Sending mails using Cron in Drupal 8

#php #drupal #drupal8 #cron

In this post, we will be sending a simple birthday greeting email to the users using cron.

First, we have to create a module file in our custom module folder. We will name it as 'MODULE_NAME.module'. Using the hook_cron(), we will call a function to send the emails to the users where the mail-body is defined.

function MODULE_NAME_cron() { user_birthday_mails(); }
Enter fullscreen mode Exit fullscreen mode

Now we will fetch the details of the users, namely User-Name, Email-ID & Date of Birth.

In this scenario, I'm fetching the user details from a custom table.

<?php function user_birthday_mails() { // this is used to send HTML emails $send_mail = new \Drupal\Core\Mail\Plugin\Mail\PhpMail(); $current_m_d = date('m-d', \Drupal::time()->getRequestTime()); $fetch_query = \Drupal::database()->query("SELECT `firstname`, `email`, `dob` FROM `TABLE_NAME`"); $query_result = $fetch_query->fetchAll(); foreach($query_result as $result){ $birthday = explode('-', $result->dob); $birth_m_d = $birthday[1].'-'.$birthday[2]; $user_name = $result->firstname; $user_mail = $result->email; if($birth_m_d == $current_m_d){ $from = 'sitename@example.com'; $to = $user_mail; $message['headers'] = array( 'content-type' => 'text/html', 'MIME-Version' => '1.0', 'reply-to' => $from, 'from' => 'Site Admin <'.$from.'>' ); $message['to'] = $to; $message['subject'] = "Happy Birthday ".$user_name."!!!"; $message['body'] = 'Dear '.$user_name.', <br><br> We value your special day just as much as we value you. On your birthday, we send you our warmest and most heartfelt wishes.. <br><br> Regards,<br> Site Admin'; $send_mail->mail($message); \Drupal::logger('userinfo')->notice('Birthday mail sent to '.$user_name); }; } }
Enter fullscreen mode Exit fullscreen mode

I hope you find this simple use of cron helpful.
