Laravel MessageBag errors array is empty in view but with content if I kill script
提问by briankip
I am trying to return errors back to my view, this is part of my controller TestcategoryController
我正在尝试将错误返回给我的视图，这是我的控制器 TestcategoryController 的一部分
$rules =array(
'name' => 'required'
);
$validator = Validator::make(Input::all(), $rules);
//process
if($validator->fails()){
return Redirect::to('testcategory/create')->withErrors($validator);
}
In the view testcategory/createif I try and output the errors like
在视图中，testcategory/create如果我尝试输出类似的错误
@if($errors->any())
{{ $errors->first('name') }}
@endif
I get nothing. But if I {{dd($errors)}}I get
我什么也得不到。但如果{{dd($errors)}}我得到
object(Illuminate\Support\ViewErrorBag)#91 (1) { ["bags":protected]=> array(1) {
["default"]=> object(Illuminate\Support\MessageBag)#92 (2)
{ ["messages":protected]=> array(1)
{ ["name"]=> array(1) { [0]=> string(27) "The name field is required." } }
["format":protected]=> string(8) ":message" } } }
The only way I am getting the errors is if I kill the script. What am I doing wrong?
我收到错误的唯一方法是杀死脚本。我究竟做错了什么？

Probably another issue would be with $errors not being saved to Session variable $errors and nothing being shown in the view.
可能另一个问题是 $errors 没有被保存到会话变量 $errors 并且视图中没有显示任何内容。
Here is an example of the same issue: http://laravel.io/forum/03-28-2016-errors-variable-empty-after-failed-validation
这是同一问题的示例：http: //laravel.io/forum/03-28-2016-errors-variable-empty-after-failed-validation
For me the solution defined in the above link worked.
Solution: Is in app\Http\Kernel.php
Move
\Illuminate\Session\Middleware\StartSession::class,from $middlewareGroups to $middleware
对我来说，上面链接中定义的解决方案有效。解决方法：是在 app\Http\Kernel.php\Illuminate\Session\Middleware\StartSession::class,从 $middlewareGroups移动
到 $middleware
Before
前
After

If you get nothing in your case, than it means you have overridden your $errors object with something else or with empty object - check your code and data you pass to the views. Your code is perfectly valid and works good - I've tested it locally. Maybe, you passed empty $errors object to your subview, but in other views the correct object is used.
如果你的情况一无所获，那意味着你已经用其他东西或空对象覆盖了你的 $errors 对象 - 检查你传递给视图的代码和数据。您的代码完全有效并且运行良好 - 我已经在本地对其进行了测试。也许，您将空的 $errors 对象传递给您的子视图，但在其他视图中使用了正确的对象。

Route::group(['middleware' => ['web']], function() {
Route::get('/home', 'HomeController@index')->name('home');
});
Add middleware, and resolved..
添加中间件，并解决..

You need to use it like this:
你需要像这样使用它：
{{ $errors->getBag('default')->first('name') }}
