WooCommerce: Get Product Parent Categories

Whenever we need to do custom WooCommerce work, remembering how to get “things” is the most time-consuming task. So, a Google search often helps us find the right and quickest solution.

For example, it’s easy to “get the current product’s categories“, but how can we get the “parent product categories” only? In today’s snippet we will see how this can be achieved in 7 lines of PHP. Enjoy!

In this example, the code below would return the IDs of “Business Bloomer Club” and “Clothing” product categories only.

PHP Snippet: Get Current Product’s Parent Categories @ Single Product Page

The PHP below fills the $parent_categories array with parent product category IDs.

 */

$categories = get_the_terms( get_the_ID(), 'product_cat' );
$parent_categories = array();
foreach ( $categories as $category ) {
	if ( $category->parent == 0 ) {
		$parent_categories[] = $category->term_id;
	}
}

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
