Laravel routing white page with Controller - php

Question

I'm using Laravel 8.
I'm trying to save ip addresses who visited the page. I can save it to the database. But there is a white page problem on page. How can i solve this problem? Thanks.
web.php
Route::get('/', [IpController::class,'addData'], function () {
$slides = App\Slide::all();
$themes = App\Theme::all();
return view('tema.kurumsal.index', compact('slides','themes'));
});
IpController.php
class IpController extends Controller
{
//
function addData(Request $req)
{
$ip = new Ip;
$ip->ip = $req->ip();
$ip->cihaz = $req->userAgent();
$ip->url = $req->getRequestUri();
$ip->save();
}
}

Answer 1

There is no 3rd parameter on Route::get, so what is that function doing ? This is the Source code.
You have a white page because you are not returning a view or data on your IpController.
Have another look at the documentation. There is no 3rd parameter.
Your code should be like this:
Route::get('/', [IpController::class,'addData']);
And your controller:
class IpController extends Controller
{
public function addData(Request $req)
{
$ip = new Ip;
$ip->ip = $req->ip();
$ip->cihaz = $req->userAgent();
$ip->url = $req->getRequestUri();
$ip->save();
$slides = \App\Slide::all();
$themes = \App\Theme::all();
return view('tema.kurumsal.index', compact('slides','themes'));
}
}
