// Create a new User registration form
public function register(Request $request) { $validatedData = $request->validate([ 'username' => ['required', 'string', 'max:255', 'unique:users'], 'email' => ['required', 'string', 'email', 'max:255', 'unique:users'], 'password' => ['required', 'string', 'min:8', 'confirmed'], ]); $user = User::create([ 'username' => $validatedData['username'], 'email' => $validatedData['email'], 'password' => Hash::make($validatedData['password']), ]); Auth::login($user); return redirect(RouteServiceProvider::HOME); }This code defines a `register` function that handles the POST request from the form. It first validates the incoming data to ensure it meets the necessary requirements (such as a unique username and valid email address). If the data is valid, it creates a new `User` object using Laravel's `create` method, which automatically hashes the password for security. It then logs the user in using Laravel's `Auth` class and redirects them to the home page. In summary, the User register app allows users to create new accounts with a username, email, and password. The app was built using the Laravel package library, which provides built-in authentication and security features.
