WooCommerce: Custom Related Products

WooCommerce picks related products on the Single Product Page based on product categories and/or product tags. Related products are very important to the shopping experience, and sometimes this is not enough – what if you want to automatically show certain products based on different criteria?

So, here’s a quick snippet to e.g. get related products with the same product title of the current one. A very strange example, but you can use this as reference in case you want to get products based on different criteria.

The get_posts() function, in fact, can be customized to get products with a given stock, specific price range, same custom field value, search term, and so on.

In this screenshot, I’m getting Related Products by search title string = “Simple”. All products that include “Simple” in their title will be considered as related.

	$title = $product->get_name();
	$related_posts = get_posts( array(

		'title' => $title,
		'fields' => 'ids',
		'posts_per_page' => -1,
		'exclude' => array( $product_id ),
	));
	return $related_posts;
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101

    I used your snippet to put a related products tab on my product pages, and it worked great for the past two years.

    Now, for some reason, it still appears on the product pages and shows the names of the related products, but no longer the images.

    The links still work to the related products, but none of the related products tabs are showing the images.

    Probably due to some update somewhere.

    Is there any way to code the snippet to show the images?

      Hi Steve! This snippet just gives back a list of post IDs to the code, so images are output later on by WooCommerce itself. Either the returned IDs have no product featured image, or there is a plugin/theme conflict.

      To troubleshoot, disable all plugins but WooCommerce and also switch temporarily to “Twentytwenty” theme (load the snippet there in functions.php) as explained here: https://www.businessbloomer.com/lesson/trwm4l01/

      Once you do that, does it work? If yes, you have a problem with your current theme or one of the plugins.

      Hope this helps!

    Good day. This code helped me a lot – thank you. I have a question. What is it possible for product names to be filtered down to the first “-” (dash) in the product name?

    Rodolfo, can I use this snippet to add similar products, located in nearby regions?

    I am looking for a solution to aggregate products only from certain regions or neighborhoods …

    In this case, you would have to place custom store address fields on each product. Put the city and neighborhood in each product … then search.

    Hello. Your snippet doesn’t work because of ‘title’ argument. You must delete it. Also if someone disable random ordering, it can use add_filter( ‘woocommerce_product_related_posts_shuffle’, ‘__return_false’ ); filter. Thank you.

    Not Working.

    Goodday, I included the snippet as per instruction. However the related products now disappeared completely.
    I am using elementor which is using the standard woocommerce related products.
    Hope you can help

      Hi Stephan, thanks for your comment! This snippets gets Related Products that have the same exact title as the current product – if it finds no products, Related Products will disappear.

      In case you’re looking for other case scenarios, I’m afraid that’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!
