Controllers & Request Handling

Controllers

Controllers group related request handling logic. Generate with php artisan make:controller.

namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index(): View
    {
        $users = User::all();
        return view("users.index", compact("users"));
    }

    public function store(Request $request): RedirectResponse
    {
        $validated = $request->validate([
            "name" => "required|string|max:255",
            "email" => "required|email|unique:users",
        ]);

        $user = User::create($validated);

        return redirect()->route("users.show", $user);
    }
}

Dependency Injection

use App\Services\UserService;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function __construct(
        private UserService $users,
    ) {}

    public function index(Request $request): View
    {
        $items = $this->users->paginate($request->get("per_page", 15));
        return view("users.index", compact("items"));
    }
}

Response Types

// View responses
return view("greeting", ["name" => "Alice"]);

// JSON responses
return response()->json(["user" => $user]);

// Redirects
return redirect("/home");
return redirect()->route("profile");
return back()->with("status", "Saved!");

// Download responses
return response()->download($pathToFile);
