Trigger: triggersomething. Run actions associated with an arbitrary event.

Here pressing a button is a trigger. We have defined a custom function as a trigger (trigger_example_triggersomething). It will ask for all actions attached to the 'triggersomething' event, prepare a basic 'context' for them and run all of them. This could have been implemented by a hook implementation, but in this demonstration, it will just be called in a form's submit.

This function is executed during the submission of the example form defined in this module.

Parameters

array $options: Array of arguments used to call the triggersomething function, if any.

Code

function trigger_example_triggersomething($options = array()) {

  // Ask the trigger module for all actions enqueued for the 'triggersomething'
  // trigger.
  $aids = trigger_get_assigned_actions('triggersomething');

  // Prepare a basic context, indicating group and "hook", and call all the
  // actions with this context as arguments.
  $context = array(
    'group' => 'trigger_example',
    'hook' => 'triggersomething',
  );
  actions_do(array_keys($aids), (object) $options, $context);
}
