💡 Hint

Common Mistakes

Returning $request directly instead of calling $next.

Calling a function named 'next' without the $ sign.

You must call the Closure $next with the $request to pass the request to the next middleware or controller.

Fix the error in the middleware to block users under 18 years old.

Laravel

public function handle($request, Closure $next) {
    if ($request->age [1] 18) {
        return redirect('home');
    }
    return $next($request);
}

💡 Hint

Common Mistakes

Using '>=' which allows underage users.

Using '==' which only blocks exactly 18.

To block users under 18, check if age is less than 18.

Fill both blanks to create middleware that adds a header and passes the request.

Laravel

public function handle($request, Closure [1]) {
    $response = [2]($request);
    $response->headers->set('X-Custom-Header', 'MyValue');
    return $response;
}

💡 Hint

Common Mistakes

Using 'next' without $ sign.

Using $response as the Closure parameter.

The Closure parameter is $next and you call $next($request) to get the response.

Fill all three blanks to create middleware that checks a user role and redirects if unauthorized.

Laravel

public function handle($request, Closure [1]) {
    if ($request->user()->role [2] 'admin') {
        return [3]($request);
    }
    return redirect('unauthorized');
}
