Why doesn't Laravel 5.3 want to show validation errors?

Question

Laravel

I am learning Laravel. Now I'm analyzing the topic with data validation and I can't display errors.
I created a request class:

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class ContactRequest extends FormRequest
{
    /**
     * 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',
        ];
    }

    public function messages()
    {
       return [
            'name.required' => 'Er, you forgot your name!',
       ];
    }
}

I also created a controller for the page.

namespace App\Http\Controllers\Admin;

use Illuminate\Http\Request;
use App\Http\Requests\ContactRequest;
use App\Http\Controllers\Controller;

use Validator;


class ContactController extends Controller
{
   
    public function store(ContactRequest $request) {
        
        return view('default.contact',['title'=>'Contacts']);
    }
    

    public function show()
    {
        return view('default.contact',['title'=>'Contacts']);
    }

}

I also added the necessary providers to the $middleware property

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

Created 2 routers:

Route::get('/contact',['uses'=>'Admin\[email protected]','as'=>'contact']);
Route::post('/contact',['uses'=>'Admin\[email protected]']);

(I also tried to combine them into the middleware => web group (it didn’t help either))
The form itself looks like this:

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

    <div class="form-area">  
        <form method="post" action="{{ route('contact') }}">
        {{ csrf_field() }}

    				<div class="form-group">
            <input type="text" class="form-control" value="{{ old('name') }}" id="name" name="name" placeholder="Name">
          </div>

          <div class="form-group">
            <input type="text" class="form-control" value="{{ old('email') }}" id="email" name="email" placeholder="Email">
          </div>

          <div class="form-group">
            <input type="text" class="form-control" value="{{ old('site') }}" id="site" name="site" placeholder="site">
          </div>

                    <div class="form-group">
                    <textarea class="form-control" type="textarea" name="text" id="message" placeholder="Message" maxlength="140" rows="7">{{ old('text') }}</textarea>
                        <span class="help-block"><p id="characterLeft" class="help-block ">You have reached the limit</p></span>                    
                    </div>
            
       			 <input type="submit" id="submit" name="submit" class="btn btn-primary">
        </form>
    </div>

But in the end, when submitting the form, no error messages are displayed. Please tell me where to dig? Thank you.

Answer 1

In general, thanks to Arik for help. The problem was to create a session from scratch. That is why the errors were not displayed. I solved the problem by demolishing the framework and installing from scratch.
