Laravel 5.2 validation check if value is not equal to a variable
提问by patricus
In my instance one user is inviting another I would like to check if the user they are inviting is not themselves.
在我的例子中，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他们自己。
Thus I have two variables incomming emailand user->email
因此我有两个变量传入电子邮件和用户->电子邮件
$this->validate($request, [
'email' => 'required|email',
]);
How can I add that validation rule to the validation call?
如何将该验证规则添加到验证调用中？

You can use not_in, which allows you to specify a list of values to reject:
您可以使用not_in，它允许您指定要拒绝的值列表：
$this->validate($request, [
'email' => 'required|email|not_in:'.$user->email,
]);

You can use different:fieldaccording to the laravel Document
可以different:field根据laravel文档使用
For instanse in your requests validation:
例如在您的请求验证中：
public function rules()
{
return [
'from' => 'required',
'to' => 'required|different:from',
'action' => 'required',
'access' => 'required'
];
}
These two fromand toshould be different(not same).
这两个from和to应该不同（不相同）。
