Disable HTML in WordPress Comments

July 2, 2011 • Tips and Tricks • tags comments, html, Wordpress

In your SPAM folde there are many comments with alot of HTML codes which are basically links. That is how most spammers add links. But you can disable HTML in WordPress Comments to be functional. So if someone uses the strong code, it will not bold the text etc.

All you have to do is simply open your functions.php and add the following code:

    // This will occur when the comment is posted
    function plc_comment_post( $incoming_comment ) {
 
    // convert everything in a comment to display literally
    $incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);
 
    // the one exception is single quotes, which cannot be #039; because WordPress marks it as spam
    $incoming_comment['comment_content'] = str_replace( "'", ''', $incoming_comment['comment_content'] );
 
    return( $incoming_comment );
    }
 
    // This will occur before a comment is displayed
    function plc_comment_display( $comment_to_display ) {
 
    // Put the single quotes back in
    $comment_to_display = str_replace( ''', "'", $comment_to_display );
 
    return $comment_to_display;
