How to Replace Admin and User Comment Class

Snippets by IsItWP

Are you looking for a way to replace admin and user class names within your comments? While there’s probably a plugin for this, we have created a quick code snippet that you can use to replace admin and user comment class in WordPress.

WordPress creates a class name for your comments using your username and for security reasons you may wish to change them.


All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

// change the class that wordpress assigns to the comment
function change_comment_author_class( $classes ) {
    foreach( $classes as $key => $class ) {
        // change adminuser to your admin username
        if(strstr($class, "comment-author-adminuser")) {
            // change regularuser to the user you comment with
            $classes[$key] = 'comment-author-regularuser';
    return $classes;
// substitute a user name for the admin name
function change_comment_author($author)
    // change this to the admin username
    if(strstr($author,"adminuser")) { 
        // change this to the name of the user you comment with
        return "regularuser"; 
    return $author;
// apply the filters
add_filter( 'comment_class' , 'change_comment_author_class' );
add_filter( 'get_comment_author' , 'change_comment_author' );
