    Below is my function, 

    function my_related_posts() {
if (is_single()) {
	global $post;
	$current_post = $post->ID;
	$categories = get_the_category();
foreach ($categories as $category) :
	?>
<div class="recent-posts">
		<?php
			$posts = get_posts('numberposts=5&category='. $category->term_id . '&exclude=' . $current_post);
			foreach($posts as $post) :
		?>
	<div class="col-md-4">
	<div class="featured-image-featured" class="img-responsive">
		<?php if(has_post_thumbnail()) { the_post_thumbnail();} else { ?><img src="https://placehold.it/730x350" class="img-responsive"><?php }?>

	</div>
	<h4><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4>
	<div id="date-related">
					  <span id="day"><?php echo get_the_date('d'); ?></span>
					  <span id="month"><?php echo get_the_date('M'); ?></span>
					  <span id="year"><?php echo get_the_date('Y'); ?></span>
				</div>
	<article>
	<?php the_excerpt(); ?>
	</article>
	<div class="categories-title">Tags</div>
					  <div class="categories">
					  <?php
						$categories = get_the_category();
						$separator = ' ';
						$output = '';
						if($categories){
						foreach($categories as $category) {
						$output .= '<span>'.$category->cat_name.'</span>'.$separator;
						}
						echo trim($output, $separator);
						}
						?>
					</div>
</div>

	<?php endforeach; ?><?php endforeach; ?>
</div>
	<?php
		}
	wp_reset_query();
}
add_action('thesis_hook_after_post','my_related_posts');

    I need to make it show ‘No related posts’ if there aren’t any.

    I also need this to only show 3 related posts. Much appreciated.

    Ryan.

    show ‘No related posts’ if there aren’t any

    general structure:

    if( $posts ) :
	foreach($posts as $post) :
//...etc...//
endforeach;
else:
    echo 'No related posts.';
endif;

    only show 3 related posts

    I’ve tried to add that else: echo 'No related posts.'; endif; after each of the endforeach; but neither of them work?

    you might need to read-up on the if/else php structure – https://www.w3schools.com/php/php_if_else.asp

    as you are trying to implement the code into a commercial theme, you might need to contact the theme’s developer (diythemes) directly for support;

    This is a theme I am building myself, but I copied this code from somewhere but can’t remember where.. didn’t bookmark it for some reason. I’ll take a look at the first link. Cheers.

    You open three foreach loops and only close two of them. That’s a pretty big deal no matter what, but especially when you use the function in certain contexts.

    If this entire function is meant to display related posts, then change the following:
    $posts = get_posts('numberposts=5&category='. $category->term_id . '&exclude=' . $current_post);
    to
    $posts = get_posts(‘numberposts=3&category=’. $category->term_id . ‘&exclude=’ . $current_post);

    As for displaying a message if no related posts are present, alchymyth’s answer is correct. You have to wrap the entire second foreach loop in an if statement that checks to see if your variable $posts has anything contained inside it. If it does, echo out the loop. If not, display the “no related posts” message.

    Sorry guys.

    I was having a complete code block in terms of PHP yesterday, pushing myself to get this project done. I’ve just noticed I didn’t realise there was a numberofposts=5 and with alchymyth’s answer it had an if statement I needed to add.

    This should work for me now,

    much appreciated guys.

    glad to help
