Prevent overwriting errors message on a page - laravel

Question

I have a page with 2 separated forms, routes and requests.
In this forms I have a field with the same name (for example in each form I have email field).
The problem is when I validating one forms and when form have error, in both forms the error will show.
How can I prevent overwriting errors ?
This is my codes:
Register Request :
class RegisterFormRequest extends FormRequest
{
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'email' => 'required|email|unique:users',
'name' => 'required',
'location' => 'required'
];
}
}
Login Request:
class LoginFormRequest extends FormRequest
{
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'email' => 'required|email',
'password' => 'required'
];
}
}
in blade I use this code above of email field in both forms:
{{$errors->has('email') ? 'has-error' : null }}
When I don't enter email in Login form and submit, the error will show above of email field in Register form too.

Answer 1

Finally I found the solution.
I should add $errorBag variable in Request file:
class RegisterFormRequest extends FormRequest
{
protected $errorBag = 'register';
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'email' => 'required|email|unique:users',
'name' => 'required',
'location' => 'required'
];
}
}
and in blade:
{{$errors->register->has('email') ? 'has-error' : null }}

I have a solution but I am not sure if it is the best way of doing it. The login controller uses the AuthenticatesUsers trait which contains a method sendFailedLoginResponse
By overriding this method in LoginController, you can name the error message bag like this:
protected function sendFailedLoginResponse(Request $request)
{
$errors = [$this->username() => trans('auth.failed')];
if ($request->expectsJson()) {
return response()->json($errors, 422);
}
return redirect()->back()
->withInput($request->only($this->username(), 'remember'))
->withErrors($errors, 'login');
}
Then, in your blade file you can maybe do something like this:
#if (! $errors->login->isEmpty())
<ul>
#foreach ($errors->login->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
#endif
