Laravel redirect with data not working

Since the with method flashes data to the session, you may retrieve the data using the typical Session::get method.

So you have to get as

$message = Session::get('message');

You can use this on your blade template:

@if( Session::has('message') )    <div class="alert alert-success alert-dismissable">        <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>        {{ Session::get('message') }}    </div>@endif

You can check APP/kernel.php and look for this:

\Illuminate\Session\Middleware\StartSession::class,

Check if it is defined more than once like in this example:

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.
