How are related posts determined, and how to hide "no related posts found"?

[rolandixor]

I'd like to hide the related posts if there's nothing there. How would I go about doing this in my theme?

Also, how are related posts determined?

It display related article based on category. To remove the default use similar trick with this one #855 (comment)

I'm assuming we can pull from tags then? P.S. is it possible to assign a post to more than one category?

[danpros]

To pull from the tags you can use your custom functions. Create functions.php inside your theme and put your custom function there. With the current folder structure, it only supports 1 category per article.

Something like this could work?

<?php $related = get_related($post->related, true); ?>

<?php if (!empty($related)): // Check if $related is not empty ?>
    <?php foreach ($related as $r): ?>
        <h3><?php echo $r->title; ?></h3>
        <!-- Other content for each $r -->
    <?php endforeach; ?>
<?php else: ?>
    <p>No related items found.</p>
<?php endif; ?>

Yes this should work.
