easy

Complete the code to check if a user is logged in using Laravel's built-in authentication.

Laravel

<?php
if ([1]) {
    echo 'User is authenticated';
} else {
    echo 'User is not authenticated';
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using auth()->guest() which checks if user is NOT logged in.

Trying to call a method on User model directly.

In Laravel, Auth::check() returns true if the user is logged in.

medium

Complete the code to protect a route so only authenticated users can access it.

Laravel

Route::get('/dashboard', function () {
    return view('dashboard');
})->[1]('auth');

💡 Hint

Common Mistakes

Using guard which is for authentication drivers.

Using non-existent methods like authCheck or secure.

Laravel uses middleware('auth') to restrict routes to authenticated users.

hard

Fix the error in the code to retrieve the authenticated user's email.

Laravel

<?php
$userEmail = [1]->email;
echo $userEmail;

Drag options to blanks, or click blank then click option'

AAuth::user()

BAuth::email()

CUser::email()

Dauth()->email

Attempts:

3 left

💡 Hint

Common Mistakes

Trying to access email directly on auth() or Auth facade.

Using static calls on User model incorrectly.

Auth::user() returns the authenticated user object; then you access email.

4fill in blank

hard

Fill both blanks to create a middleware that redirects guests to login.

Laravel

<?php
public function handle($request, Closure $next)
{
    if ($request->user() [1] null) {
        return redirect()->route([2]);
    }
    return $next($request);
}

Drag options to blanks, or click blank then click option'

A==

B'login'

C!==

D'home'

Attempts:

💡 Hint

Common Mistakes

Using !== which checks for not equal, reversing logic.

Redirecting to 'home' instead of 'login'.

The middleware checks if user is null (not logged in) and redirects to the login route.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps user names to emails for authenticated users only.

Laravel

<?php
$users = User::all();
$result = [];
foreach ($users as $user) {
    if ($user->[1]()) {
        $result[$user->[2]] = $user->[3];
    }
}

Drag options to blanks, or click blank then click option'

AisAuthenticated

Bname

Cemail

DisActive

💡 Hint

Common Mistakes

Using non-existent method isAuthenticated.

Mixing up keys and values in the array.

We check if user is active (authenticated users), then map name to email.
