ZF2 - Multiple entities in a single form - doctrine-orm

Question

I am working on a shopping checkout page which requires:
OrderPerson
PersonAddress (delivery)
Order (notes, time etc. not all items are on the form at present to keep it simple)
I have more or less worked out how to put this together however it requires some tidying up.
My form looks as follows:
To make the forms play nicely together I have setup a CheckoutForm that includes the OrderPerson, PersonAddress and Order Fieldsets:
<?php
namespace MyCart\Form;
use Zend\Form\Element;
use Zend\Form\Fieldset;
use Zend\Form\Form;
use Zend\InputFilter\InputFilterInterface;
class CheckoutForm extends Form
{
public function __construct(
InputFilterInterface $orderFilter,
InputFilterInterface $orderPersonFilter,
InputFilterInterface $personAddressFilter,
$name = null,
$options = array()
) {
parent::__construct('checkout', $options);
$this->orderFilter = $orderFilter;
$this->orderPersonFilter = $orderPersonFilter;
$this->personAddressFilter = $personAddressFilter;
}
public function init()
{
$this->add(
[
'name' => 'csrfcheck',
'type' => 'csrf'
]
);
$this->add(
[
'name' => 'order',
'type' => OrderFieldset::class,
'options' => [
'use_as_base_fieldset' => true
]
]
);
$this->add(
[
'name' => 'order-person',
'type' => OrderPersonFieldset::class,
'options' => [
'use_as_base_fieldset' => true
]
]
);
$this->add(
[
'name' => 'person-address',
'type' => PersonAddressFieldset::class,
'options' => [
'use_as_base_fieldset' => true
]
]
);
$this->add(
[
'name' => 'submit',
'type' => 'submit',
'attributes' => [
'value' => 'Update',
'class' => 'form-element'
]
]
);
$this->getInputFilter()->add($this->orderFilter, 'order');
$this->getInputFilter()->add($this->orderPersonFilter, 'order-person');
$this->getInputFilter()->add($this->personAddressFilter, 'person-address');
}
}
The Checkout Form has a factory:
<?php
namespace MyCart\Form\Factory;
use MyCart\Form\CheckoutForm;
use MyCart\InputFilter\OrderFilter;
use MyCart\InputFilter\OrderPersonFilter;
use MyCart\InputFilter\PersonAddressFilter;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class CheckoutFormFactory implements FactoryInterface
{
/**
* Create service
*
* #param ServiceLocatorInterface $serviceLocator
* #return mixed
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$inputFilter = $serviceLocator->getServiceLocator()->get('InputFilterManager');
return new CheckoutForm(
$inputFilter->get(OrderFilter::class),
$inputFilter->get(OrderPersonFilter::class),
$inputFilter->get(PersonAddressFilter::class)
);
}
}
AS you can see the Checkout Form references the three input filters that are all constructed in the same manner. I have the OrderPerson fieldset here as a reference:
<?php
namespace MyCart\Form;
use Doctrine\Common\Persistence\ObjectManager;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject;
use MyCart\Entity\OrderPerson;
use Zend\Form\Element;
use Zend\Form\Fieldset;
class OrderPersonFieldset extends Fieldset
{
/**
* #var \Doctrine\Common\Persistence\ObjectManager
* #access protected
*/
protected $objectManager;
/**
* #param ObjectManager $objectManager
* #param OrderPerson $orderPrototype
* #param null $name
* #param array $options
*/
public function __construct(
ObjectManager $objectManager,
OrderPerson $orderPrototype,
$name = null,
$options = array()
) {
parent::__construct($name, $options);
$this->objectManager = $objectManager;
$this->setHydrator(new DoctrineObject($objectManager));
$this->setObject($orderPrototype);
}
public function init()
{
$this->add(
[
'name' => 'id',
'type' => 'hidden',
]
);
$this->add(
[
'name' => 'rbu_user_id',
'type' => 'hidden',
]
);
$this->add(
[
'type' => 'text',
'name' => 'email',
'attributes' => [
'class' => 'form-control',
'required' => 'required',
],
'options' => [
'label' => 'Email Address',
'instructions' => 'Please enter your email address',
],
]
);
//etc...
}
}
On execution of the form the CheckoutController is called and this is where I am unsure of what to do or how to save the various objects, this is what I have so far:
public function indexAction()
{
//Pre check stuff here
//Start the form processing
$prg = $this->prg();
if ($prg instanceof Response) {
return $prg;
} elseif ($prg === false) {
//If logged in
if ( $this->authService->hasIdentity()) {
//Update the OrderPerson entity
$user_id = $this->identity()->getId();
$userObject = $this->userService->find($user_id);
$orderPersonEntity = new OrderPerson();
$orderPersonEntity->setRbuUser($userObject);
$orderPersonEntity->setFirstname($userObject->getFirstname());
$orderPersonEntity->setSurname($userObject->getSurname());
$this->checkoutForm->bind($orderPersonEntity);
//Update the person address entity
$personAddress = new PersonAddress();
$personAddress->setAddress1($userObject->getAddress1());
$personAddress->setAddress2($userObject->getAddress2());
$this->checkoutForm->bind($personAddress);
//Update the order entity
}
return new ViewModel(
array(
'cart' => $cart,
'form' => $this->checkoutForm
)
);
}
$this->checkoutForm->setData($prg);
if (!$this->checkoutForm->isValid()) {
return new ViewModel(
array(
'cart' => $cart,
'form' => $this->checkoutForm
)
);
}
$checkoutObject = $this->checkoutForm->getData();
die(var_dump($checkoutObject));
Dumping the result here outputs only the person address object:
object(MyCart\Entity\PersonAddress)[1177]
private 'id' => null
private 'address1' => string 'xx' (length=2)
private 'address2' => string 'xx' (length=2)
private 'region' => null
private 'postCode' => string 'xx' (length=2)
private 'city' => string 'xx' (length=2)
private 'country' => string 'xx' (length=2)
private 'created' => null
private 'modified' => null
private 'orderPerson' => null
So my question is simply, is this the right thinking and how do I complete this so that I can save the three entities in a single go?
