Validation 492
Named Error Bags
If you have multiple forms on a single page, you may wish to name the MessageBag of errors,
allowing you to retrieve the error messages for a specific form. Simply pass a name as the second
argument to withErrors:
1 return redirect('register')
2 ->withErrors($validator, 'login');
You may then access the named MessageBag instance from the $errors variable:
1 {{ $errors->login->first('email') }}
After Validation Hook
The validator also allows you to attach callbacks to be run after validation is completed. This allows
you to easily perform further validation and even add more error messages to the message collection.
To get started, use the after method on a validator instance:
1 $validator = Validator::make(...);
2
3 $validator->after(function($validator) {
4 if ($this->somethingElseIsInvalid()) {
5 $validator->errors()->add('field', 'Something is wrong with this field!'\
6 );
7 }
8 });

10 if ($validator->fails()) {
11 //
12 }
Form Request Validation
For more complex validation scenarios, you may wish to create a “form request”. Form requests
are custom request classes that contain validation logic. To create a form request class, use the
make:request Artisan CLI command:
