I'm initiating in Laravel.
I searched and not found how to validate data with some ENUM values. On below code I need that typemust be just DEFAULTor SOCIAL. One or other:
我在 Laravel 中启动。我搜索并没有找到如何使用某些 ENUM 值验证数据。在下面的代码中，我需要的type必须是DEFAULT或SOCIAL。一个或另一个：
$validator = Validator::make(Input::only(['username', 'password', 'type']), [
'type' => '', // DEFAULT or SOCIAL values
'username' => 'required|min:6|max:255',
'password' => 'required|min:6|max:255'
]);
Is possible?
有可能吗？

in:DEFAULT,SOCIAL
The field under validation must be included in the given list of values.
in:DEFAULT,SOCIAL
验证字段必须包含在给定的值列表中。
not_in:DEFAULT,SOCIAL
The field under validation must not be included in the given list of values.
not_in:DEFAULT,SOCIAL
验证中的字段不得包含在给定的值列表中。
$validator = Validator::make(Input::only(['username', 'password', 'type']), [

'password' => 'required|min:6|max:255'

The accepted answer is ok, but I want to add how to set the inrule to use existing constants or array of values.
接受的答案是可以的，但我想添加如何设置in规则以使用现有常量或值数组。
So, if You have:
所以，如果你有：
class MyClass {
const DEFAULT = 'default';
const SOCIAL = 'social';
const WHATEVER = 'whatever';
...
You can make a validation rule by using Illuminate\Validation\Rule's inmethod:
您可以使用Illuminate\Validation\Rule'sin方法制定验证规则：
'type' => Rule::in([MyClass::DEFAULT, MyClass::SOCIAL, MyClass::WHATEVER])
Or, if You have those values already grouped in an array, You can do:
或者，如果您已经将这些值分组在一个数组中，您可以执行以下操作：
class MyClass {
const DEFAULT = 'default';
const SOCIAL = 'social';
const WHATEVER = 'whatever';
public static $types = [self::DEFAULT, self::SOCIAL, self::WHATEVER];
and then write the rule as:
然后将规则写为：
'type' => Rule::in(MyClass::$types)
