12223	Adding a titles to comment levels with the walker class	danielpataki		"Hi Everyone! 

This is only my second post here, and my first feature request, so please excuse me if I have duplicated something or my solution is completely unsuitable. 

I am experimenting with the CMS capabilities of Wordpress, especially the enhanced post_type GUI in the new 3.0 alpha release. While building a sort of Yahoo Answers type platform, I wanted to have 1st level comments as answers to a question (a post), and 2nd level comments as comments on the answer (1st level comments). I wanted to label comments on an answer as ""comments"", but this is not really possible to do, to my knowledge, using ""wp_list_comments"".

I created my own function for wp_list_comments so I didn't have to modify Wordpress core, in order to get at the walker class at the bottom of wp_list_comments. I wanted to use start_lvl to add a title for comment level 2. However, start_lvl in ""class Walker_Comment extends Walker"" will only let you change the list type to ""ul"", ""ol"" or ""div"". My idea is to add an argument which would allow you to add a title, along with specifying it's heading (or surrounding tag). As I said, I am not an expert on Wordpress coding standards, so the following code may be completely off. 

{{{
/**
   * @see Walker::start_lvl()
   * @since unknown
   *
   * @param string $output Passed by reference. Used to append additional content.
   * @param int $depth Depth of comment.
   * @param array $args Uses 'style' argument for type of HTML list.
   * @param array $args Uses 'title' argument for title text.
   * @param array $args Uses 'title_heading' argument for title text heading level.
   */
	

function start_lvl(&$output, $depth, $args) {
  $GLOBALS['comment_depth'] = $depth + 1;
  
    switch ( $args['style'] ) {
      case 'div':
        break;
      case 'ol':
        echo ""<ol class='children'>\n"";
        break;
     default:
     case 'ul':
        echo ""<ul class='children'>\n"";
        break;
    }
	
	if (!empty ($args['title'])) {
	  
      if(!empty ($args['title_heading'])) {
	    echo '<'.$args['title_heading'].'>';
	  }
	  
	  echo $args['title'];

	  if(!empty ($args['title_heading'])) {
	    echo '</'.$args['title_heading'].'>';
	  }
	
	}
	
}
