WooCommerce: Display “Related Product Categories” @ Single Product Page

The WooCommerce Single Product page, on top of letting you add to cart the current item, also displays a list of related products and up-sells (when defined).

But what if you ALSO want to show a grid of “related product categories”, so that the customer can easily navigate to a category page instead of a single (related) product?

In this experiment, we will first calculate the current product’s categories, and then use a WooCommerce shortcode to output them as a grid, right below the related products section. Enjoy!

As this sample product belongs to two categories, the snippet below will show this new “Related Categories” section on the WooCommerce Single Product page.

add_action( 'woocommerce_after_single_product_summary' , 'bbloomer_related_product_cats_single_product', 21 );

function bbloomer_related_product_cats_single_product() {
	global $product;
	$cat_ids = $product->get_category_ids();
	echo '<section class="related categories"><h2>Related Categories</h2>';
	echo do_shortcode( '[product_categories ids="' . implode( ",", $cat_ids ) . '"]' );
	echo '</section>';
}

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
