93 <!-- INTRODUCTION -->
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.

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>
165 <!-- INSTALLATION -->
173 </ol>
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
179 be used for this.
180 </p>
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
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
200 </li>
201 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
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
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
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
221 file) in the main (top-level) phpMyAdmin directory (the one
225 default value is okay for a particular setting, there is no
227 few directives to get going, a simple configuration may look
228 like this:
229 <pre>
230 <?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 ?>
237 </pre>
238 Or, if you prefer to not be prompted every time you log in:
239 <pre>
240 <?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 ?>
248 </pre>
249 For a full explanation of possible configuration values, see the
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
276 the webserver does not have the proper permissions you may see the
278 config/</tt> directory exists and has the proper permissions -
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
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
306 in your browser. phpMyAdmin should now display a welcome screen
307 and your databases, or a login dialog if using
309 authentication mode.</li>
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

328 <p> For a whole set of new features (bookmarks, comments,
330 tracking mechanism,
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>
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>

360 unpacked one. Configuration files from old versions may
361 require some tweaking as some options have been changed or removed; in

369 is version-specific.</p>
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
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
384 in this area!<br />
387 that your user/password pair are not in clear in the configuration file.
388 </li>
391 authentication modes are more secure: the MySQL login information does
392 not need to be set in the phpMyAdmin configuration file (except possibly
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

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 />

987 Also new in release 2.5.0 is a MIME-transformation system which is also

1026 Using
1028 you can specify an amount of history items you want to have on hold. On

1048 Since release 3.3.x a tracking mechanism is available.
1050 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1051 and data definition statements. After enabling it you can create versions of tables.
1052 <br/><br/>
1053 The creation of a version has two effects:
1055 <ul>
1057 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1058 </ul>
1060 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1061 For the report you can use filters, for example you can get a list of statements within a date range.
1062 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1063 In addition you can export the (filtered) report to a file or to a temporary database.

1866 each row on a vertical lineup.<br /><br />
1868 The HeaderFlipType can be set to 'css' or 'fake'. When using 'css'
1869 the rotation of the header for horizontalflipped is done via CSS. If

2030 or icon is always displayed on the left panel. If JavaScript is enabled in
2031 your browser, a click on this opens a distinct query window, which is
2032 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2033 changes to display a query box.<br /><br />
2035 The size of this query window can be customized with

2047 The usage of the JavaScript query window is recommended if you have a
2048 JavaScript enabled browser. Basic functions are used to exchange quite
2049 a few variables, so most 4th generation browsers should be capable to

2059 When using the JavaScript based query window, it will always get
2060 updated when you click on a new table/db to browse and will focus if
2061 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2062 the query window by checking the box "Do not overwrite this query from
2063 outside the window" below the query textarea. Then you can browse
2064 tables/databases in the background without losing the contents of the
2065 textarea, so this is especially useful when composing a query with
2066 tables you first have to look in. The checkbox will get automatically
2067 checked whenever you change the contents of the textarea. Please
2068 uncheck the button whenever you definitely want the query window to
2069 get updated even though you have made alterations.

2103 scratchboard where all your elements are placed. By clicking on an
2104 element, you can move them around in the pre-defined area and the x/y
2105 coordinates will get updated dynamically. Likewise, when entering a
2106 new position directly into the input field, the new position in the
2107 scratchboard changes after your cursor leaves the input field.<br />
2108 You have to click on the 'OK'-button below the tables to save the new
2109 positions. If you want to place a new element, first add it to the
2110 table of elements and then you can drag the new element around.<br />
2111 By changing the paper size and the orientation you can change the size
2112 of the scratchboard as well. You can do so by just changing the
2113 dropdown field below, and the scratchboard will resize automatically,
2114 without interfering with the current placement of the elements.<br />

