我目前正在从事一个涉及 Zend Framework 2 和 Doctrine 的项目。
我正在实现 Zend\Form 并使用 DoctrineORMModule\Stdlib\Hydrator\DoctrineEntity 从/向数据库提取和水合数据。
在我读过的大部分教程中，当您需要在水合对象之前转换特定值（在我的示例中是日期时间值字符串，当使用教义）。然而，尽管我尽最大努力实现这一点，但似乎只调用了我的水合策略中的 extract() 方法，而不是 hydrate() 方法。曾经！
为了提供一个代码示例，这就是我正在做的 - 为了简洁起见，我缩短了代码的某些方面；
// 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;
}
}
