Trigger an action programmatically

Question

I have defined an action and want to trigger it from a hook.

We do not want to use the Rules module, because it is still buggy with Drupal 8. So, we cannot use rules_invoke_component().

What is the correct way to trigger an action? Do I need to construct a new Action object? Do I need a service? Is there documentation on that anywhere?

Answer 1

This works:

$action = \Drupal::entityTypeManager()
  ->getStorage('action')
  ->load('send_mail');
if ($action) {
  $action->execute($entity);
}

Answer 2

You have to pass $entity in as an array - try

$action = \Drupal::entityTypeManager()
  ->getStorage('action')
  ->load('send_mail');
if ($action) {
  $action->execute([$entity]);
}
