Laravel 5.2 $errors not appearing in Blade

Question

So I'm following along with the Laravel 5 fundamentals tutorial and I am stuck on the form validation. I have followed along exactly with the tutorial but I am getting a Undefined variable: errors in my create articles view.

In the tutorial I am following and what I have found online they say the errors variable is always there in the blade file for you to use so I don't know what i am doing wrong?

Any help would be appreciated! loving Laravel except for this error!

View
    @if($errors->any())
      <ul class="alert alert-danger">
        @foreach($errors->any() as $error)
          <li>{{$error}}</li>
        @endforeach
      </ul>
    @endif

Controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use App\Http\Requests;
use App\Http\Requests\UserRequest as UserRequest;
// use App\Http\Requests\CreateArticleRequest as CreateArticleRequest;
use App\Http\Controllers\Controller;
use Illuminate\View\Middleware\ErrorBinder;

class UserController extends Controller
{
    public function create(){
      return view('pages.signUp');
    }

    public function store(UserRequest $request){
      User::create($request->all());
      return 'the user has been registered!';
      return view('user.profile');
    }

}

Request validation

<?php

namespace App\Http\Requests;

use App\Http\Requests\Request;

class UserRequest extends Request
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'name' => 'required',
            'email' => 'required|email',
            'country' => 'required',
            'password' => 'required|min:6',
            'confirm_password' => 'required|same:password',
            'height' => 'required',
            'weight' => 'required',
        ];
    }
}

Answer 1

This is a breaking problem with the 5.2 upgrade. What's happening is the middleware which is responsible for making that errors variable available to all your views is not being utilized because it was moved from the global middleware to the web middleware group.

There are two ways to fix this:

1. In your kernel.php file, you can move the middleware \Illuminate\View\Middleware\ShareErrorsFromSession::class back to the protected $middleware property.

2. You can wrap all your web routes with a route group and apply the web middleware to them.

   Route::group(['middleware' => 'web'], function() {
       // Place all your web routes here...
   });
   

Answer 2

Solved

You may change any one of the following:

1. put your working route (app/http/routes.php) on

Route::group(['middleware' => ['web']], function () { // Here like Route::get('/', 'TodoController@index'); Route::post('/', 'TodoController@store'); });

2. Move your protected $middlewareGroups web (app/Http/Kernel.php) on protected $middleware = []

Screenshot -

Answer 3

simply, you have to move :

\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,

from protected $middlewareGroups to protected $middleware

Answer 4

This is solution:

Change the defination of your Route groups with a middleware, from :

Route::group(['middleware' => 'web'], function () {

to

Route::group(['middlewareGroups' => 'web'], function () {

Answer 5

1. Just remove , 'middleware' => 'web' from Route::group(array('prefix' => 'user', 'middleware' => 'web'), function() in routes.php page OR

2. Move

   \Illuminate\Session\Middleware\StartSession::class, \Illuminate\View\Middleware\ShareErrorsFromSession::class,

From protected $middlewareGroups to protected $middleware in kernel.php page

As the Laravel Documentation says:

Note: If your copy of Laravel has a RouteServiceProvider that already includes the default routes file within the web middleware group, you do not need to manually add the group to your routes.php file.

So removing from routes.php file would be the correct way.

Answer 6

Posting this as it might be useful for others,

As Smartrahat mentioned in 1st solution, in your Kernel.php file(app/Http/Kernel.php) move \Illuminate\View\Middleware\ShareErrorsFromSession::class from $middlewareGroups to protected $middleware property, but the same will start throwing the error "Session store not set on request",

to resolve this move \Illuminate\Session\Middleware\StartSession::class, to $middleware property as well.

Answer 7

As of 5.2, routes.php is by default already called in the context of a ['middleware'=>'web'] by RouteServiceProvider. But in routes.php default generation of auth routes, the Route::group call is still happening by default - so if you delete that Route::group declaration from routes.php the application then correctly shows errors.

Answer 8

A couple of observations regarding this issue. First off there a related bug in github regarding this issue PFA https://github.com/laravel/framework/issues/12022

If you look at the last comment which Graham wrote, I think that is the facing I was facing. For me even though there was a error in form post data, I was getting the below equality

boolval(count($errors) === 0) === true

In my case I added log statements in the

\Illuminate\Session\Middleware\StartSession::class

the above middleware class ran twice for a given request, I am not sure why it ran twice, but I think because of this the $errors variable is getting reset. I was using this configuration (which I think came default with Laravel@5.2.43)

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
];

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ],

    'api' => [
        'throttle:60,1',
    ],
];

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'can' => \Illuminate\Foundation\Http\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
];

I changed the configuration which worked for me and the $errors variable's count is not zero (also the above middleware ran only once per request)

protected $middleware = [
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
];

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ],

    'api' => [
        'throttle:60,1',
    ],
];

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'can' => \Illuminate\Foundation\Http\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
];

Note: All my routes are in the web middleware group before and after the Kernel.php configuration change, I didnot move my routes at all from the web middleware group.

Answer 9

Change @foreach($errors->any() as $error) to @foreach($errors->all() as $error)

Answer 10

in this case laravel 5.2 you can refer may example code and edit your kernal.php file. move this \Illuminate\View\Middleware\ShareErrorsFromSession::class, form middlewareGroups to middleware and add \Illuminate\Session\Middleware\StartSession::class, to middleware then its work correctly.

Answer 11

Having both Web and API requirements in our application, we did not want to move the middleware around; perhaps that would have worked, however:

We had the very peculiar situation that the flash[] and $errors session data was transmitted correctly between the standard laravel resource methods, store() and edit(), but in some cases the data did not get back across nearly identical methods, storeSale() and editSale().

We found that in our development and deployment environments, the 'file' and 'database' session drivers worked in all cases, but the 'cookie' driver did not.

Switching to the database driver in all instances solved the problem.
