function mymodule_module_invoke($module, $hook) { // Perform some logic here hook_exec('mymodule', 'myhook', $vars); // Execute the hook }
function mymodule_entity_update($entity_type, $entity) { // Perform some logic here hook_exec('mymodule', 'entity_update', $entity_type, $entity); // Execute the hook }In this example, a custom module is invoked whenever an entity is updated. The 'mymodule_entity_update' function is defined to perform some logic and then execute the 'entity_update' hook using hook_exec. The hookExec module is part of the Drupal package library that provides a range of helper functions for extending the functionality of Drupal modules.
