   In my comments.php, I'm trying to list my pingbacks separate. If I remove the if statement (and endif) around the code below, the pages with pingbacks do indeed list the pingbacks. However, I don't want my h3 title to appear unless there are indeed pingbacks to display, so I built the following if statement around the pingback-generating code.

   I can't figure this out: the code does not get in my if statement. It just ignores that section. Any ideas why?

   echo "gets here 1";
   
   		if ( ! empty($comments_by_type['pings']) ) : //only placed in if there are indeed pingbacks
   
   			echo "does not get inside"; 
   
   			echo "<BR><h3 id='comments'>Pingbacks:</h3>";
   			echo "<div id='pings'>";
   
   			wp_list_comments('type=pings&callback=list_pings');
   
   			echo "</div>";
   
   		endif;
   
   			echo "gets here 2";

   How about this?
   

   <?php if ( ! empty($comments_by_type['pings']) ) :
   	$count = count($comments_by_type['pings']);
       ($count !== 1) ? $txt = "Pings/Trackbacks" : $txt = "Pings/Trackbacks"; ?>
   
       <h3 id="pings"><?php echo $count . " " . $txt; ?> for "<?php the_title(); ?>"</h3>
   
           <ul>
               <?php wp_list_comments('type=pings&max_depth=<em>'); ?>
           </ul>
   
   	<?php endif; ?>

   Nope, that isn't working either...

   Try:
   

   <?php if ( ! empty($comments_by_type['pings']) ) {
         echo "<br><h3 id='comments'>Pingbacks:</h3>";
         echo "<div id='pings'>";
   
   	wp_list_comments('type=pings&callback=list_pings');
   
   	 echo "</div>";
   
   } else {
         echo '';
   }
   ?>

   Emil,

   Thanks for your replies!

   Unfortunately, no, that doesn't work either. For that last echo ''; in the else I put in "inside" and it gets into the else.

   This means that for some reason the ! empty($comments_by_type['pings']) statement fails. I wonder if I don't have the variable $comments_by_type or the function "empty" or something? Any idea how to test for this to narrow it down?

   I am using WP 3.0.4 but I wonder if it is some kind of flaw in the theme I'm using ( Atahualpa 3.5.3 which is very complex and is touted as the most customizable theme available )...

   ok, convinced the comments_by_type is the problem... (I'm following this example.)

   I have in my functions.php the following which declares comments_by_type per the example linked, but I think it is flawed:

   <?php  
   
   //add-in by derek beck for
   //from www.wphacks.com/separating-trackbacks-from-comments-in-wordpress-2-7/
   
   function list_pings($comment, $args, $depth) {
   $GLOBALS['comment'] = $comment;
   ?>
   <li id="comment-<?php comment_ID(); ?>"><?php comment_author_link(); ?>
   <?php } ?>
   <?php
   add_filter('get_comments_number', 'comment_count', 0);
   function comment_count( $count ) {
   if ( ! is_admin() ) {
   global $id;
   $comments_by_type = &separate_comments(get_comments('status=approve&post_id=' . $id));
   return count($comments_by_type['comment']);
   } else {
   return $count;
   }
   }
   //end add-in
   ?>

   i got a hint from another forum that I need to set $comment_by_type as a global variable... how do I do this?

   ok, figured out that, but still calling it globally did not fix it... ugh...

   got it... the answer was here: http://wordpress.org/support/topic/comments_by_type-problems

   answer:

   Try adding the this
   <?php $comments_by_type = &separate_comments($comments); ?>
   directly before
   <?php if ( !empty($comments_by_type['comment']) ) : ?>

   This worked for me except I am using
   <?php if ( !empty($comments_by_type['pings']) ) : ?>
   instead of
   <?php if ( !empty($comments_by_type['comment']) ) : ?>
