我正try 在WooCommerce checkout 的顶部放置两个自定义域(理想情况下是购物车页面，但我在网上找不到任何关于这一可能性的内容)
我有两个自定义字段出现在 checkout 页面上，但由于php知识非常有限，我试图创建一个下拉菜单等.表面上看起来一切都很好.这些字段显示在 checkout 页面上，但每当我输入信息并try 继续进行订单以测试这些值是否显示在感谢页面和邮箱上时，系统会要求我在这些必填字段中填写信息.出于某种原因，页面无法识别这些字段为空
我用的是这个post...https://www.businessbloomer.com/woocommerce-add-custom-checkout-field-php/
但我不得不对它进行了相当多的编辑，才走到了这一步.我相信这里面肯定有很多错误.
