Woocommerce：覆盖现有电子邮件所需的登录。将订单添加到用户帐户

电子商务设置：

• 来宾结账已禁用
• 启用签出期间创建帐户（用户和passowrd自动生成）

如果用户已注册。但没有登录。 使用签出错误 “已使用您的电子邮件地址注册了一个帐户。请登录。”

如何将此重写为 完成订单，并将订单绑定到现有帐户。 提示用户下次登录以加快签出速度

找不到任何可以执行此操作的代码段或模块

还没有。乐意报答

这个没有钩子。您可能需要修改WC core（plugins/woocommerce/includes/class WC checkout.php）行#935中的process_customer函数-请记住，不鼓励编辑core（更新后，您的更改将丢失）

如果您已启用“允许客户在签出时登录”，则会出现“从签出页面登录”选项
