ZF2 add elemets to form on the fly from database - php

Question

In ZF2, I get the form from the controller factory like this:
class SomeControllerFactory implements FactoryInterface
{
public function CreateService(SeviceLocatorInterface $serviceLocator)
{
$realServiceLocator = $serviceLocator->getServiceLocator();
// other things from service manager
$registrationForm = $realServiceLocator->get('FormElementManager')
->get('Path\To\My\Form\RegistrationForm');
}
return new SomeController(
// controller dependencies, including $registrationForm
);
}
In the RegistrationForm, I have MultiCheckBox:
$this->add([
'type' => 'Zend\Form\Element\MultiCheckBox',
'name' => 'partyRoleIds',
'options' => [
'label' => 'Отношение',
'value_options' => [
[
'value' => '1',
'label' => 'client',
],
[
'value' => '2',
'label' => 'prospect'],
[
'value' => '6',
'label' => 'contractor',
],
],
],
]);
I want to populate value_options from a db query that returns an array like [1 => 'client', 2 => 'prospect'...]. Populating is not an problem, but I don't know how to pass this array as a dependency into the RegistrationForm because in the call $registrationForm = $realServiceLocator->get('FormElementManager')->get('Path\To\My\Form\RegistrationForm');, I don't have any place to add the dependency.
How could I do this?
PS: rewritten the question, please forgive my initial brevity.

Answer 1

In form classes you add the method :
public function setValueOptions($element, array $values_options)
{
$e = $this->get($element);
$e->setValueOptions($values_options);
return $this;
}
In your controller, if your form is $registrationForm you write :
$registrationForm->setValueOptions('partyRoleIds', $valueOptions);
where $valueOptions is an array like your sample.