2339 <!-- TRANSFORMATIONS -->
2345 </ol>
2349 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2351 section</a> on how to do so.</p>
2353 <p> You can apply different transformations to the contents of each field. The
2354 transformation will take the content of each field and transform it with
2355 certain rules defined in the selected transformation.</p>
2357 <p> Say you have a field 'filename' which contains a filename. Normally you would
2358 see in phpMyAdmin only this filename. Using transformations you can transform
2359 that filename into a HTML link, so you can click inside of the phpMyAdmin
2360 structure on the field's link and will see the file displayed in a new browser
2361 window. Using transformation options you can also specify strings to
2362 append/prepend to a string or the format you want the output stored in.</p>
2364 <p> For a general overview of all available transformations and their options,
2365 you can consult your
2366 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2367 installation.</p>
2369 <p> For a tutorial on how to effectively use transformations, see our
2371 the official phpMyAdmin homepage.</p>
2375 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2376 clicking on the 'Structure' link for a table). There click on
2377 "Change" (or change icon) and there you will see three new fields at
2378 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2379 'Transformation options'.</p>
2381 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2382 that corresponds to the column's contents. Please note that
2383 transformations are inactive as long as no MIME-type is selected.</li>
2385 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2386 hopefully growing amount of pre-defined transformations. See below for information on
2387 how to build your own transformation.<br />
2389 There are global transformations and mimetype-bound transformations. Global transformations
2390 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2391 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2392 transformations which operate on the main mimetype (like 'image'), which will most likely
2393 take the subtype into regard, and those who only operate on a
2394 specific subtype (like 'image/jpeg').<br />
2396 You can use transformations on mimetypes for which the function was not defined for. There
2397 is no security check for you selected the right transformation, so take care of what the
2398 output will be like.</li>
2400 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2401 transform-function specific options here. Usually the transforms can operate with default
2402 options, but it is generally a good idea to look up the overview to see which options are
2403 necessary.<br />
2405 Much like the ENUM/SET-Fields, you have to split up several options using the format
2406 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2407 parsed as an array, leaving the first value the first element in the array, and so
2408 forth.<br />
2410 If you want to specify a MIME character set you can define it in the transformation_options.
2411 You have to put that outside of the pre-defined options of the specific mime-transform,
2413 for which you can specify 2 options and you want to append a character set, enter "'first
2414 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2416 </ul>
2420 <p> All mimetypes and their transformations are defined through single files in
2421 the directory 'libraries/transformations/'.</p>
2423 <p> They are stored in files to ease up customization and easy adding of new
2424 transformations.</p>
2426 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2427 always work. It makes no sense to apply a transformation to a mimetype, the
2428 transform-function doesn't know to handle.</p>
2430 <p> One can, however, use empty mime-types and global transformations which should work
2431 for many mimetypes. You can also use transforms on a different mimetype they where built
2432 for, but pay attention to option usage as well as what the transformation does to your
2433 field.</p>
2435 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2436 any other transform function and provides some basic functions.</p>
2438 <p> There are 5 possible file names:</p>
2440 <ol><li>A mimetype+subtype transform:<br /><br />
2442 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2444 Please not that mimetype and subtype are separated via '_', which shall
2445 not be contained in their names. The transform function/filename may
2446 contain only characters which cause no problems in the file system as
2447 well as the PHP function naming convention.<br /><br />
2449 The transform function will the be called
2450 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2452 <b>Example:</b><br /><br />
2454 <tt>text_html__formatted.inc.php</tt><br />
2455 <tt>PMA_transform_text_html__formatted()</tt></li>
2457 <li>A mimetype (w/o subtype) transform:<br /><br />
2459 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2461 Please note that there are no single '_' characters.
2462 The transform function/filename may contain only characters which cause
2463 no problems in the file system as well as the PHP function naming
2464 convention.<br /><br />
2466 The transform function will the be called
2467 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2469 <b>Example:</b><br /><br />
2471 <tt>text__formatted.inc.php</tt><br />
2472 <tt>PMA_transform_text__formatted()</tt></li>
2474 <li>A mimetype+subtype without specific transform function<br /><br />
2476 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2478 Please note that there are no '__' characters in the filename. Do not
2479 use special characters in the filename causing problems with the file
2480 system.<br /><br />
2482 No transformation function is defined in the file itself.<br /><br />
2484 <b>Example:</b><br /><br />
2486 <tt>text_plain.inc.php</tt><br />
2487 (No function)</li>
2489 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2491 <tt>[mimetype].inc.php</tt><br /><br />
2493 Please note that there are no '_' characters in the filename. Do not use
2494 special characters in the filename causing problems with the file system.
2495 <br /><br />
2497 No transformation function is defined in the file itself.<br /><br />
2499 <b>Example:</b><br /><br />
2501 <tt>text.inc.php</tt><br />
2502 (No function)</li>
2504 <li>A global transform function with no specific mimetype<br /><br />
2506 <tt>global__[transform].inc.php</tt><br /><br />
2508 The transform function will the be called
2509 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2511 <b>Example:</b><br /><br />
2513 <tt>global__formatted</tt><br />
2514 <tt>PMA_transform_global__formatted()</tt></li>
2515 </ol>
2517 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2518 transform function.</p>
2520 <p> All filenames containing no '__' in themselves are not shown as valid transform
2521 functions in the dropdown.</p>
2523 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2524 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2525 without a transform function. Also note the introduction of a function description in
2526 the language files. For each function a $strTransformation_[filename without .inc.php]
2527 has to exist.</p>
2529 <p> You can use the template generator to generate new functions and entries in the
2530 language file.</p>
2532 <p> To create a new transform function please see
2533 <tt>libraries/transformations/template_generator.sh</tt>.
2534 To create a new, empty mimetype please see
2535 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2537 <p> A transform function always gets passed three variables:</p>
2539 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2540 you want to transform.</li>
2541 <li><b>$options</b> - Contains any user-passed options to a transform function
2542 as an array.</li>
2543 <li><b>$meta</b> - Contains an object with field information to your column.
2544 The data is drawn from the output of the
2546 function. This means, all object properties described on the
2548 available in this variable and can be used to transform a field accordingly
2549 to unsigned/zerofill/not_null/... properties.<br />
2550 The $meta->mimetype variable contains the original MIME-type of the
2551 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>

