Query Custom Taxonomies

    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(); ?>
