HelperForm hidden input field value

[GS VISION]

Dummy question but I cannot seem to find a straightforward answer. I am building a form using the HelperForm class and I want to pass a hidden field with it for which I use:

		    array(
			'type' => 'hidden',
			'value' => 43,
			'name' => 'id_product'
			),
		   )
		  ); 

Where value seems to invalid key in the array and doesn`t work. I saw the values array but it is said that it is used for radio buttons only.

 

How am I suppose to assign value to the input field?

 

EDIT: Found the solution myself. Inserted this when configuring the helper:

$helper->fields_value['id_product'] = Tools::getValue('id_product');

Hi GS,

I know your post is old but i'm stucked at this point on PS 1.7.6, I built my config form with an hidden field and I cannot find the way to assign him the default value. I tried to add the configuration to the helper but still no success. Do you have any suggestion?

Thanks,

Simone

something like that: (replace yourmodule/YOUR_MODULE_.. with your names)
 

public function switchYesNo($switchName) {
        return  array(
            array(
                'id' => $switchName .'_1',
                'value' => 1,
                'label' => $this->module->l('Enabled')
            ),
            array(
                'id' => $switchName.'_0',
                'value' => 0,
                'label' => $this->module->l('Disabled')
            )
        );
}    

public function processConfiguration()
{
        if (Tools::isSubmit('yourmodule_form'))
        {
            Configuration::updateValue('YOUR_MODULE_VAR1',Tools::getValue('YOUR_MODULE_VAR1',''));     //text
            Configuration::updateValue('YOUR_MODULE_VAR2',(int)Tools::getValue('YOUR_MODULE_VAR1',0));  //switch
            // if you want store default value of hidden field then
            Configuration::updateValue('YOUR_MODULE_VAR3',Tools::getValue('YOUR_MODULE_VAR3',DEFAULT_VALUE_OF_VAR3));  

            $this->context->smarty->assign('confirmation', 'ok');            
        }

}

    {

            array('name' => 'YOUR_MODULE_VAR2', 'label' => $this->module->l('variable2'), , 'type' => 'switch', 'values' => $this->switchYesNo('YOUR_MODULE_VAR2')),

                ),
                'input' => $inputs,
                'submit' => array('title' => $this->module->l('Save'))

            'YOUR_MODULE_VAR3' => (Configuration::get('YOUR_MODULE_VAR3')) ? Configuration::get('YOUR_MODULE_VAR3') : DEFAULT_VALUE_OF_VAR3,
//        ....
          );
            $helper->tpl_vars = array(
            'fields_value' => $helper->fields_value,
            'languages' => $this->context->controller->getLanguages()
        );

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