Cart空在添加到cart方法之后

Question

我正在为WC可变产品开发一个功能。这将是与不同的“等级”的门票，为每一级另一个价格。用户应该选择他想要的门票数量，在创建该表单之后，他可以为每一张票(行)添加名称、地址和票务级别。所有这些数据都应该是发送到购物车并按顺序保存的数据。

又是你们好。

我花了更多的时间在这个问题上，并更进一步。

我几乎做了我想做的事：

1. 用户可以选择票号
2. 用户可以为每个票证(名称、地址、bio、票务级别)填写附加信息--
3. --所有这些行都将被添加到cart
4. 中，所有这些数据都显示在购物车中，结帐

<代码>H 111>所有这些数据都将发送到订单/电子邮件H 212G 213。

现在我发现了问题(当然，可能还有更多的问题)。但是，我一直在做这件事，就像在同一个浏览器窗口中记录用户一样。之后，我意识到，当我使用inkognito模式，或其他浏览器没有会话或此网站的cookie存储，添加项目后，购物车是空的。

当我第一次尝试添加一些其他项目，即使用常规WC添加到购物车按钮，这是有效的，然后我可以添加我的票，没有问题。

但是当我先加票的时候，购物车是空的。在我的主浏览器中，作为日志用户，我没有问题。

我对此做了一些研究，但我只是在尝试。我真的不明白这个问题，所以我又在浪费时间了。

如果有人能帮助我或引导我找到解决方案，我会很高兴的。

谢谢您抽时间见我。

用这个答案解决：https://stackoverflow.com/a/53422060/12897376

当未登录时，您需要启动Woocommerce用户会话。因此，您将使用以下内容：

add_action( 'woocommerce_init', 'force_non_logged_user_wc_session' );
function force_non_logged_user_wc_session(){ 
    if( is_user_logged_in() || is_admin() )
       return;

    if ( ! WC()->session->has_session() ) 
       WC()->session->set_customer_session_cookie( true ); 
}

非常感谢。
