Prestashop Handle post data in custom CMS form

Question

I've developped a prestashop module that display a form, and now I want to use the POST data to store my data in the database.

Following some tutorials I'm able to display the form and load some js file, but my question are two:

What will be the action parameter of my form?
How can i handle the post parameters, and where??

The structure of my module is this - root is /modules/mymodule/ dir:

mymodule.php
/views/templates/hook/mymodule.tpl
/views/js/front.js

Have i to insert a controller??

Thank you.

EDIT- Add some code

mymodule.php

class MyModule extends Module
{
    public function __construct()
    {
        $this->name = 'mymodule';
        $this->controllers = array( 'display' ); // <- my controller name

        parent::__construct();
    }

    public function install()
    {
       if (Shop::isFeatureActive())
         Shop::setContext(Shop::CONTEXT_ALL);

       if (!parent::install() ||
         !$this->registerHook('customCMS') ||
         !$this->registerHook('header')
       )
          return false;

       return true;
     }

    public function hookcustomCMS($params)
    {
        if (Tools::getValue('id_cms') != 7)
            return;

      $this->context->smarty->assign(
          array(
              'form_link' => $this->context->link->getModuleLink('mymodule', 'display')
          )
      );

      return $this->display(__FILE__, 'mymodule.tpl');
    }
}

mymodule.tpl

<form id="myform" action="{$link->getModuleLink('mymodule', 'display')|escape:'html'}" method="post">
<!-- all fields...  + submit button -->
</form>

display.php (this shoul be the controller in mymodule/controllers/front)

<?php
class mymoduledisaplyFrontController extends ModuleFrontController
{


    public function initContent()
    {
        parent::initContent();


        $this->context->controller->addJS($this->module->getLocalPath().'views/js/front.js');
        $this->setTemplate('mymodule.tpl');
    }



    public function postProcess()
    {
      if (Tools::isSubmit('submit_requestform'))
      {
          // form processing

          ppp("OK");


      }
    }

}

That's all...

What is this form? Module configuration? Front page? Admin page? If it's front page or admin page yes you need a controller. You need to provide more information and some code as well so we can help you further. — TheDrot
@TheDrot I've edited the post adding my code. Should be a front controller. My scope is adding a form with some fields and logic and store the data in the database. I've omitted some unuseful code like configs. — Jack
Class declaration of controller is wrong. Look here for proper declaration. — TheDrot
@TheDrot That solved the calling flow. Not I can proceed with my development!! Thank you! — Jack

Please find the answers to your questions below:

What will be the action parameter of my form?

The action parameter for your form will be

$this->smarty->assign('action', 'index.php?controller=AdminModules&token='.Tools::getAdminTokenLite('AdminModules').'&configure='.$this->name)

You need to assign it to smarty from your controller (mymodule.php) in getContent() function and then you can use it as action in your TPL file.

How can I handle the post parameters, and where??

You can get the values of your post parameters in mymodule.php - getContent() function by using the following code:

$post_param = Tools::getValue('name_of_parameter');
