Most of us know how to send an e-mail with attachment. But do you know how you can do this using drupal 7? Not sure, then read on.

In this article, I am going to address 2 isssues.

  1. Sending an e-mail with an attachment.
  2. Sending an e-mail with multiple attachments.

Sending an e-mail in Drupal 7 with an attachment

The steps to be followed are:

  • Step 1: Install and enable the modules MIME mail and Mail system.
  • Step 2: Define hook_mail() in your custom module.

The synatx is as follows:

<?php
    function mymodule_mail($key, &$message, $params) {
      if (isset($params['subject'])) {
        $message['subject'] = $params['subject'];
      }
      if (isset($params['body'])) {
        $message['body'][] = $params['body'];
      }
      if (isset($params['attachment'])) {
        $message['params']['attachments'][] = $params['attachment'];
      }
    }
?>

This step defines the parameters to be sent as part of a mail.

  • Step 3: Now that we've defined the mail function , the next step is to call the function with proper parameters.

In order to call the hook_mail() , I am creating a send _mail (). Inside this function , we have to declare and define the variables which are to be passed to the mail function.

<?php 
    function mymodule_send_mail () {
      $to =$user->mail;//gets the current user's mail address
      $from = variable_get('site_mail', ''); //admin's mail address
      $body = 'This is a test mail';
      $attachment = array(
      'filecontent' => file_get_contents(DRUPAL_ROOT . '/' . filename),
      'filename' => 'filename.pdf';// You can change the name and extension of the file you need to send.
      'filemime' => 'text/plain',  
      );
      $message = drupal_mail('mymodule, 'message_key', $to, user_preferred_language($user), array('body' => $body, 'subject' => $subject, 'attachment' => $attachment), $from, TRUE); /* calls the mail functionality with parameters.
?> 

Sending an e-mail with multiple attachments

If you want to send multiple files as attachments,

  • step 1: Add the below code to the hook_mail function.
<?php
    $message['params']['attachments'][] = $params['attachment2'];
?>
  • step 2 : Modify the mymodule_send_mail() by adding the second attachment variable.
<?php
    $attachment2= array(
    'filecontent' => file_get_contents(DRUPAL_ROOT . '/' .'filename'),
    'filename' => 'file.jpeg', //Name of the file
    'filemime' => 'image/jpeg',//extension
    ); 
?> 
  • step3 : Add $attachment2 to the drupal_mail().
<?php
    $message = drupal_mail('churchpress', 'message_key', $to, user_preferred_language($user), array('body' => $body, 'subject' => $subject, 'attachment' => $attachment,'attachment2'=>$attachment2), $from, TRUE);
?>  

The above code worked for me. Hope this works for you too.!!!
