How display value form config table in field of config page of module?

[Trampino]

I created simple module. Everything works ok, except this:
When I enter value to field in modul config form and press Save, than value is saved to database table ps_configuration. But, if I open modul config form once again, than field is empty and value in database table ps_configuration is empty too. Row in table is not deleted, but it is set to empty and I do not know why.

 

There must be some stupid error in my code. But I do not know where. :-(  Can you help me, pleas?

 

Here is code of my methods

 

    public function getContent()
    {
        /**
         * If values have been submitted in the form, process.
         */
        $this->_postProcess();
         $this->context->smarty->assign('module_dir', $this->_path);
         $output = $this->context->smarty->fetch($this->local_path.'views/templates/admin/configure.tpl');
         return $output.$this->renderForm();
    }

    /**
     * Create the form that will be displayed in the configuration of your module.
     */
    protected function renderForm()
    {
        $helper = new HelperForm();

        $helper->identifier = $this->identifier;
        $helper->submit_action = 'submitSDFPFModule';
        $helper->currentIndex = $this->context->link->getAdminLink('AdminModules', false)
            .'&configure='.$this->name.'&tab_module='.$this->tab.'&module_name='.$this->name;
        $helper->token = Tools::getAdminTokenLite('AdminModules');

        $helper->tpl_vars = array(
            'fields_value' => $this->getConfigFormValues(), /* Add values for your inputs */
            'languages' => $this->context->controller->getLanguages(),
            'id_language' => $this->context->language->id,
        );

        return $helper->generateForm(array($this->getConfigForm()));
    }

   protected function getConfigForm()
   {
    return array(
      'form' => array(
      'legend' => array(

      'icon' => 'icon-cogs',
       ),
      'input' => array(
              array(
                        'col' => 3,
            'size' => 3,
            'maxlength' => 3,            
                        'type' => 'text',
                        'prefix' => '<i class="icon icon-envelope"></i>',
                        'desc' => $this->l('Enter seperator'),
                        'name' => 'SDFPF_SEPARATOR',
                        'label' => $this->l('Separator'),
               ),
       ),
      'submit' => array(
      'title' => $this->l('Save'),
      ),
     ),
    );
   }

/**
* Set values for the inputs.
*/
protected function getConfigFormValues()
{
return array(
             'SDFPF_SEPARATOR' => Tools::getValue('SDFPF_SEPARATOR', Configuration::get('SDFPF_SEPARATOR')),

);
}


    /**

    protected function _postProcess()

    }

I still do not know, where is a porblem in my code above. But I soved it by complete remodifying of my code, use this tutorial.
http://doc.prestashop.com/display/PS16/Adding+a+configuration+page

Hi,

This instruction is reposible to set the configuration input value

$helper->fields_value['MYMODULE_INPUT_NAME'] = Configuration::get('MYMODULE_INPUT_NAME');

Hope it helps someone else with same problem.
