User Registration Notification and hook_mail()

Draft status not available -- AWAITING PEER REVIEW
Prerequisites: 
  • Basic knowledge of PHP and CSS required
  • Knowledge of basic module creation
Steps: 

Step 1: Create a new module. Name it register_notify. See the lesson about creating new modules for details about specific steps.

Step 2: Review the API documentation for the hook_user_insert() function at http://api.drupal.org/api/drupal/modules!user!user.api.php/function/hook... . This hook gets called whenever a new user is created. You can take any custom action you want here. We’ll send an email notification Paste the following code into your new module:

/**
* Implements hook_user_insert().
*/
function register_notify_user_insert(&$edit, &$account) {

}

Step 3: Use hook_mail() to prepare a message to pass to drupal_mail(). hook_mail() is tragically complicated, but no fear. You can tame the beast! For details, see the documentation page at http://api.drupal.org/api/drupal/modules!system!system.api.php/function/... .

/**
* Implements hook_mail().
*/
function register_notify_mail($key, &$message, $params) {
switch ($key) {
case ‘new_user_notify’:
$message[‘subject’] = t(‘A new user was created!’, array());
$message[‘body’][] = t(‘’, array());
break;
}

}

Step 4:
Enable the register_notify module. Register a new user at /user/register and verify that the admin receives an email notification.
