WooCommerce 产品类别页面为空白

Question

我有一个自定义存档产品模板，用于在商店首页显示带有标题的产品类别。它还允许我从商店页面隐藏某些类别。这些编辑应用于最新版本的archive-product.php。问题是当我转到特定类别页面时，没有显示任何产品，它只是空白。如果我将存档产品模板恢复为默认值，则会填充产品类别页面。下面是添加到模板中的php，是不是好像有什么问题？

谢谢！

 - 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;

                        }
