Laravel redirect with data not working
提问by Kuurde
My application is a simple CRUD application. I have a delete controller action which redirects back to the list when the item is successfully deleted. What I'm trying to add now is a message to the user that the data was successfully deleted.
我的应用程序是一个简单的 CRUD 应用程序。我有一个删除控制器操作，当项目成功删除时，它会重定向回列表。我现在要添加的是一条消息，告诉用户数据已成功删除。
My Controller Action:
我的控制器操作：
public function deleteItem($id)
{
try {
$item = Item::findOrFail($id);
$item->delete();
return Redirect::to('list')->with('message', 'Successfully deleted');
} catch (ModelNotFoundException $e) {
return View::make('errors.missing');
}
}
The part of my list.blade.php view where I try to display the message:
我尝试显示消息的 list.blade.php 视图部分：
@if (isset($message))
<div class="alert alert-success alert-dismissable">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
{{ $message }}
</div>
@endif
The problem that I have is that the $messagevariable is always empty ..
我遇到的问题是$message变量总是空的..

Since the with method flashes data to the session, you may retrieve the data using the typical Session::getmethod.
由于 with 方法将数据闪存到会话中，因此您可以使用典型Session::get方法检索数据。
So you have to get as
所以你必须得到
$message = Session::get('message');

You can use this on your blade template:
您可以在刀片模板上使用它：
@if( Session::has('message') )
<div class="alert alert-success alert-dismissable">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
{{ Session::get('message') }}
</div>
@endif

You can check APP/kernel.php and look for this:
您可以检查 APP/kernel.php 并查找：
\Illuminate\Session\Middleware\StartSession::class,
Check if it is defined more than once like in this example:
检查它是否像本例中一样被多次定义：
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\Illuminate\Session\Middleware\StartSession::class,
];
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,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],
You can comment any one of the two or delete it. We need to define it one time only.
您可以评论两者中的任何一个或将其删除。我们只需要定义一次。
