woocommerce如何根据类别列出购物车中的产品？

Question

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。

车

 Category1

 product name   category       qty    price
 aaa           category1      2      50
 bbb               category1      1       10

Category2

product name   category       qty    price
test1          category2      2      40
test2          category2      1      10     

$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 );

            }

        }