2663 We recommend the following setup for Apache servers running in safe mode,
2664 to enable uploads of files while being reasonably secure:</p>
2666 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2667 <li>give ownership to the Apache server's user.group:

2681 So the problem is that this package has a serious bug that was corrected
2682 ages ago in PHP (2001-01-28: see

2749 </h4>
2751 <p> Starting with version 2.7.0, the import engine has been re–written and these
2752 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2753 to take advantage of the new import features.</p>
2755 <p> The first things to check (or ask your host provider to check) are the
2756 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2757 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2758 All of these three settings limit the maximum size of data that can be
2759 submitted and handled by PHP. One user also said that post_max_size
2760 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2762 There exist several workarounds if your upload is too big or your
2763 hosting provider is unwilling to change the settings:</p>

2775 <li>If you have shell (command line) access, use MySQL to import the files
2776 directly. You can do this by issuing the "source" command from
2777 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2778 </ul>
2782 support?</a></h4>
2784 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2785 older MySQL versions, you need to use 2.8.x branch. phpMyAdmin can
2786 connect to your MySQL server using PHP's classic

2790 good reason not to do so.<br />
2791 When compiling php, we strongly recommend that you manually link the MySQL
2792 extension of your choice to a MySQL client library of at least the same
2793 minor version since the one that is bundled with some PHP distributions is
2796 If your webserver is running on a windows system, you might want to try

2846 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2847 "MySQL extension". This extension may be part of the PHP
2848 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2849 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2850 to load the extension but failed.<br /><br />

2932 message 'Errorcode: 13'. What does this mean?</a></h4>
2934 <p> This can happen due to a MySQL bug when having database / table names with

2936 To fix this, turn off this directive, convert all database and table names
2937 to lower case and turn it on again. Alternatively, there's a bug-fix

2942 and the fields are duplicated.</a></h4>
2944 <p> It is possible to configure Apache in such a way that PHP has problems
2945 interpreting .php files.</p>
2947 <p> The problems occur when two different (and conflicting) set of directives
2948 are used:</p>
2950 <pre>

2960 <tt>/etc/httpd/conf/httpd.conf</tt>, while
2961 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2962 The recommended way is with <tt>AddType</tt>, so just comment out
2963 the first set of lines and restart Apache:</p>
2965 <pre>
2966 #SetOutputFilter PHP
2967 #SetInputFilter PHP

2973 <p> This problem is known to happen when the server is running Turck MMCache
2974 but upgrading MMCache to version 2.3.21 solves the problem.</p>
2979 <p> Yes.<br />
2980 However, phpMyAdmin needs to be backwards compatible to php4. This is why
2981 phpMyAdmin disables the <tt>E_STRICT</tt> error_level in

3014 Table and script parts are optional. If you want

3057 <p> If your cluster consist of different architectures, PHP code used for

3059 pack/unpack functions in code. Only solution is to use mcrypt extension
3060 which works fine in this case.</p>
3065 <p> Yes but the default configuration values of Suhosin are known to cause
3066 problems with some operations, for example editing a table with many
3067 columns and no primary key or with textual primary key.
3068 </p>
3069 <p>
3070 Suhosin configuration might lead to malfunction in some cases and it can
3071 not be fully avoided as phpMyAdmin is kind of application which needs to
3072 transfer big amounts of fields in single HTTP request, what is something
3073 what Suhosin tries to prevent. Generally all
3074 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3075 <code>suhosin.get.*</code> directives can have negative effect on
3076 phpMyAdmin usability. You can always find in your error logs which limit
3077 did cause dropping of variable, so you can diagnose the problem and adjust
3078 matching configuration variable.
3079 </p>
3080 <p>
3081 The default values for most Suhosin configuration options will work in most

3110 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>
3112 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />

3119 </pre>
3121 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3122 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
3123 This is not specific to phpmyadmin, it's just the behavior of Apache.

