WooCommerce: Detect if Current Category Page is a Subcategory

A client of mine had to style a WooCommerce product category page but ONLY if it was a subcategory. So I decided to add a “subcategory” class to the HTML body, so that they could target this in their custom CSS.

As usual, the PHP is quite easy: I check if the current page is a product category, then if the category has “parents” and only in this case add a body class. Pretty easy!

add_filter( 'body_class', 'bbloomer_wc_product_cats_css_body_class' );

function bbloomer_wc_product_cats_css_body_class( $classes ){
if( is_tax( 'product_cat' ) ) {
	$cat = get_queried_object();
	if( 0 < $cat->parent  ) $classes[] = 'subcategory';
return $classes;

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.
