php - laravel route callback return controller

one text

Solution:

First things first,

Since you are returning from an if statement, no else is required

This

Route::get('/home', function () {
    if (session()->has('username')) return view('home');
    else return redirect('/');
});

Should look like this;

Route::get('/home', function () {
    if (session()->has('username')) {
        return view('home');
    }

    return redirect('/');
});

Second, dont worry about all that if else inside of the route and just pass it to your controller, throw a route middleware on it. Below is the basic auth middleware but you can also create your own

use App\Http\Controllers\UserController;

Route::get('/home', [HomeController::class, 'index'])->middleware('auth');
