Laravel 5.2验证检查值是否不等于变量 [英] Laravel 5.2 validation check if value is not equal to a variable

问题描述

在我的情况下，一个用户正在邀请另一个用户，我想检查他们邀请的用户是否不是自己.

In my instance one user is inviting another I would like to check if the user they are inviting is not themselves.

因此，我有两个传入电子邮件和 user-> email

$this->validate($request, [
            'email' => 'required|email',
        ]);

如何将验证规则添加到验证调用中?

How can I add that validation rule to the validation call?

推荐答案

您可以使用not_in，它允许您指定要拒绝的值的列表:

You can use not_in, which allows you to specify a list of values to reject:

$this->validate($request, [
    'email' => 'required|email|not_in:'.$user->email,
]);
