WooCommerce产品类别页面为空白

Question

I have a custom archive-product template for displaying my product categories with headers in the shop front page. It also allows me to hide certain categories from the shop page. These edits were applied to the newest version of the archive-product.php. The problem is that when I go to the specific category page, no products are shown, it is just blank. If I revert the archive-product template back to default, the product category pages are then populated. Below is the php added to the template, is there something that seems to be wrong with it?

Thanks!

 - Try using following code and let me know if it works


                $obj           = get_queried_object();

                        if(is_shop()){
                            $parent_id  = empty( $obj->parent  ) ? 0 : $obj->parent;
                        }else if(is_product_category()){
                            $obj  = get_queried_object();
                            $parent_id  = empty( $obj->term_id  ) ? 0 : $obj->term_id; 
                            $cat_slug   = empty( $obj->slug  ) ? 0 : $obj->slug;
