Woocommerce: check if current product is in a child category of 'XXX'

I'm working on WP single.php (woocommerce installed). I need to check if current page is a product page: if yes, also check if this product is in a child category of XXX.

I found this piece of code:

if ( ! function_exists( 'post_is_in_descendant_category' ) ) {
    function post_is_in_descendant_category( $cats, $_post = null ) {
        foreach ( (array) $cats as $cat ) {
            // get_term_children() accepts integer ID only
            $descendants = get_term_children( (int) $cat, 'category' );
            if ( $descendants && in_category( $descendants, $_post ) )
                return true;
        }
        return false;
    }
}

This works perfectly fine on my regular pages, but not on my product pages.

Now I currently use this code:

if ( is_product() && has_term( 'XXX', 'product_cat' ) ) {

The problem is this doesn't check for child categories. Any help?

The function you are using only checks the category taxonomy. use this one on product pages. I've replace 'category' with 'product_cat' and replaced in_category with has_term since that only works on categories

<?php
if (!function_exists('product_is_in_descendant_category')) {
    function product_is_in_descendant_category($cats, $_post = null)
    {
        foreach ((array)$cats as $cat) {
// get_term_children() accepts integer ID only
            $descendants = get_term_children((int)$cat, 'product_cat');
            if ($descendants && has_term($descendants, 'product_cat', $_post)) {
                return true;
            }
        }

        return false;
    }
}

or add a third parameter to the original function that reads $tax = 'category' and replace 'category' with $tax on line 5. then when you call the function on product pages pass 'product_cat' as the third parameter. FYI doing it this way would also require you to replace in_category with has_term
