[Solved] How to change the Nicename that appears in the comments to the FirstName?

Hi @mariia-smolina,

Please put the following code in the functions.php file of the current active theme.

add_filter('wpdiscuz_comment_author', function ($authorName, $comment){
    if ($comment->user_id) {
        $first = get_user_meta($comment->user_id, 'first_name', true);
        $last = get_user_meta($comment->user_id, 'last_name', true);
        if ($first) {
            $authorName = $first;
            if ($last) {
                $authorName .= ' '. substr($last, 0, 1) . '.';
            }
        }
    }
    return $authorName;
}, 10, 2);

@mariia-smolina,

Please try the following one:

add_filter('wpdiscuz_comment_author', function ($authorName, $comment){
    if ($comment->user_id) {
        $first = get_user_meta($comment->user_id, 'first_name', true);
        $last = get_user_meta($comment->user_id, 'last_name', true);
        if ($first) {
            $authorName = $first;
            if ($last) {
                $authorName .= ' '. mb_substr($last, 0, 1) . '.';
            }
        }
    }
    return $authorName;
}, 10, 2);
