This module provides comment follow-up e-mail notification for anonymous and registered users.

Code

function comment_notify_comment($comment, $op) {
  global $user;

  // In theory, the update or insert operations are duplicates with publish which
  // would lead to duplicate messages.  _comment_notify_mailalert() protects against that.
  switch ($op) {
    case 'validate':

      // We assume that if they are non-anonymous then they have a valid mail.
      // For anonymous users, though, we verify that they entered a mail and let comment.module validate it is real.
      if (!$user->uid && $comment['notify'] && empty($comment['mail'])) {
        form_set_error('mail', t('If you want to subscribe to comments you must supply a valid e-mail address.'));
      }
      break;
    case 'publish':

      // And send notifications - the real purpose of the module.
      _comment_notify_mailalert($comment);
      break;
    case 'update':

      // In case they have changed their status, save it in the database.
      $sql = 'UPDATE {comment_notify} SET notify = %d WHERE cid = %d';

      }

      // And send notifications - the real purpose of the module.
