   Hi. I'm using a custom taxonomy called 'relations' to do a poor man's related posts version (since I already use a related posts plugin for another purpose). I've set up a custom query to display posts sharing the 'relation' but when a posts has two relations it horribly fails (displays nothing).

   This is the code I use:

   function related_mess() {
   $relation = get_the_term_list( $post->ID, 'relations',' ', ', ', '' );
   if(!empty($relation)) { ?>
   <div stuff>
   <?php $rmquery =  new WP_query(array('relations' => $relation, 'showposts' =>10, 'post__not_in' => array($exclude)));
   while ( $rmquery->have_posts()) : $rmquery->the_post(); ?>
   [do stuff]

   I know where it goes wrong, it's simply 'relations' => wants a string and doesn't really get it. How do I fix this?

   Actually you would need to iterate through the $relations object and get the posts for each 'relations' term. Something like:

   <?php
   //for a given taxonomy, get the terms on this post, then get related posts. Also don't include the 'current post'
   $tax = 'relations';
   $tax_terms = wp_get_post_terms( $post->ID , $tax, '');
   $post_type = 'any';
   if ($tax_terms) {
     foreach ($tax_terms  as $tax_term) {
       $args=array(
         'post__not_in' => array($post->ID),
         'post_type' => $post_type,
         "$tax" => $tax_term->slug,
         'post_status' => 'publish',
         'posts_per_page' => -1,
         'caller_get_posts'=> 1
       );
   
       $my_query = null;
       $my_query = new WP_Query($args);
       if( $my_query->have_posts() ) {
         echo 'List of '.$post_type . ' where the taxonomy '. $tax . '  is '. $tax_term->name;
         while ($my_query->have_posts()) : $my_query->the_post(); ?>
           <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
           <?php
         endwhile;
       }
       wp_reset_query();
     }
   }
   ?>

   Ah, I see. That piece of coding didn't work either but I'll look if I can make a 'blend' of it.

   Replying to my old mess, this is how I actually 'fixed' it:

   function related_mess_revisited() {
   		global $wp_query;
   		$exclude = $wp_query->post->ID;
   		$all_relations = get_the_term_list( $post->ID, 'relations',' ', ', ', '' );
   		$relations = explode(",", $all_relations);
   		if (!empty($all_relations)) { ?>
   		Related to: <?php
   		foreach ($relations as $relation) {
   				$args = array(
   				'relations' => $relation,
   				'showposts' => 10,
   				'post__not_in' => array($exclude),
   				); ?>
   		<ul class="related-mess">
   		<?php $rmquery = new WP_query($args);
   		if( $rmquery->have_posts() ) {
   		while ( $rmquery->have_posts()) : $rmquery->the_post(); ?>
   [do stuff]
