4755 functions in tbl_change.php3. He also added the
4756 &quot;Query by Example&quot; feature in 2.0.
4757 </li>
4758 <li>Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4759 servers and is a regular contributor for bug-fixes.
4760 </li>
4761 <li>Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4762 features for 2.0.6.
4763 </li>
4764 </ul>
