Attach an image to all emails notifications sent from a specific form.

Update: This option is now built-in. No need to use the code example.

add_filter('frm_notification_attachment', 'add_my_attachment', 10, 3);

function add_my_attachment($attachments, $form, $args){

//$args['entry'] includes the entry object

if ( $args['email_key'] == 1277 ) { //change 1277 to the ID of your email notification

  $attachments[] = ABSPATH . '/'.'wp-content/uploads/2015/02/filename.pdf'; //set the ABSOLUTE path to the image here

}

return $attachments;

}

When the box to include uploaded files in the email is checked in an upload field, you can remove them from some notifications.

add_filter('frm_notification_attachment', 'remove_my_attachment', 10, 3);

function remove_my_attachment($attachments, $form, $args) {

  if ( $args['email_key'] == 1277 ) { //change 1277 to the email ID that you would like to DROP the attachment for

    $attachments = array(); //remove all attachments

  }

  return $attachments;

}

// Replace with your specific notification IDs
$notification_ids_to_exclude = array( '123', '456', '789' );

if ( in_array( $args['email_key'], $notification_ids_to_exclude ) ) {
$attachments = array(); // Remove attachments for specific notifications
}

return $attachments;
