Translate validation message in laravel 5

Question

I have a problem translating the laravel messages. I have created a folder called es inside lang folder and I have translated the messages from English to Spanish. Also I have set 'locale' => 'es' on config/app.php. But English messages continues appearing.

I have used the default views for login provided by laravel, to generate it (and routes) I used the command (as says in https://laravel.com/docs/5.2/authentication)

php artisan make:auth

I have changed the default routes by the following:

Route::get('/login', 'UserController@getLogin');
Route::post('/login', 'UserController@postLogin');

And in UserController I have:

public function getLogin(){
    return view('auth.login');
}

public function postLogin(Request $request){
    $input = $request->all();
    if (Auth::attempt(['email' => $input["email"], 'password' => $input["password"]], true))
    {
        return redirect()->intended('/tables');
    }
}

Here are two screenshots of the messages that appears in English

How can I transate these messages?

Thanks

Answer 1

1. Define your language in .env (you can always check what language you are running on with app()->getLocale())
2. Copy resource/lang/validation.php to resources/lang/{YOUR_LANG}/validation.php
3. Find and edit this array:
