    I’m trying to display related posts based on tags, but I’m running into a few things that just aren’t working right.

    Here’s the code I’m using:

    <?php global $post;
					$nextTagThumb='-1';
					$tags = wp_get_post_tags($post->ID);
					foreach ($tags as $tag) :
					?>

					<?php
					if ($tags) {
					$what_tag = $tags[($nextTagThumb+'1')]->term_id;
					$args=array(
					'tag__in' => array($what_tag),
					'post__not_in' => array($post->ID),
					'showposts'=>6,
					'caller_get_posts'=>1
					);
					$my_query = new WP_Query($args);
					if( $my_query->have_posts() ) {
					while ($my_query->have_posts()) : $my_query->the_post(); ?>

					<!--content goes here-->

					<?php endwhile;
					}
					wp_reset_query();
					$nextTagThumb = ($nextTagThumb+1);
					}
					?>

					<?php endforeach; ?>

    The two main problems I’m having are:

    – I can’t seem to limit what category it pulls from, which I’d like to be able to do. Otherwise, if I happen to have the same tag in a different category, it connects them, which is not ideal.

    – The ‘showposts’ line doesn’t seem to be working at all. I only want to show the first six related posts, but it shows all of them, no matter what number I enter.

    Any help would be much appreciated.

    You can see the site I’m using this on here: http://www.fiordilattegelato.com
    If you navigate to any single flavor page or single news item, you’ll see where the related posts come into play.

    Thanks!

    Try ‘posts_per_page’ instead of showposts.

    Yeah, that’s a little better. Still unpredictable though.

    If I have ‘posts_per_page’=>1, I’m still getting up to 4 or 5 related thumbs. And I just noticed that sometime I get the same related thumb twice.

    Any ideas?

    You could try not using the foreach loop and replace $what_tag and $args with this:

    $what_tag = wp_get_post_tags( $post->ID, array( 'fields' => 'ids' ) );
$args = array( 'tag__in' => $what_tag,
             'post__not_in' => array($post->ID),
             'posts_per_page' => 6,
             'ignore_sticky_posts' => 1 );

    That did the trick! Thanks very much! I just added an arg to exclude a category, and now it’s working perfectly.

    Here’s what worked if anyone else wants to use it:

    <?php global $post;
$nextTagThumb='-1';
$tags = wp_get_post_tags($post->ID);
?>

<?php
if ($tags) {
$what_tag = wp_get_post_tags( $post->ID, array( 'fields' => 'ids' ) );
$args = array( 'tag__in' => $what_tag,
             'post__not_in' => array($post->ID),
             'posts_per_page' => 6,
             'ignore_sticky_posts' => 1,
             'category__not_in' => 9
             );
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>

<!-- CONTENT HERE -->

<?php endwhile;
}
wp_reset_query();
$nextTagThumb = ($nextTagThumb+1);
}
?>
