[SOLVED] helperform variable error

[Rhobur]

Hi,

Can someone see what I can't see?

I have this code in a module.

Nothing seems to be wrong, but I the form doesn't display, I get the error:

Undefined variable: fields_form 

The code is bellow:

	public function renderForm(){

		$this->fields_form = array(
			'legend' => array(
			  'title' => $this->l('Configurare variabile API'),
			  'image' => '../modules/rca/images/logo_stores.png',
			),
			'input' => array(
		    array(
					'label' => $this->l('RCA user name'),
		      'type' => 'text',
		      'name' => 'rca_user_name'
		     ),
				 array(
 					'label' => $this->l('RCA password'),
 		      'type' => 'text',
 		      'name' => 'rca_password'
 		     ),
				 array(
 					'label' => $this->l('URL token RCA'),
 		      'type' => 'text',
 		      'name' => 'url_token_rca',
					'desc' => $this->l('URL to get the authentification token.')
 		     ),
				 array(
 					'label' => $this->l('URL cotatie RCA'),
 		      'type' => 'text',
 		      'name' => 'url_quote_rca',
					'desc' => $this->l('URL to get the RCA quote.')
 		     ),
				 array(
 					'label' => $this->l('URL oferta RCA'),
 		      'type' => 'text',
 		      'name' => 'url_offer_rca',
					'desc' => $this->l('URL to get the RCA offer.')
 		     ),
				 array(
 					'label' => $this->l('URL comanda RCA'),
 		      'type' => 'text',
 		      'name' => 'url_order_rca',
					'desc' => $this->l('URL to order the RCA.')
 		     ),
				 array(
 					'label' => $this->l('Username evignettes'),
 		      'type' => 'text',
 		      'name' => 'user_name_rov'
 		     ),
				 array(
 					'label' => $this->l('Authentification key Evignettes'),
 		      'type' => 'text',
 		      'name' => 'auth_key_rov',
					'desc' => $this->l('Add the authentification key to access the evignettes API.')
 		     ),
		  ),
		  'submit' => array(
		    'title' => $this->l('Save'),
		    'class' => 'btn btn-default pull-right'
		  )
		);
		$helper = new HelperForm();
		$helper->module = $this;
		$helper->table = 'rca';
		$helper->default_form_language = (int)Configuration::get('PS_LANG_DEFAULT');
		$helper->allow_employee_form_lang = (int)Configuration::get('PS_BO_ALLOW_EMPLOYEE_FORM_LANG');
		$helper->submit_action = 'rca_form';
		$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' => array(
			'rca_user_name' => Tools::getValue('rca_user_name',	Configuration::get('RCA_USER')),
			'url_token_rca' => Tools::getValue('url_token_rca',	Configuration::get('RCA_TOKEN')),
			'url_quote_rca' => Tools::getValue('url_quote_rca',	Configuration::get('RCA_QUOTE_URL')),
			'url_offer_rca' => Tools::getValue('url_offer_rca',	Configuration::get('RCA_OFFER_URL')),
			'url_order_rca' => Tools::getValue('url_order_rca',	Configuration::get('RCA_ORDER_URL')),
			'user_name_rov' => Tools::getValue('user_name_rov',	Configuration::get('ROV_USER')),
			'auth_key_rov' => Tools::getValue('auth_key_rov',	Configuration::get('ROV_KEY'))
		),
		'languages' => $this->context->controller->getLanguages()
	);

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

	}

use:

		$fields_form = array(
			'form' => array(

if you look at native modules you will find good examples on usage.  I will say however that 'helper' is a funny name for something so cumbersome to use.

Thank you El Patron, you're a life saver!

Care to explain what was this necessary?

In the book and every example  I found the

$this->fields_form = array(

was the default.

Before asking here I even tried 

$fields_form[0]['form]

with no luck.

I typically will just search native for examples that I know work.  I miss the days one could be forms with say dreamweaver or spry assets, building arrays to build a  form is 'very' difficult....I don't know if ps developers have some WYSIWYG form builder that works with helper concept...honestly I roll my eyes every time I write/say helper...lol

Undefined variable: fields_form 

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

variable $fields_form does not exist! you've got $this->fields_form instead

[Rhobur]

But  I have tried with $fields_form instead of $this->fields_form and then I still got

Undefined variable: form

[Rhobur]

still :puzzled:
