Injecting variables into Forms __construct function Zend 2 - forms

Question

I am trying to prepopulate a form's drop down options via data stored statically in the module.config.php in Zend 2 and am running into a problem which entails:
I try to get the Servicemanager in the __construct() function but it is unavailable.
I move the element declarations to another function within the form class so I can pass variables into it but the view controller cannot find the elements.
I currently call the form via a Servicemanager Invokable. How can I pass these arrays into the form's __construct() function?
Here is the code:
class ILLForm extends Form
{
public function __construct($fieldsetName, $campuses, $ILLTypes, $getFromOptions)
{
parent::__construct('create_ill');
$this
->setAttribute('method', 'post')
->setHydrator(new ClassMethodsHydrator(false))
->setInputFilter(new InputFilter())
;
$ill = new ILLFieldset('ill', $campuses, $ILLTypes, $getFromOptions);
$ill->setName('ill')
->setOptions(array(
'use_as_base_fieldset' => true,
));
$captcha = new Element\Captcha('captcha');
$captchaAdapter = new Captcha\Dumb();
$captchaAdapter->setWordlen(5);
$captcha->setCaptcha($captchaAdapter)
->setLabelAttributes(array('class' => 'sq-form-question-title'))
->setAttribute('class', 'sq-form-field required')
->setLabel("* Captcha")
->setAttribute('title', 'Help to prevent SPAM');
$submit = new Element\Submit('submit');
$submit->setAttribute('value', 'Submit ILL')
->setAttribute('class', 'sq-form-submit')
->setAttribute('title', 'Submit ILL');
$this->add($ill)
->add($captcha)
->add($submit);
}
}
The Indexcontroller Factory that calls the Form:
class IndexControllerFactory implements FactoryInterface
{
public function createService(ServiceLocatorInterface $controllers)
{
$allServices = $controllers->getServiceLocator();
$sm = $allServices->get('ServiceManager');
$smConfig = $allServices->get('config');
$campuses = $smConfig['campuses'];
$illCategories = $smConfig['ILLCategories'];
$getFromOptions = $smConfig['getFromOptions'];
$controller = new IndexController();
$controller->setCampuses($campuses);
$controller->setILLCategories($illCategories);
$controller->setGetFromOptions($getFromOptions);
$controller->setILLForm($sm->get('ILL-form'));
$controller->setILLFormFilter($sm->get('ILL-form-filter'));
//$controller->setParams($sm->get('params'));
return $controller;
}
}
and the relevant module.config.php excerpt:
'service_manager' => array(
'abstract_factories' => array(
'Zend\Cache\Service\StorageCacheAbstractServiceFactory',
'Zend\Log\LoggerAbstractServiceFactory',
),
'invokables' => array(
'ILL-form-filter' => 'ILL\Form\ILLFormFilter',
'ILL-form' => 'ILL\Form\ILLForm',
),

Answer 1

I ended up taking the form out of the service manager invokables in module.config.php (removed line for 'ILL-form') and call it from the indexControllerFactory.php instead
$create_ill = new Form\ILLForm('create_ill', $campuses, $illCategories, $getFromOptions);
$controller->setILLForm($create_ill);
instead of
$controller->setILLForm($sm->get('ILL-form'));
