Common Mistakes

Forgetting to add the colon before the parameter.

    if ($role === 'admin' && $level > 5) {
        return $next($request);
    }

Common Mistakes

Using parameter names that don't match the code logic.

Using generic names like $param when specific names are used.

The middleware parameters are named $role and $level to match usage inside the method.

Laravel

public function handle($request, Closure $next, [1], [2], [3]) {
    if ($role === 'editor' && $status === 'active' && $level >= 3) {
        return $next($request);
    }
    return redirect('login');
}

B$status

C$level

D$user
