使用laravel框架的视图中的var $ errors

Question

i use the validated method for validate request, but the var errors is empty in the view :/.

in the controller, i have:

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

Route::get('/', function(){
    return view('home'); 
})->name('home'); 

Route::group(['prefix' => 'do'], function($name = null){


Route::get('/{action}/{name?}', ['uses' => 'controllers@get', 'as' =>                                                                  'get']); 


    Route::post('/', ['uses' => 'controllers@post', 'as' => 'post' ]);

    });
});

for the controller, i have:

<?php namespace App\Http\Controllers;

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


class controllers extends Controller
 {

  public function get($action, $name=null)
  {
   return view('actions.' . $action, ['name' => $name]);

  } 

  public function post(Request $request)
  {


 $this->validate($request, [
     'action' => 'required',
     'name' => 'alpha|required'
 ]);

 return view('actions.'.$request['action'] , ['action' =>        $request['action'], 'name'=>$this->transformName($request['name'])]);  
}

private function transformName($name)
{
  $add = "king ";
   return $add.strtoupper($name);
 }
}

and for the view, i have:

@extends('layouts.master')

@section('content')
    <div class="centered">
        <a href="{{route('get', ['action' => 'greet'])}}">greet</a> 
        <a href="{{route('get', ['action' => 'hug'])}}">hug</a>
        <a href="{{route('get', ['action' => 'kiss'])}}">kiss</a>
        <br >
        <br >
         @if (isset($errors) && count($errors) > 0)
       <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                {!! $errors->first() !!}
            @endforeach
        </ul>
    </div>
        @endif      
        <form action="{{ route('post')}}" method="post">
            <label for="select-action">I want to...</label>
            <select id="select-action" name="action">  
                <option value="greet">greet</option>
                <option value="hug">hug</option>
                <option value="kiss">kiss</option>
            </select>
            <input type="text" name="name"> 
            <button type="submit">action</button>
            <input type="hidden" name="_token" value="{{Session::token()}}"> 
        </form>
    </div>
   @endsection

if i delete the middleware of the route, the var errors work correctly.

how i can fix this?

thanks.

If you're using latest Laravel 5.2 build, you should remove web middleware from routes. Now it applies automatically to all routes and if you're trying to add it manually, it causes different errors.
