Question

我必须在我的mysql数据库中使用表格恢复

我正在使用PHP OOP我有这个用户需要填写的 register.php 表单。

我的目标是：

只要位置不发送两次，同一用户就可以提交多个申请。例如“Thomas使用 thomas@mail.com 发送第一个应用程序，ID 1111 ，并将其定位为执行但他不能使用相同的电子邮件地址或身份证号码第二次提交相同的职位“

有人可以帮忙吗？以下是我的代码。 *注意：我在 Check.php 时遇到问题。我不知道如何检查 案例'重复'： 区域。

如果我理解您的问题，user_id不应该是AUTO_INCREMENT。而是创建一个id列作为主键并且是AUTO_INCREMENT：）
