Hooks, Actions, and Triggers In Drupal 7

Drupal proceeds through a series of events as it goes about its business. These internal events are times
when modules are allowed to interact with Drupal’s processing.

Drupal developers refer to these internal events as hooks because when one of the events occurs,
Drupal allows modules to hook into the path of execution at that point. Typical module development
involves deciding which Drupal event you want to react to, that is, which hooks you want to implement in your module.

• Event: Used in the generic programming sense, this term is generally understood
as a message sent from one component of a system to other components.
• Hook: This programming technique, used in Drupal, allows modules to “hook
into” the flow of execution. There are unique hooks for each operation that is
performed on the “hookable” object (e.g., hook_node_insert).
• Trigger: This refers to a specific combination of a hook and an operation with
which one or more actions can be associated. For example

An Event

  1. //bonjour.info
  2. name = Bonjour
  3. description = Displaying a welcome message in french.
  4. package = franch
  5. core = 7.x
  6. files[] = bonjour.module
  1. //bonjour.module
  2. /**
  3. * @file
  4. * Provide a bonjour welcome.
  5. */
  6. function bonjour_bonjour($title) {
  7. drupal_set_message('Maintenant, vous regardez: ' . check_plain($title));
  8. }
  9.  
  10. /**
  11. * Implementation of hook_node_view() action
  12. */
  13. function bonjour_node_view($node, $view_mode, $langcode) {
  14. if ($node->type == 'article' && $view_mode == 'full') {
  15. bonjour_bonjour($node->title);
  16. }
  17. }

An Simple Action

  1. /**
  2. *Implemenation of hook_action_info().
  3. */
  4. function bonjour_action_info() {
  5. return array(
  6. 'bonjour_bonjour_action' => array(
  7. 'type' => 'system',
  8. 'label' => t('Bonjour Messagei'),
  9. 'configurable' => FALSE,
  10. 'triggers' => array('node_view', 'node_insert'),
  11. ),
  12. );
  13. }
  14.  
  15. /**
  16. * A Drupal action.
  17. */
  18. function bonjour_bonjour_action() {
  19. bonjour_bonjour();
  20. }
  21.  
  22. /**
  23. * @file
  24. * Provide a bonjour welcome.
  25. */
  26. function bonjour_bonjour() {
  27. drupal_set_message('Bienvenue sur moi sparknotes');
  28. }

Drupal’s built-in trigger module allows you to associate some action with a certain event. In the
code, an event is defined as a unique hook-operation combination, such as “user hook, login operation”
or “node hook, insert operation.” When each of these operations occurs, trigger.module lets you trigger
an action. but first , you need to enable trigger module
