6 * Contains the view analyze tool code.
8 * This tool is a small plugin manager to perform analysis on a view and
9 * report results to the user. This tool is meant to let modules that
10 * provide data to Views also help users properly use that data by
11 * detecting invalid configurations. Views itself comes with only a
12 * small amount of analysis tools, but more could easily be added either
13 * by modules or as patches to Views itself.
17 * Analyze a review and return the results.
20 * An array of analyze results organized into arrays keyed by 'ok',
21 * 'warning' and 'error'.
23 function views_analyze_view(&$view) {
24 $view->init_display();
25 $messages = module_invoke_all('views_analyze', $view);
31 * Format the analyze result into a message string.
33 * This is based upon the format of drupal_set_message which uses separate
34 * boxes for "ok", "warning" and "error".
36 function views_analyze_format_result($view, $messages) {
37 if (empty($messages)) {
38 $messages = array(views_ui_analysis(t('View analysis can find nothing to report.'), 'ok'));
41 $types = array('ok' => array(), 'warning' => array(), 'error' => array());
42 foreach ($messages as $message) {
43 if (empty($types[$message['type']])) {
44 $types[$message['type']] = array();
46 $types[$message['type']][] = $message['message'];
50 foreach ($types as $type => $messages) {
52 if (count($messages) > 1) {
53 $message = theme('item_list', $messages);
56 $message = array_shift($messages);
60 $output .= "<div class=\"$type\">$message</div>";
68 * Format an analysis message.
70 * This tool should be called by any module responding to the analyze hook
71 * to properly format the message. It is usually used in the form:
73 * $ret[] = views_ui_analysis(t('This is the message'), 'ok');
76 * The 'ok' status should be used to provide information about things
77 * that are acceptable. In general analysis isn't interested in 'ok'
78 * messages, but instead the 'warning', which is a category for items
79 * that may be broken unless the user knows what he or she is doing,
80 * and 'error' for items that are definitely broken are much more useful.
83 * The message to report.
85 * The type of message. This should be "ok", "warning" or "error". Other
86 * values can be used but how they are treated by the output routine
89 function views_ui_analysis($message, $type = 'error') {
90 return array('message' => $message, 'type' => $type);
94 * Implementation of hook_views_analyze().
96 * This is the basic views analysis that checks for very minimal problems.
97 * There are other analysis tools in core specific sections, such as
98 * node.views.inc as well.
100 function views_ui_views_analyze($view) {
102 // Check for something other than the default display:
103 if (count($view->display) < 2) {
104 $ret[] = views_ui_analysis(t('This view has only a default display and therefore will not be placed anywhere on your site; perhaps you want to add a page or a block display.'), 'warning');
