Laravel - extending Illuminate\Http\Request and using session - laravel

Question

I've extended the Illuminate\Http\Request class and am passing it along to my controller.
use Illuminate\Http\Request;
class MyRequest extends Request
{
...
}
Controller
class MyController
{
// Doesnt work
public function something(MyRequest $request) {
var_dump($request->session())
}
// Does work
public function something(Illuminate\Http\Request $request) {
var_dump($request->session())
}
}
So when I'm trying to get session $request->session() I get RuntimeException - Session store not set on request.
I feel it has something to do with not running middlewares on my custom request but I dont know how to make it work. Helping or pionting to the right direction would be much apreciated.
To give a little bit more info. I'm trying to make a wizard. Several pages where content of one page depends on choices on previous pages. I'm storing the data in session and on the final page I do "stuff" with it and clear the session storage of current user.
Because it a lot of lines of code and since session instace lives on request I though it would be elegant to hide all those line it in custom request and in controler simply call $myRequest->storeInputs()
This is what seemed to me as "most elegant" in this particular case so I would prefer to finish it this way but I'm also open to a different solution if there is a better aproach.
Summary: basically where should I hide all those lines which are storing and retriving data from sesison?
Solution: I actually solved it by extending FormRequest since it was solution which was the best fit for what I was trying to do. However I accepted the one offered answer since I believe it is generally better solution and I would use it if not for this very particullar case.

Answer 1

The classic Laravel request already got a bunch of settings you didn't catch on your custom request. To achieve that, you should setup a middleware (maybe global in your use-case) which replaces old request in Laravel's container by yours.
<?php
namespace App\Http\Middleware;
use App\Http\MyRequest;
use Closure;
use Illuminate\Contracts\Foundation\Application;
use Illuminate\Http\Request;
class CustomizeRequest
{
/**
* #var \Illuminate\Contracts\Foundation\Application
*/
protected $app;
/**
* #var \App\Http\MyRequest
*/
protected $myRequest;
/**
* #param \Illuminate\Contracts\Foundation\Application $app
* #param \App\Http\MyRequest $myRequest
*/
public function __construct(Application $app, MyRequest $myRequest)
{
$this->app = $app;
$this->myRequest = $myRequest;
}
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle(Request $request, Closure $next)
{
$this->app->instance(
'request', Request::createFrom($request, $this->myRequest)
);
return $next($this->myRequest);
}
}
