1 system.api.php hook_action_info()

Declares information about actions.

Any module can define actions, and then call actions_execute() to make those actions happen in response to events.

An action consists of two parts:

  • an action definition (returned by this hook)
  • a function which performs the action (which by convention is named MODULE_description-of-function_action)

Return value

An associative array of action descriptions. The keys of the array: are the names of the action functions, and each corresponding value is an associative array with the following key-value pairs:

  • 'type': The type of object this action acts upon. Core actions have types 'node', 'user', 'comment', and 'system'.
  • 'label': The human-readable name of the action, which should be passed through the t() function for translation.
  • 'callback': Optional. A function name that will execute the action if the name of the action differs from the function name.
  • 'file': Optional. Relative path to a file from the module's directory that contains the callback function.
