Laravel simple form not setting errors and session variables - laravel-5

Question

I am new to Laravel and I am trying to create a simple form that adds a record into a database table (that has 2 fields: ID and name).
Here is the code I have so far:
routes.php
Route::group(['middleware' => ['web']], function () {
Route::get('/banks/add', 'BanksController#add');
Route::post('/banks/add', 'BanksController#store');
});
BanksController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Requests\BankFormRequest;
use App\Bank;
class BanksController extends Controller
{
public function add() {
return view('banks.add');
}
public function store(BankFormRequest $request) {
$bank = new Bank(array(
'name' => $request->get('name'),
));
$bank->save();
return redirect('/banks/add')->with('status', 'Your bank has been created! Its name is: '.$request->get('name'));
}
}
BankFormRequest.php
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
class BankFormRequest extends Request
{
public function authorize()
{
return true;
}
public function rules()
{
return [
'name' => 'required|unique:banks|max:255',
];
}
}
Bank.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Bank extends Model
{
public $timestamps = false;
protected $guarded = ['id'];
}
banks/add.php
<form id="registerForm" role="form" method="post">
<pre><?=var_dump($errors)?></pre>
<pre>
<?php if (session()->has('status')): ?>
<?=session('status')?>
<?php endif; ?>
</pre>
<?php if (isset($errors) && $errors->any()): ?>
<?php foreach ($errors->all() as $error): ?>
<p class="alert alert-danger"><?=$erorr?></p>
<?php endforeach; ?>
<?php endif; ?>
<input type="hidden" name="_token" value="<?=csrf_token()?>">
<div class="form-group">
<label>Name</label>
<input type="text" class="form-control" placeholder="Bank name" name="name">
</div>
<button type="submit" class="btn btn-primary">Add</button>
</form>
banks table
CREATE TABLE `banks` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8
In the banks/add view I have the form and 2 var_dumps of the $errors and session('status') variables, but they are always NULL. Otherwise, the form validator works well and it inserts my input into the database if it passes the rules I defined.
Anyone knows what causes my errors to not be shown?

Answer 1

in your banks/add.php
<p class="alert alert-danger"><?=$erorr?></p>
$erorr is wrong

Answer 2

If you are using laravel 5.2 try to remove web middleware on the route group this will fix your problem. why? because the RouteServiceProvider class will add it for you.
line 53 - 60 as of this writing.
protected function mapWebRoutes(Router $router)
{
$router->group([
'namespace' => $this->namespace, 'middleware' => 'web',
], function ($router) {
require app_path('Http/routes.php');
});
}