3184 <p> Here is a fix suggested by Brad Ummer:</p>
3186 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3187 To do this, telnet to your server and go to the MySQL bin directory. In

3189 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3190 info about your MySQL server, including the socket
3191 (<i>/tmp/mysql.sock</i>, for example).</li>
3192 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3193 phpMyAdmin, you need to complete the socket information in the
3194 <i>config.inc.php</i>.<br />
3195 For example:
3197 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3198 <br /><br />
3200 Please also make sure that the permissions of this file allow to be readable
3201 by your webserver (i.e. '0755').</li>

3213 directive to <tt>FALSE</tt> in the phpMyAdmin configuration file. It helps
3214 sometime.<br />
3215 Also have a look at your PHP version number: if it contains "4.0b..."
3216 it means you're running a beta version of PHP. That's not a so good idea,
3217 please upgrade to a plain revision.</p>
3221 or a table, an error 404 (page not found) is displayed or, with <abbr title="HyperText Transfer Protocol">HTTP</abbr> or

3224 <p> Check the value you set for the
3226 directive in the phpMyAdmin configuration file.</p>
3230 password: YES)"-error when trying to access a MySQL-Server on a
3231 host which is port-forwarded for my localhost.</a></h4>
3233 <p> When you are using a port on your localhost, which you redirect via
3234 port-forwarding to another host, MySQL is not resolving the localhost
3235 as expected.<br />
3236 Erik Wasser explains: The solution is: if your host is "localhost"
3237 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
3238 connection for speeding up things. And that doesn't work in this configuration
3239 with port forwarding.<br />
3245 <p> Themes are configured with
3249 <br />
3251 should not delete the directory "original" or its underlying
3252 structure, because this is the system theme used by phpMyAdmin.
3253 "original" contains all images and styles, for backwards
3254 compatibility and for all themes that would not include images or css-files.
3255 <br /><br />
3258 is enabled, you can select your favorite theme on the main page. Your
3259 selected theme will be stored in a cookie.<br /><br /></p>
3261 <p> To create a theme:</p>
3263 <ul><li>make a new subdirectory (for example "your_theme_name") under
3265 (by default <tt>themes</tt>)</li>
3266 <li>copy the files and directories from "original" to
3267 "your_theme_name"</li>
3268 <li>edit the css-files in "your_theme_name/css"</li>
3269 <li>put your new images in "your_theme_name/img"</li>
3270 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
3271 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
3272 contain your chosen theme name, that will be visible in user interface</li>
3273 <li>make a new screenshot of your theme and save it under
3274 "your_theme_name/screen.png"</li>
3275 </ul>
3277 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3278 theme verbose name, theme generation and theme version. These versions and
3279 generations are enumerated from 1 and do not have any direct dependence on
3280 phpMyAdmin version. Themes within same generation should be backwards
3281 compatible - theme with version 2 should work in phpMyAdmin requiring
3282 version 1. Themes with different generation are incompatible.</p>
3284 <p> If you do not want to use your own symbols and buttons, remove the
3285 directory "img" in "your_theme_name". phpMyAdmin will
3286 use the default icons and buttons (from the system-theme "original").
3287 </p>
3291 what can I do?</a></h4>
3293 <p> Here are a few points to check:</p>
3295 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3297 directive empty. See also
3299 </li>
3300 <li>Maybe you have a broken PHP installation or you need to upgrade
3301 your Zend Optimizer. See
3303 http://bugs.php.net/bug.php?id=31134</a>.
3304 </li>
3305 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3306 set to the default (200) or another low value, you could get this
3307 error if your table has a high number of columns. Adjust this setting
3308 accordingly. (Thanks to Klaus Dorninger for the hint).
3309 </li>
3310 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3311 of ";" will cause this error. Replace it with "&;".
3312 </li>
3314 you might want to increase
3316 </li>
3317 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3318 </li>
3319 </ul>
3324 <p> To be able to see a progress bar during your uploads, your server must
3327 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3328 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3335 who logged out can not log in again in with the same nick.</a></h4>
3337 <p> This is related to the authentication mechanism (protocol) used by
3338 phpMyAdmin. To bypass this problem: just close all the opened
3339 browser windows and then go back to phpMyAdmin. You should be able to
3340 log in again.</p>
3344 limit error or a time limit error.</a></h4>
3346 <p> Compressed dumps are built in memory and because of this are limited to
3347 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3348 using
3350 (enabled by default). Zip exports can not be handled this way, so if you need
3351 Zip files for larger dump, you have to use another way.</p>
3355 when I rename a table or a column.</a></h4>
3357 <p> This is an InnoDB bug, see <a href="http://bugs.mysql.com/bug.php?id=21704">http://bugs.mysql.com/bug.php?id=21704</a>.</p>
3361 bundled with the MySQL server distribution.</a></h4>
3363 <p> The problem is that older versions of mysqldump created invalid comments like this:</p>
3365 <pre>
3366 -- MySQL dump 8.22
3367 --
3368 -- Host: localhost Database: database
3369 ---------------------------------------------------------
3370 -- Server version 3.23.54
3371 </pre>
3373 <p> The invalid part of the code is the horizontal line made of dashes that
3374 appears once in every dump created with mysqldump. If you want to run your
3375 dump you have to turn it into valid MySQL. This means, you have to add a
3376 whitespace after the first two dashes of the line or add a # before it:
3377 <br />
3378 <code>
3379 -- -------------------------------------------------------<br />
3380 </code>
3381 or<br />
3382 <code>
3383 #---------------------------------------------------------
3384 </code>
3385 </p>
3392 <p> Please note that you should not use the separating string multiple times
3393 without any characters between them, or at the beginning/end of your table
3394 name. If you have to, think about using another TableSeparator or disabling
3395 that feature</p>
3400 <p> In Relation view, being able to choose a table in another database,
3401 or having more than one index field in the foreign key.<br /><br/>

