我正在使用带有wordpress的woocommerce . 我需要按类别在购物车中展示产品 . 如果用户从category1中选择一个产品并添加到购物车，然后从category2中添加购物车中的产品，然后再添加category1中的任何其他产品 . 然后我需要category1的产品，然后是category2 . 我需要在购物车中以这种方式显示产品 . 我正在尝试更改cart.php文件中的代码 .

$taxonomies = get_terms( array(
            'taxonomy' => 'product-cat',
            'hide_empty' => false,
        ) );

        foreach ( $taxonomies as $_tax ) 
        {
             $allfactories[] = $_tax->name;
        }




        foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {

            //print_r($cart_item);

            $cart_cat = $cart_item['wdm_user_custom_data_value'];

            $terms = wp_get_object_terms($cart_item['product_id'], 'product-cat');
            foreach ($terms as $term) {
               $product_cat = $term->name;
               $factory[]  = $term->name;
            }

            if($product_cat==$cart_cat)
            {

            $_product     = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
            $product_id   = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );
