Using check age middleware in Laravel - php

Question

I'm just learning laravel and now i'm stuck at Middleware stuff. I have class AdultMiddleware.php :
<?php
namespace App\Http\Middleware;
use Closure;
class AdultMiddleware
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
if (Session::get('age') < 18) {
return view('search');
}
return $next($request);
}
}
and it's short name in Kernel.php :
protected $routeMiddleware = [
'adult' => \App\Http\Middleware\AdultMiddleware::class,
];
And in web.php :
Route::get('middle', array('as' => 'middle', 'age' => '16', 'before' => 'adult', function()
{
return view('welcome');
}));
As you see in routes I set age as 16 , but still it returns welcome instead of search. What I'm doing wrong? I know it may sound newbie, but I did try to google and had no luck. That's why I'm asking here.

Assigning middleware to a route:
Route::get(..., ['middleware' => 'adult', ...]);
Route::get(..., ...)->middleware('adult');
before is for filters which don't exist any more in Laravel since middleware replaced filters.
Route::get('middle', ['as' => 'middle', 'middleware' => 'adult', function () {
return view('welcome');
}]);

If your middleware is going to check a session variable, you could add a route to be able to set that session variable as you like.
Route::get('set/age/{age}', function ($age) {
session(['age' => $age]);
return redirect()->route('middle');
});
That will set the age variable in the session and redirect you to your 'middle' route.
Also you may want to return a redirect to the search page instead of returning a view from the middleware.
