        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 );

            }

        }