3403 LEFT JOIN from the foreign table.<br /><br/>
3404 </p>
3408 I get series of errors like "Warning: unable to parse url". How
3409 can this be fixed?</a></h4>
3410 <p>
3411 Your table neither have a primary key nor an unique one, so we must use a
3412 long expression to identify this row. This causes problems to parse_url
3413 function. The workaround is to create a primary or unique key.
3414 <br />
3415 </p>
3419 a MIME-Transformation onto!</a></h4>
3421 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3422 nested forms can be put inside the table where phpMyAdmin displays the results.
3423 You can, however, use any form inside of a table if keep the parent
3424 form-container with the target to tbl_row_delete.php and just put your own
3425 input-elements inside. If you use a custom submit input field, the form will
3426 submit itself to the displaying page again, where you can validate the
3427 $HTTP_POST_VARS in a transformation.
3429 For a tutorial on how to effectively use transformations, see our
3431 on the official phpMyAdmin-homepage.</p>
3435 MySQL server</a></h4>
3437 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3440 http://dev.mysql.com/doc/mysql/en/ANSI_mode.html</a>). Most important of all,
3441 the quote-character (") is interpreted as an identifier quote character and
3442 not as a string quote character, which makes many internal phpMyAdmin
3444 statements. There is no workaround to this behaviour. News to this item will
3445 be posted in Bug report
3446 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>

3451 more that one column with the same value
3452 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3453 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3455 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3456 can use it for the Edit and Delete links.</p>
3461 <p> phpMyAdmin uses a quick method to get the row count, and this method
3462 only returns an approximate count in the case of InnoDB tables. See
3464 a way to modify those results, but
3465 this could have a serious impact on performance.</p>
3470 <p> The number of records in queries containing COUNT and GROUP BY is
3471 not correctly calculated. Also, sorting results of a query like
3476 containing an hyphen.
3477 </a></h4>
3478 <p>
3479 The tests I have made with current MySQL 4.1.11 API shows that the
3480 API does not accept this syntax for the USE command. Enclosing the
3481 db name with backquotes works. For further confusion, no backquotes
3482 are needed with command-line mysql.

3486 <a href="#faq3_14">3.14 I am not able to browse a table when I don't have the right to SELECT one of the columns.</a></h4>
3487 <p>
3488 This has been a known limitation of phpMyAdmin since the beginning and
3489 it's not likely to be solved in the future.

3492 <!-- Begin: Excel import limitations -->
3495 <a href="#faq3_15">3.15 When I import an Excel spreadsheet, some cells with calculations do not display correctly.</a></h4>
3496 <p>
3497 phpMyAdmin uses the <a href="http://www.codeplex.com/PHPExcel/" target="_blank">PHPExcel</a> library to parse Excel XLS and XLSX spreadsheets.
3498 Therefore, any limitations that are listed on their page regarding Excel calculations will also apply here.
3499 <br /><br />
3500 PHPExcel will be kept up to date so as to make all improvements available to phpMyAdmin users.

3504 <a href="#faq3_16">3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import it, nothing happens.</a></h4>
3505 <p>
3506 Since Excel XLSX workbooks are already compressed, there is often times only a small benefit from compressing them yet again.
3507 Support for compressed Excel XLSX and XLS workbooks may be added in the future.
3508 </p>
3511 <a href="#faq3_17">3.17 When I import an Excel spreadsheet, my custom cell types are not represented as they are in Excel.</a></h4>
3512 <p>
3513 Excel's internal representation of custom cell types is rather muddled (especially in Excel 97-2003 binary XLS files). If possible,
3514 consider using a built-in type. These are almost always guarenteed to import correctly.

