Question

At my website there is “Login or register to post comments..”

I want to change the message to:
“Login or register to post comments(comments will be moderated)..”

Because plenty of spammers are just creating logins to post spam comments.
Although all comments are moderated now. Putting this message will give clear info that spamming may not be possible and spammers will not create logins.

Answer 1

Assuming you are using Drupal 6, the code that creates the comment form is in the file comments.module in the Drupal module directory. Fortunately, the function allows for theming.

What you can do is copy and paste the function theme_comment_post_forbidden($node) and place it in the template.php file in your theme directory. You will also need to rename the function, replacing ‘theme’ with your theme name.

For example, say your theme name is ‘utilitiesindia’. Then you will rename your function to utilitiesindia_comment_post_forbidden.

So, in your template.php file in a theme named utilitiesindia, use this function:

/**
 * Theme a "you can't post comments" notice.
 *
 * @param $node
 *   The comment node.
 * @ingroup themeable
 */
function utiltiesindia_comment_post_forbidden($node) {
  global $user;
  static $authenticated_post_comments;

  if (!$user->uid) {
    if (!isset($authenticated_post_comments)) {
      // We only output any link if we are certain, that users get permission
      // to post comments by logging in. We also locally cache this information.
      $authenticated_post_comments = array_key_exists(DRUPAL_AUTHENTICATED_RID, user_roles(TRUE, 'post comments') + user_roles(TRUE, 'post comments without approval'));
    }

    if ($authenticated_post_comments) {
      // We cannot use drupal_get_destination() because these links
      // sometimes appear on /node and taxonomy listing pages.
      if (variable_get('comment_form_location_'. $node->type, COMMENT_FORM_SEPARATE_PAGE) == COMMENT_FORM_SEPARATE_PAGE) {
        $destination = 'destination='. rawurlencode("comment/reply/$node->nid#comment-form");
      }
      else {
        $destination = 'destination='. rawurlencode("node/$node->nid#comment-form");
      }

      if (variable_get('user_register', 1)) {
        // Users can register themselves.
        return t('<a href="@login">Login</a> or <a href="@register">register</a> to post comments(comments will be moderated)', array('@login' => url('user/login', array('query' => $destination)), '@register' => url('user/register', array('query' => $destination)))
);
      }
      else {
        // Only admins can add new users, no public registration.
        return t('<a href="@login">Login</a> to post comments', array('@login' => url('user/login', array('query' => $destination))));
      }
    }
  }
}
