I have some trouble with validation in Laravel 5.2 When i try validate request in controller like this

$this->validate($request, [
                'title' => 'required',
                'content.*.rate' => 'required',
            ]);

Validator catch error, but don't store them to session, so when i'm try to call in template this code

 @if (isset($errors) && count($errors) > 0)
        <div class="alert alert-danger">
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
    @endif

Laravel throw the error

Undefined variable: errors (View: /home/vagrant/Code/os.dev/resources/views/semantic/index.blade.php)

When i'm try validate with this code

 $validator = Validator::make($request->all(), [
                'title' => 'required',
                'content.*.rate' => 'required'
            ]);

            if ($validator->fails()) {
                return redirect()
                    ->back()
                    ->withInput($request->all())
                    ->withErrors($validator, 'error');
            }

Variable $error also not available in template but if i try to display errors in controller

   if ($validator->fails()) {
                dd($validator->errors()->all());
            }

Errors displays but i can't access to them from template.

What's wrong?

Update as of Laravel 5.2.27

Laravel now supports the web middleware by default as you can see here: source

In other words, you no longer need to wrap your routes around the web middleware group because it does it for you in the RouteServiceProvider file. However, if you are using a version of Laravel between 5.2.0 and 5.2.26, then refer to the method below:

Below only applies to Laravel 5.2.0 to 5.2.26

Without seeing your routes.php or Kernel.php file, here is what I suspect is happening.

The way middlewares work has changed from 5.2 and 5.1. In 5.1, you will see this in your app/Http/Kernel.php file:

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

This array is your application's global HTTP middleware stack. In other words, they run on every request. Take a note at this particular middleware: Illuminate\View\Middleware\ShareErrorsFromSession. This is what adds the $errors variable on every request.

However, in 5.2, things have changed to allow for both a web UI and an API within the same application. Now, you will see this in that same file:

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',
    ],
];

The global middleware stack now only checks for maintenance. You now have a middleware group called "web" that includes a bulk of the previous global middleware. Remember that it is like this to allow for both a web UI and an API within the same application.

So how do we get that $errors variable back?

In your routes file, you need to add your routes within the "web" middleware group for you to have access to that $errors variable on every request. Like this:

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

If you aren't going to build an API, another option is to move the "web" middlewares to the global middleware stack like in 5.1.

Laravel 5.2 validation errors, Update as of Laravel 5.2.27. Laravel now supports the web middleware by default as you can see here: source. In other words, you no longer  Displaying The Validation Errors. So, what if the incoming request parameters do not pass the given validation rules? As mentioned previously, Laravel will automatically redirect the user back to their previous location. In addition, all of the validation errors will automatically be flashed to the session.

Try using

return redirect()->back()
              ->withInput($request->all())
              ->withErrors($validator->errors()); // will return only the errors

Validation 5.2 Laravel, When using the validate method during an AJAX request, Laravel will not generate a redirect response. Instead, Laravel generates a JSON response containing all of the validation errors. This JSON response will be sent with a 422 HTTP status code. Catching Laravel Validation Errors in Vue April 07, 2020 / Shane D Rosenthal Validation is a way to ensure that the data submitted from your front end forms or requests meets your expectations and ensures that we are storing the correct data in our database.

I have my working validation code in laravel 5.2 like this

first of all create a function in model like this

In model add this line of code at starting
use Illuminate\Support\Facades\Validator;
public static function validate($input) {

            $rules = array(
                'title' => 'required',
                'content.*.rate' => 'required',
              );
            return Validator::make($input, $rules);
        }

and in controller call this function to validate the input

use Illuminate\Support\Facades\Redirect;
  $validate = ModelName::validate($inputs);
    if ($validate->passes()) {
          ///some code
     }else{
           return Redirect::to('Route/URL')
                            ->withErrors($validate)
                            ->withInput();
      }

Now here comes the template part

@if (count($errors) > 0)
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
and Above all the things you must write your Route like this
Route::group(['middleware' => ['web']], function () {

    Route::resource('RouteURL', 'ControllerName');
});

Laravel - Validation, How do I create a custom validation rule in laravel? I was not able to recreate the problem I encountered with the session data getting reseted randomly on a fresh 5.2 project. Because I have not made a lot of changes to my new project I decided to just start fresh with a new project and not lose anymore time debugging the problems with the old one.

Deep Dive Into Custom Validation Error Messages In Laravel , Can confirm here. I just added my routes to the web middleware and now my error bag is empty even though form validation fails. Laravel 5.2. Remember that we used the @include('common.errors') directive within our view to render the form's validation errors. The common.errors will allow us to easily show validation errors in the same format across all of our pages.

Comments
  • Try "->withErrors($validator, 'error');" without the 'error' so: ->withErrors($validator);
  • in v5.2 you only put Route in to : Route::group(['middleware' => ['web']], function () { // Add your routes here });
  • Indeed, this works! I totally forgot about web middleware!
  • Just as a heads up, if your routes are automatically cached you will need to run php artisan route:clear upon this change.
  • @Dmitry please check this answer as the correct one if it solved your problem, it helps others who come here looking for a solution to the same problem!
  • thanks, that's a better explanation than anything in the documentation. I think the Laravel guys try to be too smart for their own good. I've found 5.2 to be a real pain to understand via the docs.
  • @Ken That will actually not work because "terminatable" middlewares are not supported in the controller. However, there has been a recent change so that web middlewares are supported by default, which I will update in my answer.
  • It would be better if you add a description as to why the latter works and what does middleware vs middlewareGroups. Thanks!
  • I don’t know exactly (I’m new in PHP and Laravel too) but if you take a look in app\Http\Kernel.php the "web" is defined in $middlewareGroups array. I follow a Laravel tutorial and there is used with "middleware" but in my case it function with "middlewareGroups". :o)
  • This works! The clue (I think) is the naming of the protected variables in the app/Http/Kernel. The given by Thomas Kim contains this, but it wasn't clear until I saw this simple snippet. Thanks! This took me hours to fix!
