What happens after a successful user registration in Laravel?

In a typical Laravel registration flow using the built-in Auth scaffolding, what is the default behavior immediately after a user successfully registers?

A The user receives an email with a verification link but stays on the registration page.

B The user is redirected to the login page and must log in manually.

C The user is redirected to the home page and automatically logged in.

D The user is logged out and redirected to a welcome page.

💡 Hint

Think about what Laravel's default Auth::routes() does after registration.

By default, Laravel logs in the user immediately after registration and redirects them to the home page (usually '/home'). This provides a smooth experience where the user doesn't have to log in again.

Identify the correct validation rule for password confirmation in Laravel registration.

Which of the following validation rules correctly ensures that the password confirmation field matches the password field in a Laravel registration controller?

A 'password' => 'required|string|min:8|confirmed'

B 'password' => 'required|string|min:8|same:password_confirmation'

C 'password' => 'required|string|min:8|match:password_confirmation'

D 'password' => 'required|string|min:8|equals:password_confirmation'

💡 Hint

Laravel has a special rule name for confirming passwords.

The 'confirmed' rule automatically checks that the field has a matching field with '_confirmation' appended. So 'password' with 'confirmed' expects a 'password_confirmation' field.

Why does the Laravel registration form not save the user?

Given this simplified registration controller method, why does the user not get saved to the database? public function register(Request $request) { $request->validate([ 'name' => 'required', 'email' => 'required|email|unique:users', 'password' => 'required|confirmed|min:8' ]); $user = new User(); $user->name = $request->name; $user->email = $request->email; $user->password = $request->password; // Missing something here return redirect('/home'); }

Laravel

public function register(Request $request) {
  $request->validate([
    'name' => 'required',
    'email' => 'required|email|unique:users',
    'password' => 'required|confirmed|min:8'
  ]);

  $user = new User();
  $user->name = $request->name;
  $user->email = $request->email;
  $user->password = bcrypt($request->password);
  // Missing something here
  return redirect('/home');
}

A The user object is never saved to the database because $user->save() is missing.

B The password is not hashed before saving, so Laravel rejects saving the user.

C The validation rules are incorrect, so the method exits early without saving.

D The redirect happens before saving, so the save is skipped.

💡 Hint

Check if the user data is actually written to the database.

The code creates a new User object and sets properties but never calls save(). Without calling $user->save(), the user is not stored in the database.

What is the value of $user->email_verified_at after registration with email verification enabled?

In Laravel, when using the built-in email verification feature, what is the value of the email_verified_at field on the user model immediately after registration but before the user clicks the verification link?

A Current timestamp

B null

C Empty string ''

D Boolean false

💡 Hint

Think about when Laravel sets the verification timestamp.

Laravel sets email_verified_at only after the user clicks the verification link. Before that, it remains null.

Which middleware ensures only guests can access the registration page in Laravel?

In Laravel's default registration flow, which middleware is responsible for preventing logged-in users from accessing the registration page?

A auth

B throttle

C verified

D guest

💡 Hint

This middleware checks if the user is NOT logged in.

The guest middleware redirects authenticated users away from routes meant only for guests, such as registration and login pages.
