return error from form

Your very welcome.

A lot of us on here are using it, I use it with Boilerplate which is AdminLTE 3 backend Dashboard.
and I' am adding my Blog into it now.

Yes I'm getting on with it very well.      Just one question though? 

When I login the user I set additional session data (AuthController::attemptLogin), this works very well.

However, if session expires and user is still logged in ($this->auth->check()) I need to add the additional session data again.

PHP Code:

public function login()
    {
        // No need to show a login form if the user
        // is already logged in.
        
        if ($this->auth->check())
        {    
            //get my data
            //add data to session - this->session->set($data);
            
            
            $redirectURL = session('redirect_url') ?? '/';
            unset($_SESSION['redirect_url']);

            return redirect()->to($redirectURL);
        }

            // Set a return URL if none is specified
            $_SESSION['redirect_url'] = session('redirect_url') ?? previous_url() ?? '/';

        return view($this->config->views['login'], ['config' => $this->config]);
    } 


So I tried to configure a filter to check the session data exists and if not, redirect to login. But I get caught in an infinite loop.

Filter

PHP Code:

public function before(RequestInterface $request) {    
        $auth = service('session');
        $uri = service('uri');;
        
        
            if($uri->getPath!='login' ) 
                        {

                if (!$auth->get('user_id') )
                {
                return redirect('login');
                }
            }
    } 


I'm not sure why because if I type http://mysite/login direct into browser, all is OK

Any ideas?