3521 <a href="#faq3_18">3.18 When I import a CSV file that contains multiple tables, they are lumped together into a single table.</a></h4>
3522 <p>
3523 There is no reliable way to differetiate tables in CSV format. For the time being, you will have to break apart CSV files containing multiple tables.

3530 <a href="#faq3_19">3.19 When I import a file and have phpMyAdmin determine the appropriate data structure it only uses int, decimal, and varchar types.</a></h4>
3531 <p>
3532 Currently, the import type-detection system can only assign these MySQL types to columns. In future, more will likely be added but for the time being
3533 you will have to edit the structure to your liking post-import.
3534 <br /><br />
3535 Also, you should note the fact that phpMyAdmin will use the size of the largest item in any given column as the column size for the appropriate type. If you
3536 know you will be adding larger items to that column then you should manually adjust the column sizes accordingly. This is done for the sake of efficiency.

3913 <p> Here is an example with the tables persons, towns and countries, all
3915 table, create it as explained in the configuration section. Then create the
3916 example tables:</p>
3918 <pre>
3919 CREATE TABLE REL_countries (
3920 country_code char(1) NOT NULL default '',
3921 description varchar(10) NOT NULL default '',
3922 PRIMARY KEY (country_code)
3923 ) TYPE=MyISAM;
3925 INSERT INTO REL_countries VALUES ('C', 'Canada');
3927 CREATE TABLE REL_persons (
3928 id tinyint(4) NOT NULL auto_increment,
3929 person_name varchar(32) NOT NULL default '',
3931 country_code char(1) NOT NULL default '',
3932 PRIMARY KEY (id)
3933 ) TYPE=MyISAM;
3935 INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
3936 INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');
3938 CREATE TABLE REL_towns (
3940 description varchar(30) NOT NULL default '',
3941 PRIMARY KEY (town_code)
3942 ) TYPE=MyISAM;
3944 INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
3945 INSERT INTO REL_towns VALUES ('M', 'Montréal');
3946 </pre>
3952 <li>in Links, for "country_code" choose "REL_countries->country_code"</li>
3956 </ul>
3964 <li>In the fields row, choose persons.person_name and click the
3966 <li>Do the same for towns.description and countries.descriptions in the
3969 the correct joins have been generated</li>
3971 </ul>
3975 <p>
3976 Starting from the previous example, create the pma_table_info as explained
3977 in the configuration section, then browse your persons table,
3978 and move the mouse over a town code or country code.
3979 <br /><br />
3980 See also <a href="#faq6_21"><abbr title="Frequently Asked Questions">FAQ</abbr> 6.21</a> for an additional feature that "display field"
3981 enables: drop-down list of possible values.
3982 </p>
3985 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3986 <p>
3989 <br /><br />
3990 Then you need to think about your schema layout. Which tables will go on
3991 which pages?
3992 </p>
3993 <ul>
3999 page and click Go. If you like, you
4001 linked tables onto the new page.</li>
4002 <li>Select the name of the new page (making sure the Edit radio button
4003 is selected) and click Go.</li>
4005 Coordinates are relative; your diagram will
4006 be automatically scaled to fit the page. When initially placing tables
4007 on the page, just pick any coordinates -- say, 50x50. After clicking
4009 position the element correctly.</li>
4011 first be sure to click the Save
4012 button beneath the list of tables and coordinates, to save any changes
4013 you made there. Then scroll all the way down, select the
4015 you want, and click Go.</li>
4016 <li>Internet Explorer for Windows may suggest an incorrect filename when
4021 browsers on Windows, do not have this problem.</li>
4022 </ul>
4026 columns!</a></h4>
4028 <p> No, it's MySQL that is doing
4034 underscores in the database name?</a></h4>
4036 <p> If you do not put a backslash before the underscore, this is a wildcard
4039 john2db ...<br /><br />
4041 If you put a backslash before the underscore, it means that the database
4042 name will have a real underscore.</p>
4046 statistics pages?</a></h4>
4057 if it already exists during the import. It does NOT drop the table after
4058 your export, it only affects the import file.</li>
4060 Otherwise, you may get an error if the table name exists but has a
4061 different structure.</li>
4063 (if any) will be included in backup.</li>
4065 field and table names formed with special characters are protected.</li>
4067 types set in the pmadb in the dump as
4069 </li>
4070 </ul>
4075 command, for better documentation (but resulting file is bigger).</li>
4077 once the INSERT verb and the table name.</li>
4080 </li>
4082 more info is provided in the
4084 but basically with this selected, invalid values are adjusted and
4085 inserted rather than causing the entire statement to fail.</li>
4086 </ul>
4090 in its name.</a></h4>
4093 is the normal way to reference a database and table name. Worse, MySQL
4094 will usually let you create a database with a dot, but then you cannot
4095 work with it, nor delete it.</p>
4108 for usage.<br />
4109 On a more recent pear version, I had problems with the state of Net_DIME
4110 being beta, so this single command
4112 needed modules.<br />
4113 If you use the Validator, you should be aware that any
4115 submit will be stored anonymously (database/table/column names,
4116 strings, numbers replaced with generic values). The Mimer
4119 We utilize it as free SOAP service.</p>
4123 it, but MySQL says "BLOB column '...' used in key specification without
4126 <p> The right way to do this, is to create the field without any indexes,
4128 dialog. On this page, you will be able to choose your BLOB field, and
4129 set a size to the index, which is the condition to create an index on
4130 a BLOB field.</p>
4134 editing fields?</a></h4>
4136 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4137 with many editing fields (table structure changes, row editing, etc.)
4138 (must be enabled in configuration - see.
4140 You can also have a look at the directive
4142 ('vertical') and see if this eases up editing for you.</p>
4146 WTF is this feature then useful for?</a></h4>
4148 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4149 on them. Otherwise you could just put a comment on the field. Because entering
