Synchronize actions that are provided by modules.

Actions provided by modules are synchronized with actions that are stored in the actions table. This is necessary so that actions that do not require configuration can receive action IDs. This is not necessarily the best approach, but it is the most straightforward.

Übergabeparameter

$delete_orphans Boolean if TRUE, any actions that exist in the database but are no longer found in the code (for example, because the module that provides them has been disabled) will be deleted.

Code

includes/actions.inc, line 254

<?php
function actions_synchronize($delete_orphans = FALSE) {
  $actions_in_code = actions_list(TRUE);
  $actions_in_db = db_query("SELECT aid, callback, description FROM {actions} WHERE parameters = ''")->fetchAllAssoc('callback', PDO::FETCH_ASSOC);

  // Go through all the actions provided by modules.
  foreach ($actions_in_code as $callback => $array) {
    // Ignore configurable actions since their instances get put in when the
    // user adds the action.
    if (!$array['configurable']) {
      // If we already have an action ID for this action, no need to assign aid.
      if (array_key_exists($callback, $actions_in_db)) {
        unset($actions_in_db[$callback]);
      }
      else {
        // This is a new singleton that we don't have an aid for; assign one.
        db_insert('actions')
