Check if Product Belongs to a Product Category or Tag

Are you trying to make it work with in_category() function but nothing happens? Well, in this tutorial you will find out why.

Actually it is a very common mistake and I also did it before.

First things first, let’s begin with the fact that products in WooCommerce are a custom post type product and product categories are a custom taxonomy product_cat. When you work with custom taxonomies, do you use functions for categories/tags or for taxonomies?

Comparing to is_product_category(), WooCommerce doesn’t have its own conditional tags here, so we have to use default WordPress conditional tags like has_term().

has_term( $terms = '', $taxonomy = '', $post = null )

$terms

Pass product category names / slugs or IDs here, you can pass multiple values as an array.

$taxonomy

The second parameter is a taxonomy name, but now we are going to use it for product categories, so set product_cat here. If you want to use it for product tags, just replace it with product_tag.

$post

Product ID or WP_Post object here. If not provided, defaults to the current product in the loop

Now let’s take a look at a couple examples:

if( has_term( 4, 'product_cat' ) ) {
	// do something if current product in the loop is in product category with ID 4
}

if( has_term( array( 'sneakers', 'backpacks' ), 'product_cat', 50 ) {
	// do something if product with ID 50 is either in category "sneakers" or "backpacks"
} else {
	// do something else if it isn't
}

if( has_term( 5, 'product_tag', 971 ) ) {
	// do something if product with ID = 971 has tag with ID = 5
}
