Laravel Cant pass error validation to blade

Question

I'm using chatter package for Laravel. but when there is an error while validating. there is no error bag send to the blade. this is the code:

  $validator = Validator::make($request->all(), [
        'title'               => 'required|min:5|max:255',
        'body_content'        => 'required|min:10',
        'chatter_category_id' => 'required',
    ]);

    if ($validator->fails()) {

        return back()->withErrors($validator)->withInput();
    }

blade:

@if (count($errors) > 0)
    <div class="chatter-alert alert alert-danger">
        <div class="container">
            <p><strong><i class="chatter-alert-danger"></i> {{ Config::get('chatter.alert_messages.danger') }}</strong> Please fix the following errors:</p>
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
    </div>
@endif

kernel:

  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,

];

every time I'm trying to dd the $errors in the blade, there is always empty bag.
Note: every validation working fine, but not this one

Answer 1

Comment this out

 // \Illuminate\Session\Middleware\StartSession::class,

And make sure you have a web middleware in your routes.

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

try this one dude.

controller

$this->validate(
            $request,
            [
                'title'               => 'required|min:5|max:255',
                'body_content'        => 'required|min:10',
                'chatter_category_id' => 'required',
            ]
        );

if validate is fail it automatically return back to your previous view.

View

@if (count($errors) > 0)
    <div class="chatter-alert alert alert-danger">
        <div class="container">
            <p><strong><i class="chatter-alert-danger"></i> {{ Config::get('chatter.alert_messages.danger') }}</strong> Please fix the following errors:</p>
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
    </div>
@endif
