WooCommerce 从购物车中删除所有产品并将当前产品添加到购物车
问题描述：
我是 WooCommerce 的新手，我只需要在购物车中添加一个产品.当我点击添加到购物车"按钮时，我想清除所有产品并将当前产品添加到购物车.
I am new to WooCommerce and I need to be able to only add one single product in the cart. I want to clear all products and add the current product to the cart when I click the "Add to cart" button.
我该怎么做?
答
试试这个，
//For removing all the items from the cart
global $woocommerce;
$woocommerce->cart->empty_cart();
$woocommerce->cart->add_to_cart($product_id,$qty);
类文件是 wp-content/plugins/woocommerce/classes/class-wc-cart.php
希望它有所帮助..
