Use of comment_reply_link_args filter

Question

i am trying to create a filter like this

add_filter('comment_reply_link_args','change_author_title');
function change_author_title( $args ) {
  $defaults = array(
        'add_below'     => 'comment',
        'respond_id'    => 'respond',
        'reply_text'    => __( 'Reply' ),
        /* translators: Comment reply button text. %s: Comment author name. */
        'reply_to_text' => __( 'THIS TEXT' ),
        'login_text'    => __( 'Log in to Reply' ),
        'max_depth'     => 0,
        'depth'         => 0,
        'before'        => '',
        'after'         => '',
    );

    $args = wp_parse_args( $args, $defaults );
    return $args;
}

What i actually need is to filter the 'reply_to_text' from the $defaults array.

The reason behind this is that i created a filter with get_comment_author

add_filter('get_comment_author', 'my_comment_author', 10, 2);
function my_comment_author( $author, $comment_ID ) {
    if (! is_admin()) {
    // Get the comment ID from WP_Query
    $comment = get_comment( $comment_ID );
    $authoremail = get_comment_author_email( $comment); 
    $user = get_user_by( 'email', $comment->comment_author_email );

    if (! email_exists($authoremail)) {
        if(mb_strlen($comment->comment_author, 'UTF-8')>13){
        $author = mb_substr($comment->comment_author,0,13, 'UTF-8').'.'; }
    } else {
        if( ! empty( $user->first_name ) ){
        $author = $user->first_name;  }
        else {
        return $author;  }
    } }

    return $author;
}

and i would like to pass the same output in $defaults array 'reply_to_text'.

Could someone give me a tip?

Thank you

Answer 1

You mean, something like this?

add_filter( 'comment_reply_link_args', 'change_author_title', 10, 2 );
function change_author_title( $args, $comment ) {
    $args['reply_to_text'] = 'Reply to ' . get_comment_author( $comment );
    return $args;
}

Explanation: I changed the function declaration so that it accepts the second parameter ($comment) which is the comment object (a WP_Comment instance), then I simply call the get_comment_author() which fires the get_comment_author hook. That way, your my_comment_author() function would be called and then you'd get the same author name for use with the reply_to_text arg.
