Discover all action functions by invoking hook_action_info().

<?php

mymodule_action_info() {
  return array(
    'mymodule_functiondescription_action' => array(
      'type' => 'node',
      'description' => t('Save node'),
      'configurable' => FALSE,
      'hooks' => array(
        'nodeapi' => array('delete', 'insert', 'update', 'view'),
        'comment' => array('delete', 'insert', 'update', 'view'),
      )
    )
  );
}

?>

The description is used in presenting possible actions to the user for configuration. The type is used to present these actions in a logical grouping and to denote context. Some types are 'node', 'user', 'comment', and 'system'. If an action is configurable it will provide form, validation and submission functions. The hooks the action supports are declared in the 'hooks' array.

Übergabeparameter

$reset Reset the action info static cache.

Rückgabewert

An associative array keyed on function name. The value of each key is an array containing information about the action, such as type of action and description of the action, e.g.,

<?php

  $actions['node_publish_action'] = array(
    'type' => 'node',
    'description' => t('Publish post'),
    'configurable' => FALSE,
    'hooks' => array(
      'nodeapi' => array('presave', 'insert', 'update', 'view'),
      'comment' => array('delete', 'insert', 'update', 'view'),
    ),
  );
  
?>
