【问题描述】：
最近几天，我遇到了一个问题。验证错误变量在刀片文件中为空..我是 在 Laravel 5.2.45 中开发多语言应用程序。因此，它们中的每一个都有验证错误消息（resources/lang/{locale}/validation.php）。
验证规则位于包含验证规则并将授权声明为 true 的请求文件（例如 ValidateUserRequest）中。然后我将它传递给控制器。 Bellow 是我的中间件和路由文件的一部分。
任何帮助将不胜感激
内核.php
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',
],
];
protected $routeMiddleware = [
'auth_pabl' => \App\Http\Middleware\AuthenticateBackEnd::class,
'auth' => \App\Http\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
'can' => \Illuminate\Foundation\Http\Middleware\Authorize::class,
'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
];
routes.php（Admin 目录内的所有控制器）
Route::auth();
Route::group ( [
'namespace' => 'Admin'
],
function () {
Route::get ( 'admin/dashboard', [
'uses' => 'PanelController@dashboard',
'as' => 'admin.dashboard'
] );
/*
* Authors
*/
Route::get ( 'admin/authors', [
'uses' => 'PanelController@authors',
'as' => 'admin.authors'
] );
Route::post ( 'admin/authors', [
'uses' => 'AuthorController@store',
'as' => 'admin.authors.store'
] );
Route::get ( 'admin/authors/{slug}/edit', [
'uses' => 'AuthorController@edit',
'as' => 'admin.authors.edit'
] );
Route::post ( 'admin/authors/{username}/edit', [
'uses' => 'AuthorController@update',
'as' => 'admin.authors.update'
] );
Route::get ( 'admin/authors/{username}/delete', [
'uses' => 'AuthorController@delete',
'as' => 'admin.authors.delete'
] );
会话消息通常来自类似
\Session::flash('flash_contact', 'Success. Data stored');
return redirect()->route('admin.events.create');
它是（不）显示与
@if($errors->count()>0) <br /> <br />
<div id="#problem" class="alert alert-danger text-pull-left">
<p>{!! trans('admin/form/placeholders.errors') !!}</p>
<ul class="errors">
@foreach($errors->all() as $error)
<li>{{$error}}</li>
@endforeach
</ul>
</div>
@endif
@if(Session::has('flash_contact'))
<div id="success" class="alert alert-success text-center">
{{Session::get('flash_contact')}}
</div>
@endif
最后 php artisan route:list 表明存在“web”中间件（我没有手动声明两次）
//编辑 1（withErrors from controller）
请注意，withErrors 函数都没有给我预期的结果。下面是我的控制器的一部分。
public function store(Requests\ValidateEventsRequest $request)
{
try {
return $this->dbEvent->add($request);
} catch (\Exception $e) {
return redirect()->to('/admin/events/add')->withErrors('Error
detected');
}
}
//编辑 2
这不应该工作吗？？？
Route::get('flash', function () {
return redirect()->to('flash2')->withErrors('Where are my errors?');
});
Route::get('flash2', function () {
return view('flash2');
});
还有我的 flash2.blade.php
<html>
<body>
@if($errors->count()>0) <br /> <br />
<div id="#problem" class="alert alert-danger text-pull-left">
<p>{!! trans('admin/form/placeholders.errors') !!}</p>
<ul class="errors">
@foreach($errors->all() as $error)
<li>{{$error}}</li>
@endforeach
</ul>
</div>
@endif
this is my flash page
</body>
</html>
【问题讨论】：
-
你试过转储错误吗？有可能没有错误..
-
@loannisKaragiannis。我认为这可能是您的解决方案：stackoverflow.com/a/36691774/5704410
-
不幸的是没有.. $errors 仍然是空的。 protected 'bags' => array (size=0) empty 。另外，web 中间件现在通过了两次，在我的 route:list
-
@flex_ 倾倒错误给我一个空包
-
@OmisakinOluwatobi 你能看看Edit 2..吗？即使是这个简单的测试也没有按预期返回我的 $errors
