Hello everyone. I have a little problem with phalcon's flash messages. 1) I've set up flash in DI like so:

    $di->set('flash', function (){
      $flash = new \Phalcon\Flash\Session([

          //tie in with twitter bootstrap classes
          'error'     => 'alert alert-danger',
          'success'   => 'alert alert-success',
          'notice'    => 'alert alert-info',
          'warning'   => 'alert alert-warning'
      ]);
      return $flash;
    });

Then, I am making an redirect if user doesn't have a permission to access particular area.

    if ($allowed != Acl::ALLOW) {
            $this->flash->error("You do not have permission to access this area.");

            $this->response->redirect('site');

        }

And in my view template I try to ouput them like so:

{{ flash.output() }}

When I debugged my code I noticed that in my Permission class (where I handle ACL and redirect) after setting the message it exists, but when I go to a Site controller it dissapears even though it is set in a session. Whats the problem?

Common issue this one. I still have a problem where the CSS dissapears for the flash message. Make sure that you have {{ content() }} in your FINAL rendered view if you are using volt or <?php echo $this->getContent() ?> if you're sticking to the old PHP. There has to be a content() output all the way through any hierarchy; if your are using layouts for instance. In regards to losing styling along the way I had to cheat and put a $this->flash->output(); in the initialize() method of my BaseController.

    <?php

    use Phalcon\Mvc\Controller,
    Phalcon\Tag;

    class BaseController extends Controller {

        /**
        * Main init function
        */
        public function initialize() {
            #code ...
            $this->flash->output();
        }

        #etc etc...
    }

But it is just completely cheating. I have yet to get flash working fully in a within a nice MVC context. :(

Didn't work. The problem is that flash magically dissapears after a redirect, therefore there is nothing to output . Is it a bug?

No it's more of a pain in the arse to get going than a bug. Hanve you got your session set before setting the flash in your injector? Here is mine which is working for me.


    /**
    * Start the session
    */

    $di->set('session', function() {
        $session = new \Phalcon\Session\Adapter\Files();
        $session->start();
        return $session;
    }, true);

    /**
    * Register the flash service with custom CSS classes
    */

    $di->set('flash', function() {
        $flash = new \Phalcon\Flash\Session([
            'error' => 'alert alert-danger',
            'success' => 'alert alert-success',
            'notice' => 'alert alert-info',
        ]);

        return $flash;
    });

See. They advise to disable view rendering.

Your problem is favicon.ico ... probably. Upload it on your server or always return 200 http code in your .htaccess or nginx.conf
