Usage

To run the hook, copy the example below.

$classes = apply_filters( 'comment_class', $classes, $class, $comment_comment_id, $comment, $post_id ); 
                         
if ( !empty( $classes ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the comment_class callback 
function filter_comment_class( $classes, $class, $comment_comment_id, $comment, $post_id ) { 
    // make filter magic happen here... 
    return $classes; 
}; 
         
// add the filter 
add_filter( 'comment_class', 'filter_comment_class', 10, 5 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'comment_class', 'filter_comment_class', 10, 5 );
