   I'm trying to add related posts to my single.php template. For various reasons, mostly flexibility, I don't want to use a related posts plugin.

   I want to be able to list a fixed number of posts, which use any of the tags used in the main post on a single post page, in reverse chronological order. I'm trying to write a second loop to do it.

   I've written this code but it's not working:

   <?php $posttags = get_the_tags();
   if ($posttags) {
   foreach($posttags as $tag) {
   $sep = ( $tags ) ? ',' : '';
   $tags .= $sep . '\'' . $tag->name . '\'';
      }
   };
   ?>
   
   <?php $my_query = new WP_Query("showposts=4&tag=$posttags");
   while ($my_query->have_posts()) : $my_query->the_post();
   $do_not_duplicate = $post->ID; ?>
   	<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a><br />
   <?php endwhile; ?>

   I cribbed the first chunk from here, http://wordpress.pastebin.ca/869461. It's code which should do what I want, but chooses posts at random - which I don't want. For some reason I can't get it to work at all - even without modification.

   Please help and no - I don't want to use a plugin. I've tried them and they don't work.

   Thanks in advance.

   Hi I’m searching for the same solution. Have you solved it?

   Another bump. I've been trying to do the same thing for the last two hours.

   Here there's a quite cool code but is still in a beta phase, and the author search for contributors.
