Laravel验证器在重定向后不显示消息？

Question

我所做的很基本。在重定向之前我可以看到我的验证错误，所以我认为我已经覆盖了会话（我不这样做）或从视图中删除某些东西，这也是没有意义的，因为验证器适用于我的\ Auth \ register但没有其他行动。

这是我有：

在\软件\ \控制器QuestionsController

QuestionsController extends Controller{ 
protected$rules=[ 
    'question'=>array(
     'text'=>'required|max:2000', 
     'categories'=>'required|min:4' 
    ) 
]; 

public function create(Request $request){ 

    $valid=Validator::make($request->all(),$this->rules['question']); 

    if($valid->fails()){ 
     var_dump($valid->messages());//exit; 
     return redirect('/questions')->withErrors($valid,'questions'); 
    } 
    //...additional adding scripts etc... 
} 

现在，这是重定向我可以看到我的消息之前！

现在你会觉得我傻，而不是使用名称的袋子或东西，但即使我删除名称袋我没有看到消息：•

在我question.add鉴于

@import('defaults.errors',['sub'=>'questions']) 
{{var_dump(count($errors))}} 
{{var_dump($errors->questions)}} 

在defaults.errors

@if(isset($sub)) 
    @if(count($errors->$sub)>0) 
     <div class="alert alert-danger"> 
      <ul class='nav'> 
       @foreach($errors->$sub->all() as $error) 
        <li><span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span> {{ $error }}</li> 
       @endforeach 
      </ul> 
     </div> 
    @endif 
@else 
    @if(count($errors)>0) 
     <div class="alert alert-danger"> 
      <ul class='nav'> 
       @foreach($errors->all() as $error) 
        <li><span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span> {{ $error }}</li> 
       @endforeach 
      </ul> 
     </div> 
    @endif 
@endif 

我想，也许是因为我不明白Laravel那么好，也许我已经“覆盖”事做在我的控制器的$错误或会话？

这是我的控制器看起来像

<?php 

namespace App\Http\Controllers; 

use Illuminate\Foundation\Bus\DispatchesJobs; 
use Illuminate\Routing\Controller as BaseController; 
use Illuminate\Foundation\Validation\ValidatesRequests; 
use Illuminate\Foundation\Auth\Access\AuthorizesRequests; 
use Illuminate\Foundation\Auth\Access\AuthorizesResources; 
use Auth; 

use App\conversation; 
use App\notifications; 
use App\relationships; 
use App\Helpers\DatetimeHelper; 

use Azza\Utilities\NumberSuffix; 


class Controller extends BaseController 
{ 
    public $user; 
    public $title=array('title'); 
    public $titleSeperator=' - '; 
    public $keywords=array('hello','I added'); 
    public $messageCount=0; 
    public$notifications=null; 
    public$notificationsCount=0; 
    public$friendRequests=0; 
    public$bodyClass=array(); 

    use AuthorizesRequests, AuthorizesResources, DispatchesJobs, ValidatesRequests; 

    public function __construct(){ 
     $this->user=Auth::user(); 
     if($this->user){ 
      $this->messageCount=conversation::getByUserId($this->user->id)->countUnseen()->count(); 
      //$this->notifications=notifications::getByUserId($this->user->id)->get()->paginate(5); 
      $this->notificationsCount=notifications::getByUserId($this->user->id)->countUnseen()->count(); 
      //var_dump($this->messageCount->count());exit; 
      $this->friendRequests=relationships::countRequests($this->user->id)->count(); 
     } 
     view()->composer('*',function($view){ 
      $view->with('currentUser',$this->user); 
      $view->with('title',$this->title); 
      $view->with('titleSeperator',$this->titleSeperator); 
      $view->with('keywords',$this->keywords); 
      $view->with('messageCount',$this->messageCount); 
      $view->with('notificationsCount',$this->notificationsCount); 
      $view->with('friendRequests',$this->friendRequests); 
      $view->with('DatetimeHelper',new DatetimeHelper()); 
      $view->with('NumberSuffix',new NumberSuffix()); 
      $view->with('bodyClass',implode(' ',$this->bodyClass)); 
     }); 
    } 
    public function setDefaultVals($name,$val){ 
     view()->composer('*',function($view) use($name,$val){ 
      $view->with($name,$val); 
     }); 
    } 
} 

这样做是为了刚刚腾出时间操控着我的头信息，并使用动态数组数据的基本思想。我知道这看起来很混乱，可能不是最好的方式，但我现在只是在搞laravel。

我已经设置了你的代码在我的Laravel的环境中，你正在做的一切都是正确的。但是，在5.2 laravel的中间件中作用稍有不同，您的$errors变量仅在中间件活动的StartSession时才可用。

你Kernel.php会这个样子，或类似：

/** 
    * The application's global HTTP middleware stack. 
    * 
    * These middleware are run during every request to your application. 
    * 
    * @var array 
    */ 
    protected $middleware = [ 
     \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class, 
    ]; 

    /** 
    * The application's route middleware groups. 
    * 
    * @var array 
    */ 
    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', 
     ], 
    ]; 

尝试将其更改为这样：

/** 
    * The application's global HTTP middleware stack. 
    * 
    * These middleware are run during every request to your application. 
    * 
    * @var array 
    */ 
    protected $middleware = [ 
     \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class, 
     \Illuminate\Session\Middleware\StartSession::class, 
    ]; 

    /** 
    * The application's route middleware groups. 
    * 
    * @var array 
    */ 
    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', 
     ], 
    ]; 

通知上\Illuminate\Session\Middleware\StartSession::class

尝试

return redirect('/questions')->withErrors($valid->messages());
