I am currently working on a project involving Zend Framework 2 and Doctrine.
I am implementing a Zend\Form and using the DoctrineORMModule\Stdlib\Hydrator\DoctrineEntity to extract and hydrate data from/to the database.
In much of the tutorials I have read, it is ideal to implement the Zend\Stdlib\Hydrator\Strategy\StrategyInterface when you need to convert a specific value before hydrating an object (in my example a date time value string which is an issue when using Doctrine). However, despite my best efforts to implement this, it seems only that the extract() method in my hydration strategy is called, never the hydrate() method. EVER!
To provide a code example, this is what I am doing - I have shortened some aspects of the code for brevity;
// Service
public function getProposerForm() {
// get required classes from service manager
$proposerEntity = $this->getServiceManager()->get('tourers_entity_proposer');
$entityManager = $this->getServiceManager()->get('Doctrine\ORM\EntityManager');
$formManager = $this->getServiceManager()->get('FormElementManager');
$proposerFieldset = $formManager->get('tourers_form_proposer_fieldset');
$proposerForm = $formManager->get('tourers_form_proposal');
$proposerFieldset->setUseAsBaseFieldset(true);
$proposerForm->add($proposerFieldset);
$proposerForm->get('submit')->setValue('Continue');
$proposerForm->bind($proposerEntity);
return $proposerForm;
}
.
// Controller
public function proposerAction() {
// grab the form from the form service
$formService = $this->getServiceLocator()->get('tourers_service_forms');
$form = $formService->getProposerForm();
if (true === $this->getRequest()->isPost()) {
$form->setData($this->getRequest()->getPost());
if (true === $form->isValid()) {
$proposerEntity = $form->getData();
$encryptedPolicyId = $formService->saveProposerForm($proposerEntity, $policyId);
return $this->redirect()->toRoute('tourers/proposal/caravan',array('policyid' => $encryptedPolicyId));
} else {
$errors = $form->getMessages();
var_dump($errors);
}
}
// view
return new ViewModel(array(
'form' => $form
,'policyid' => $policyId
)
);
}
.
// Form
class ProposerFieldset extends Fieldset implements InputFilterProviderInterface, ObjectManagerAwareInterface
{
/**
* @var Doctrine\ORM\EntityManager
*/
private $objectManager;
/**
* @return Zend\Form\Fieldset
*/
public function init()
{
// set name
parent::__construct('Proposer');
// set the hydrator to the domain object
$hydrator = new DoctrineEntity($this->objectManager,true);
$hydrator->addStrategy('proposerDateOfBirth',new DateStrategy);
$this->setHydrator($hydrator);
// other form elements below here including proposerDateOfBirth
$minDate = date('dd\/mm\/yyyy',strtotime('-100 years'));
$maxDate = date('dd\/mm\/yyyy',strtotime('-16 years'));
$this->add(array(
'name' => 'proposerDateOfBirth'
,'type' => 'Zend\Form\Element\Date'
,'attributes' => array(
'class' => 'form-control'
,'id' => 'proposerDateOfBirth'
,'placeholder' => 'dd/mm/yyyy'
,'min' => $minDate
,'max' => $maxDate
,'data-date-format' => 'dd/mm/yyyy'
),
'options' => array(
'label' => 'Date of Birth',
)
));
}
}
.
// Hydrator Strategy
namespace Tourers\Hydrator\Strategy;
use Zend\Stdlib\Hydrator\Strategy\StrategyInterface;
class DateStrategy implements StrategyInterface {
/**
* (non-PHPdoc)
* @see Zend\Stdlib\Hydrator\Strategy.StrategyInterface::extract()
*/
public function extract($value) {
var_dump($value . ' extracted'); // GETS CALLED
return $value;
}
/**
* (non-PHPdoc)
* @see Zend\Stdlib\Hydrator\Strategy.StrategyInterface::hydrate()
*/
public function hydrate($value) {
var_dump($value . ' hydrated'); // NEVER CALLED
return $value;
}
}
