这是在结帐页面上基于多个单选按钮选择显示隐藏运输方法的正确方法，该方法需要使用PHP，Ajax，jQuery和WC Session。
当 “企业”
单选按钮（默认选项），
flat_rate:3以及
flat_rate:4运输方式将被隐藏，所以客户只能选择
flat_rate:1或
flat_rate:2运输方式。
如果选择了 “住宅”单选按钮
flat_rate:1，
flat_rate:2则将隐藏运输方式，因此客户只能选择
flat_rate:3或
flat_rate:4运输方式。

基于此相关线程的代码：
- 如果在WooCommerce Checkout中选中了“自定义”复选框，则删除运输成本
- 根据WooCommerce结帐字段值显示/隐藏送货方式
