How to change i18n/l10n of #reply-title? (Old title: Comment reply link not working)

Question

I'm developing a new theme and plugins for it. Unfortunately, the comment reply link is broken. Instead of moving the comment reply textarea, the page is reloaded by adding e.g. ?replytocom=2#respond to the URL (corresponding to the value of the href attribute).

Here's a link to see what I mean: ... (No longer necessary to view link)

Thanks in advance for your help!

EDIT: I found out that it's caused by my "dirty" hack to modify the #reply-title. Which I do like this: functions.php.

// add variable to change comment form title
function add_comment_title_variable($content) {
    $output = $content;
    if(is_single() && comments_open()) $output .='<script type="text/javascript"> var commentFormTitle = "'.__('Leave a comment','theme-text-domain').'"; </script>';
    return $output;
}
add_filter('the_content','add_comment_title_variable');

Main JS file of my theme:

$(document).ready(function(){
    // [...]
    if(typeof(commentFormTitle) != 'undefined') $('#reply-title').html(commentFormTitle);
});

So, any hints how I can "individualize" the translation/textoutput of the comment form title without such dirty hack?

I kept it within the same question as other people who have the same problem with the comment reply link might be causing it the same way.

Thanks joschi81

Answer 1

It is because you need to enqueue comment-reply.js which is required for the jQuery effect.

Place the following in your header.php file within your head tag:

if ( is_singular() && get_option( 'thread_comments' ) )
    wp_enqueue_script( 'comment-reply' );

Solved! I found the optimal solution here: https://wordpress.org/support/topic/how-to-change-wording-of-leave-a-reply#post-1881213 I added my theme's textdomain like so:

// individual comment form title
function comment_reform ($arg) {
    $arg['title_reply'] = __('Leave a comment','theme-textdomain');
    return $arg;
}
add_filter('comment_form_defaults','comment_reform');

Sorry, the comment_form() function was still a bit unclear for me, especially when it comes to filter the default args.