4150 your own mimetype will cause serious syntax checking issues and validation,
4151 this introduces a high-risk false-user-input situation. Instead you have to
4152 initialize mimetypes using functions or empty mimetype definitions.<br />
4153 Plus, you have a whole overview of available mimetypes. Who knows all those
4154 mimetypes by heart so he/she can enter it at will?</p>
4158 can't I see any bookmarks below the query box? What is this variable for?
4159 </a></h4>
4161 <p> Any query you have executed can be stored as a bookmark on the page where the
4162 results are displayed. You will find a button labeled 'Bookmark this query'
4163 just at the end of the page.<br />
4164 As soon as you have stored a bookmark, it is related to the database you run
4165 the query on. You can now access a bookmark dropdown on each page, the query
4166 box appears on for that database.<br /><br />
4168 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4172 aware of that you HAVE to create a valid query, otherwise your query won't be
4173 even able to be stored in the database.<br />
4175 for your query will remain the way it is, but will be stripped of the /**/
4176 chars. So you can use:<br /><br />
4180 which will be expanded to<br /><br />
4184 in your query, where VARIABLE is the string you entered in the input box. If
4185 an empty string is provided, no replacements are made.<br /><br />
4187 A more complex example. Say you have stored this query:<br /><br />
4189 <br /><br />
4192 the full query will be:<br /><br />
4195 <br /><br />
4199 spaces inserted there
4200 will be later also inserted as spaces in your query and may lead to unexpected
4201 results especially when
4203 Your initial query which is going to be stored as a bookmark has to yield at
4204 least one result row so
4205 you can store the bookmark. You may have that to work around using well
4209 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4210 include exported table?</a></h4>
4212 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4213 document should look like following one (assuming you have table
4216 <pre>
4217 \documentclass{article} % or any class you want
4218 \usepackage{longtable} % for displaying table
4219 \begin{document} % start of document
4220 \include{table} % including exported table
4221 \end{document} % end of document
4222 </pre>
4226 access them.
4227 </a></h4>
4230 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4231 enable users to see all the database names.
4234 So if your users do not need those privileges, you can remove them and their
4235 databases list will shorten.</p>
4239 possible values for a field, based on some foreign table?</a></h4>
4241 <p> You have to setup appropriate links between the tables, and also
4245 foreign table, a drop-down list of values will be available.
4246 You will see two lists of values, the first list containing the key
4247 and the display field, the second list containing the display field
4248 and the key. The reason for this is to be able to type the first
4249 letter of either the key or the display field.<br /><br />
4251 For 100 values or more, a distinct window will appear, to browse foreign
4252 key values and choose one. To change the default limit of 100, see
4253 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4257 automatically when entering Browse mode for a table?</a></h4>
4259 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
4260 </p>
4264 Excel files, how can I enable that?</a></h4>
4266 <p> You can use
4268 which works out of the box, but phpMyAdmin supports direct export
4269 to Microsoft Excel version 97 and newer. For this to work, you need to set
4274 <pre>
4275 cd phpMyAdmin
4276 mkdir tmp
4277 chmod o+rwx tmp
4278 </pre>
4282 what happens to my column comments stored in pmadb?</a></h4>
4284 <p> Automatic migration of a table's pmadb-style column comments to the native
4285 ones is done whenever you enter Structure page for this table.</p>
4290 <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. Moreover, only PBMS 0.5.04 is supported.</p>
4292 <ol>
4293 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of something like "localhost".</li>
4294 <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>
4295 <li>On your target database, go to Operations and in the "BLOB Repository" section, click "Enable". This creates the PBMS system tables inside your database.</li>
4296 <li>Ensure that your target table is under the PBXT storage engine and has a LONGBLOB column.</li>
4297 <li>When you insert or update a row in this table, put a checkmark on the "Upload to BLOB repository" optional choice; otherwise, the upload will be done directly in your column instead of the repository.</li>
4298 <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example "View image". 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>
4299 </ol>
4304 <p> Click the first row of the range, hold the shift key and click the last row of the range. This works everywhere you see rows, for example in Browse mode or on the Structure page.</p>
4312 <p> Our Bug Tracker is located at
4314 under the Bugs section.<br /><br />
4316 But please first discuss your bug with other users:<br />
4322 existing language, where do I start?</a></h4>
4324 <p> Always use the current SVN version of your language file.
4326 don't know how to get the SVN version, please ask one of the developers.
4327 <br />
4328 Please note that we try not to use HTML entities like &eacute; in
4329 the translations, since we define the right character set in the file.
4330 With HTML entities, the text on JavaScript messages would not
4331 display correctly.
4332 However there are some entities that need to be there, for quotes
4333 ,non-breakable spaces, ampersands, less than, greater than.<br />
4334 You can then put your translations, as a zip file to avoid losing special
4335 characters, on the sourceforge.net translation tracker.<br />
4336 It would be a good idea to subscribe to the phpmyadmin-translators mailing
4337 list, because this is where we ask for translations of new messages.</p>
4341 phpMyAdmin. How should I proceed?</a></h4>
4346 <tt>git clone
4347 git://phpmyadmin.git.sourceforge.net/gitroot/phpmyadmin/phpmyadmin</tt><br />
4348 </li>
4350 <li>generate patch with your changes:

