用于 WooCommerce 管理订单页面的具有多个自定义字段的 Metabox
Metabox with multiple custom fields for WooCommerce admin order pages
前几天我发现了下面的代码,现在我的客户想要两个字段。如果我再次将它添加到我的代码片段插件中,它会显示“无法重新声明函数 set_custom_edit_shop_order_columns”。有人可以帮我用两个自定义字段更改代码吗?
我已将 custom_column 更改为 courier_reference 并想要另一个文本字段 tracking_number,还有一个 shipping_date 带有日期选择器而不是文本框。
感谢任何帮助。

已更新... 您只需要在同一个函数中有多个不同的 slug。对于您想要的 3 个自定义字段,请使用以下内容:
