richardukI've been beating my brains out on this and can't get anywhere.
The code below checks for tags in a post, then outputs any other posts that have any of those tags and are in the specified category.
What I want to do is order the posts with the ones with the most tags in common first, on the grounds that they're probably going to be the most relevant posts.
I can count the tags easily enough for each post:
$posttags = array();
$posttags = get_the_tags();
$count= count($posttags);I could then sort the array. However, I'm struggling beyond this e.g. associating each count with a post ID and then outputting the relevant post.
I'm guessing I'll need a second loop but I'm really floundering. I guess the second loop would contain something like this to start with, but it's a wild guess:
<?php $my_query2 = new WP_Query('');
while ($my_query2->have_posts()) : $my_query2->the_post();
$ordertags[] = $post->ID ?>Any help much appreciated.
Here's the basic code, based on MichaelH's code here http://wordpress.org/support/topic/247918?replies=14
and also here http://www.3mind.at/2009/05/06/code-highlighting/
<?
$backup = $post;
$tags = wp_get_post_tags($post->ID);
$tagIDs = array();
if ($tags) {
$tagcount = count($tags);
for ($i = 0; $i < $tagcount; $i++)
{
$tagIDs[$i] = $tags[$i]->term_id;
}
$args=array( 'tag__in' => $tagIDs,'post__not_in' => array($post->ID), 'showposts'=>5, 'caller_get_posts'=>1, 'cat' => 23);
$my_query = new WP_Query($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>
<? endwhile;
}
}
else { ?>
<h2>No related posts found!</h2>
<?php }
$post = $backup;
wp_reset_query();
?>
