How one can type feedback within the "edit-comments.php" desk based mostly on a remark meta area?

Objective

Kind feedback within the "edit-comments.php" desk based mostly on a remark meta area after clicking on the title of a customized made column.

Context

For the sake of brevity let’s assume that when a remark is posted, a meta area referred to as "hearts" is assigned to it so that each one feedback have that area which is a optimistic int from 0 to 10. Of the daring steps talked about under, the primary three are given for context and work as meant, the issue is on the 4th step.

1. Creating the column

add_filter( 'manage_edit-comments_columns', 'hearts_add_comments_column' );
operate hearts_add_comments_column( $cols ) {
    $cols['hearts'] = 'Hearts';
    return $cols;
}

2. Populating the column

add_action( 'manage_comments_custom_column', 'hearts_column_content', 10, 2 );
operate hearts_column_content( $column, $comment_ID ) {
    swap ( $column ) :
        case 'hearts' : {           
            $hearts = get_comment_meta( $comment_ID, 'hearts', true );                  
            echo $hearts;           
            break;
        }
    endswitch;
}

3. Making the column sortable

add_filter( 'manage_edit-comments_sortable_columns', 'hearts_make_sortable' );
operate hearts_make_sortable( $cols ) {
    $cols['hearts'] = 'by_hearts';
    return $cols;
}

4. Kind based mostly on remark meta

That is the place the issues begin, one thing wants to vary within the following code which when examined independently, returns a sorted listing of feedback as meant:

add_action( 'pre_get_comments', 'hearts_orderby' );
operate hearts_orderby( $comments_query ) {
    $orderby = $comments_query->query_vars['orderby'];
 
    if( 'by_hearts' == $orderby ) {
        $comments_query->question(array( 
            'meta_key' => 'hearts',
            'orderby' => 'meta_value_num'
        ));         
    }
}

Important Error when clicking on the column’s title "Hearts" to type the column. Redirection to an empty web page with the next message:

Issues tried

The code under offers no errors, the feedback are listed however will not be sorted. If i take away the code under totally, the outcome is identical. The code is predicated on the final snippet of this web page.

add_action( 'pre_get_comments', 'hearts_orderby' );
operate hearts_orderby( $comments_query ) {
    $orderby = $comments_query->query_vars['orderby'];
 
    if( 'by_hearts' == $orderby ) {
        $comments_query->set('meta_key','hearts');
        $comments_query->set('orderby','meta_value_num');   
    }
}

Questions

1. Is it doable to one way or the other alter the hearts_orderby() operate within the 4th step to get the specified final result?
2. Is it doable to make use of a unique hook within the 4th step?
