Add error to validation errors using formRequest - laravel

Question

i'm trying to figure out how to add a error message to the default $error generated by the Illuminate\Support\MessageBag when using validation trough requests.
I've searched on google and the laravel docs and not really found information clarifying this for me.
AuthController
<?php
namespace App\Http\Controllers\Auth;
use Auth;
use App\User;
use App\Http\Requests\LoginFormRequest;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
/*
* AuthController
*/
class AuthController extends Controller {
/*
* Create view
*
* #return View
*/
public function getLogin() {
return view('auth.login');
}
/*
* Validate Login
*
* #return Redirect route
*/
public function postLogin(LoginFormRequest $request) {
if (Auth::attempt(array('email' => $request->email, 'password' => $request->password), $request->remember)) {
return redirect()->intended('home')->with('success-message', 'Succesfully authenticated');
} else {
$validator->addMessage('Incorrect email and password combination');
return redirect('account.login')->withErrors($validator)->withInput();
}
}
}
LoginFormRequest
<?php
namespace App\Http\Requests;
use Response;
use Illuminate\Foundation\Http\FormRequest;
class LoginFormRequest extends FormRequest {
public function rules() {
return array(
'email' => 'required|email',
'password' => 'required|between:8,20'
);
}
public function authorize() {
return true;
}
}
Hopefully someone has encountered this problem before and can help me!

Answer 1

Just add the messsages() function to your LoginFormRequest class:
public function messages()
{
return array(
'email.required' => 'The email address is required.',
'password.required' => 'The password is required.',
'password.between' => 'The password should be between 8 and 20 characters.',
);
}
Using the dot notation, you specify the field first and then the type of validator.

Answer 2

$validator->getMessageBag()->add("password", "Username and/or password don't match.");
Will add an error for this field.
