Code

function overlay_user_dismiss_message() {
  global $user;

  // It's unlikely, but possible that "access overlay" permission is granted to
  // the anonymous role. In this case, we do not display the message to disable
  // the overlay, so there is nothing to dismiss. Also, protect against
  // cross-site request forgeries by validating a token.
  if (empty($user->uid) || !isset($_GET['token']) || !drupal_valid_token($_GET['token'], 'overlay')) {
    return MENU_ACCESS_DENIED;

      'data' => array(
        'overlay_message_dismissed' => 1,
      ),
    ));
    drupal_set_message(t('The message has been dismissed. You can change your overlay settings at any time by visiting your profile page.'));

    // Destination is normally given. Go to the user profile as a fallback.
    drupal_goto('user/' . $user->uid . '/edit');