4356 </li>
4357 </ol>
4359 <p>More details on git are available on <a href="http://wiki.phpmyadmin.net/pma/Devel:Git">our wiki</a>.</p>
4361 <p> Write access to the repository is granted only to experienced developers who
4362 have already contributed something useful to phpMyAdmin.<br />
4368 <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>
4370 <p> Please refer to
4371 <a href="http://www.phpmyadmin.net/home_page/security.php">http://www.phpmyadmin.net/home_page/security.php</a>
4372 </p>
4377 <p> If you use Apache web server, phpMyAdmin exports information about
4378 authentication to Apache environment and it can be used in Apache logs.
4379 Currently there are two variables available:
4380 </p>
4381 <dl>
4383 <dd>User name of currently active user (he does not have to be logged
4384 in).</dd>
4391 </dl>
4392 <p>
4394 </p>
4395 <pre>
4398 </pre>
4399 <p>
4400 You can then use any log analyzing tools to detect possible break-in
4401 attempts.
4402 </p>
4408 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4409 It allows you to connect to local as well as remote servers.This requires you to enter
4410 server host name, username, password, port and the name of the database. Therefore you can
4411 now synchronize your databases placed on the same server or some remote server.
4412 </p>
4414 <p>For more details see <a href="./documentation-gsoc/Synchronization_User_Manual.htm">How to synchronize</a>

4751 <p>
4752 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4753 to create a web-based interface to MySQL using PHP3. Although I have not
4754 used any of his source-code, there are some concepts I've borrowed from
4755 him. phpMyAdmin was created because Peter told me he wasn't going to
4756 further develop his (great) tool.
4757 </p>
4758 <p>
4759 Thanks go to
4760 </p>
4761 <ul>
4763 code for the check when dropping a table or database. He also suggested
4764 that you should be able to specify the primary key on tbl_create.php3. To
4765 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4766 well as a bug-report. Plus many smaller improvements.
4767 </li>
4769 were introduced in 1.3.0 (including quite significant ones like the
4770 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4771 bug-fixes and help.
4772 </li>
4774 language-independent by outsourcing the strings to a separate file. He
4775 also contributed the French translation.
4776 </li>
4778 tbl_select.php3, a feature to display only some fields from a table.
4779 </li>
4781 functions in tbl_change.php3. He also added the
4783 </li>
4785 servers and is a regular contributor for bug-fixes.
4786 </li>
4788 features for 2.0.6.
4789 </li>
4790 </ul>
4791 <p>
