Uploading Files with HelperForm

[orioltestart]

Hi people,

 

I hope you could help me, I need to upload a file (xml) and process it with a module. I've been trying to use the HelperForm creating the form like this:

public function renderForm()
{
  $default_lang = (int)Configuration::get('PS_LANG_DEFAULT');
      $fields_form[0]['form'] = array(
        'legend' => array(
          'title' => $this->l('Importar Productos'),
          'image' => '../img/admin/cog.gif'
        ),
        'input' => array(
          array(
            'type' => 'file',
            'name' => 'my-name',
            'multiple' => false,
            'label' => $this->l('Elija un archivo de importacion'),
            'lang' => true,
            'id' => 'my-name'
          )
        ),
        'submit' => array(
          'title' => $this->l('Guardar'),
          'class' => 'button'
        )
      );

      $token=Tools::getAdminToken($this->className.intval(Tab::getIdFromClassName($this->className)).intval($this->context->cookie->id_employee));
      $helper = new HelperForm();
      $helper->module = $this;
      $helper->name_controller = $this->name;
      $helper->token = $token;
      $helper->currentIndex = AdminController::$currentIndex.'&configure='.$this->name;
      $helper->languages = Language::getLanguages();
      $helper->default_form_language = $default_lang;
      $helper->allow_employee_form_lang = $default_lang;
      $helper->submit_action = 'submit'.$this->name;
      // $helper->fields_value['BETTERPRICE_EMAIL'] = Configuration::get('BETTERPRICE_EMAIL');

      return $helper->generateForm($fields_form);
}

After that I render that form on the template. The question is: where does the file go after the upload? It goes on a controller method? I've tried to override processAdd() and processUpload() with d("HELLO"); and non of those executes that.

 

I have serious doubts about what method executes and when does it on the controller or in the module.php or what where should locate the action of the form -> how does i set the href (on BO the url goes different, what parameters are required..)

 

Hope somebody could help me,

 

Thanks!
