[Solved] Include post title in comment join text

Got it working with this:

add_filter("wpdiscuz_phrase", function ($phrase, $key, $args) {
    if ($key === "wc_comment_join_text") {
	$title = get_the_title(get_queried_object_id());
        $phrase = str_replace("Kommentar", "What are your thoughts about $title ?" , $phrase);
    }
    return $phrase;
}, 10, 3);

But now there results another question out of it: As the placeholder is the same like in reply to textarea it doesn't fit anymore. How can I hide the placeholder only in reply to form but keep it in the main comment form?

@jave,

You can use the CSS code: 

#wpdcom form.wpd_comm_form.wpd-secondary-form-wrapper .ql-editor::before{ 
    display: none;
}

Put the code in the Top Admin Bar > Customize > Additional CSS > "Additional CSS" textarea, save it, delete all caches and check again.

Thanks, working! Last question: Is it also possible to change the submit button text only for replies?

@jave,

You should use some JS code like this: 

jQuery(document).ready(function(){
      jQuery('#wpdcom #wpdiscuz_hidden_secondary_form input[type="submit"]').attr("value", "Your text");
});
