get_meta关于变量签出过程（购物车，签出，电子邮件）

Question

我在Woocommerce中为我的产品创建了一些自定义字段。对于单个产品部件，一切正常。

但是对于可变产品：元信息在产品页面上可见，然后在购物车，结帐和电子邮件中消失。如果有人可以检查我的代码，我将不胜感激:)。

非常感谢。

Answer 1

上面的挂钩并添加产品元数据，以便进一步操作才能在购物车和结帐页面中查看，然后在订单查看页面中必须使用下面的挂钩。

1）用于添加元

add_filter( 'woocommerce_add_cart_item_data', array($this,'addProductToCart' ), 10, 2 );

2）在会话中设置元

add_filter( 'woocommerce_get_cart_item_from_session', array($this, 'get_cart_item_from_session' ), 10, 2);

3）在结帐和购物车页面中检索并显示元数据

 add_filter( 'woocommerce_get_item_data', array($this,'getting_car_item_data' ), 10, 2);
