Wordpress - related posts by custom taxonomy problem
- by Nordin
Hello,
I'm trying to display related posts based on a custum taxonomy. I found a query at wordpress.org that kind of works. However the original post gets duplicated in the results multiple times. (words is the name of the custom taxonomy I use) What seems to happen is that the single post gets duplicated according to what amount showpost is set. Any idea's what could cause this?
The code:
<?php
//for in the loop, display all "content", regardless of post_type,
//that have the same custom taxonomy (e.g. words) terms as the current post
$backup = $post; // backup the current object
$found_none = '<h2>No related posts found!</h2>';
$taxonomy = 'words';// e.g. post_tag, category, custom taxonomy
$param_type = 'words'; // e.g. tag__in, category__in, but genre__in will NOT work
$post_types = get_post_types( array('public' => true), 'names' );
$tax_args=array('orderby' => 'none');
$tags = wp_get_post_terms( $post->ID , $taxonomy, $tax_args);
if ($tags) {
foreach ($tags as $tag) {
$args=array(
"$param_type" => $tag->slug,
'post__not_in' => array($post->ID),
'post_type' => $post_types,
'showposts'=>5,
'caller_get_posts'=>1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3>
<?php $found_none = '';
endwhile;
}
}
}
if ($found_none) {
echo $found_none;
}
$post = $backup; // copy it back
wp_reset_query(); // to use the original query again
?>
