How do I send a form but stay on the same page with phalcon?

Question

In the form I have to define a handler like admin/login . Then it changes the page when I send it. I also tried using public function indexAction() handler and only using the controller admin without a handler, but then nothing happens.

Any help would be greatly appreciated.

Edit:
I wanted to have a error message but it was not so big a site that i wanted to make a form class.

The way i eventually fixed it was the following:

First i use $this->view->pick('admin/index'); in the handler to select my old view.
Next i send a variable like a error message with $this->view->setVars(['username' => $user->name,]); in the handler.
Last i used it with volt in the previous view views/admin/index.phtml like this {{ username }}

If you are using a form object you can then use the following code in your volt template

{{ form('myform', 'method':'post', 'role': 'form') }}

This will post your data to the same controller/action that invoked the form. From then you will be able to handle the posted data using valid() in the form as well as request->isPost()
