Send Emails

Requires developing experience

Have you ever wanted to send users an email, but didn't want to use Rules?

And wouldn't it be nice to have a user interface to be able to edit the said email? A user interface you could show non-technical users, instead of you updating it all the time?

Introducting Send Emails, a light-weight module that provides a UI to create & update emails and a service to send the emails:

\Drupal::service('send_emails.mail')->notifyUsersByRole( $notificationRole, $emailTemplate);

You can also include custom TWIG variables using:

$autoLoginLinkUrl = ''; // If an empty string, will use the "Url for Auto Login Link" in the User Interface
$replyToEmail = ''; // If an empty string, will use the "Reply To Email" in the User Interface
$twigVariables = []; // Additional Twig variables that can be accessed in the email template
\Drupal::service('send_emails.mail')->notifyUser($user, $emailTemplate, $autoLoginLinkUrl, $replyToEmail, $twigVariables);

See ./src/EmailApi.php for more functions and documentation

Example

Here's how I use it in a custom module:

1. Install the module using the normal process (see documentation)
2. Create a new email
3. Go to Configuation > Send Emails Configuation: /admin/config/send_emails/emails#edit-emails-definitions
4. Define a new email using:
   
   director_private_notes | Send an email when a node "director_agendas" is created or updated and the "field_send_emails_notify" checkbox is checked
5. Click "Save"
6. The page should now have a new email that you can edit
7. Add the below code to a custom module
8. Flush the caches

function YOURMODULE_node_presave(Drupal\Core\Entity\EntityInterface $entity) {
  switch ($entity->bundle()) {
    case 'director_agendas':
      $notificationRole = 'testing';
      $emailTemplate = 'director_private_notes';
      
      if ($entity->hasField('field_send_emails_notify') && $entity->field_send_emails_notify->value == TRUE) {

          $result = \Drupal::service('send_emails.mail')->notifyUsersByRole( $notificationRole, $emailTemplate);

          $entity->set('field_send_emails_notify', FALSE);

          $lastNotificationTime =  \Drupal::service('date.formatter')->format($entity->changed->value, 'last_notified');
        
          $entity->set('field_send_emails_last_sent', 'Sent ' . $lastNotificationTime);

          \Drupal::messenger()->addMessage(
              t('%role have been notified', 
              ['%role' => ucfirst($notificationRole)])
          );

      }
      break;
  }
}
