Comment Author Name In Reply Form

2 comments

1. The WordPress function comment_form_title works only for users with Javascript disabled or pages without the comment-reply.js JavaScript loaded.

   WordPress may not fix this limitation at all
   Two tickets have been opened before and closed without fix.
   http://core.trac.wordpress.org/ticket/10084
   http://core.trac.wordpress.org/ticket/8639

   However I managed to get it work for the default twentyeleven theme by using some dirty fixes.
   Here is the code you may use as plugin.

   <?php
   /**
    * Plugin Name: Comment Form Title Fix
    * Plugin URI: 
    * Description: WordPress provides comment_form_title function to displays text based on comment reply status. This only affects users with Javascript disabled or pages without the comment-reply.js JavaScript loaded. This plugin provides dirty fix to remove this limitation.

   define('CFTF_REPLY_TEXT', 'Leave a Reply');
   define('CFTF_REPLY_TO_TEXT', 'Leave a Reply to %s');
   
   // Enable jquery
   add_action('init', 'my_script');
   function my_script() {
       wp_enqueue_script('jquery');
   }
   
   add_filter('comment_reply_link', 'cftf_reply_link');
   function cftf_reply_link($link) {
       global $comment;
   
       $author = get_comment_author();
       $replytext = sprintf( CFTF_REPLY_TO_TEXT, $author );
   
       $link = str_replace("onclick='return", "onclick='cftf_update_title("${replytext}"); return", $link);
       return $link;
   }
   
   add_action('wp_footer', 'cftf_javascript');
   function cftf_javascript() {
   ?>
   <script type="text/javascript">
   function cftf_update_title(title) {
       var temp = jQuery("#reply-title :first").html();
       jQuery("#reply-title").html(title + '<small>' +  temp + '</small>');
   }
   
   jQuery("#cancel-comment-reply-link").live('click', function() {
       var title = "<?php echo CFTF_REPLY_TEXT;?>";
       var temp = jQuery("#reply-title :first").html();
       jQuery("#reply-title").html(title + '<small>' +  temp + '</small>');
   });
   </script>
   <?php
   }
   

   Remember it may not work with all themes.

   Update:
   To make it work with the custom theme @Arg Geo uses.
   Replace the function cftf_javascript() as below

   function cftf_javascript() {
   ?>
   <script type="text/javascript">
   function cftf_update_title(title) {
       jQuery("#reply-title").html(title);
   }
   
   jQuery("#cancel-comment-reply-link").live('click', function() {
       var title = "<?php echo CFTF_REPLY_TEXT;?>";
       jQuery("#reply-title").html(title);
   });
   </script>
   <?php
   }

2. As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers.

   In the code tamilsweet provided replace:

   jQuery("#cancel-comment-reply-link").live('click', function() {
   

   with:

   jQuery("#respond").on('click', '#cancel-comment-reply-link', function() {
