 * Hi,
 * Could you give some more details about the changes that you made so far? Basically,
   as long as the args array uses the keys from here [https://codex.wordpress.org/Class_Reference/WP_Comment_Query#Default_Usage](https://codex.wordpress.org/Class_Reference/WP_Comment_Query#Default_Usage)
   everything should be fine when. Also, I think you can use `pre_get_comments` 
   hook to alter the comments results. Have you tried to use this?

 * Hi
    Thanks for your reply.I have used pre_get_comments hook.But nothing changed.
   I have used this code in my plugin.Please tell me what is the wrong with this
   code. function action_pre_get_comments( $array ) { // make action magic happen
   here… }
 * // add the action
    add_action( ‘pre_get_comments’, ‘action_pre_get_comments’,
   10, 1 ); Thanks in advance.

 * Hi,
 * Can you try this code, please?
 *     ```
       add_action('pre_get_comments', function($query) {
       	$query->meta_query = new WP_Comment_Query();
   
       	$query->query_vars['orderby'] = 'my_meta_key';
   
       	$query->meta_query->parse_query_vars( $query->query_vars );
       });
       ```
   
 * I just tried to use something like this:
 *     ```
       add_action('pre_get_comments', function($query) {
       	$query->meta_query = new WP_Comment_Query();
   
       	$query->query_vars['orderby'] = 'user_id';
       	$query->query_vars['order'] = 'ASC';
   
       	$query->meta_query->parse_query_vars( $query->query_vars );
       });
       ```
   
 * and it works very well.
