ZF2 - 通过工厂自定义验证器

Question

我无法通过工厂加载我的 CustomValidator：

namespace My\Validator;
class CustomValidator extends AbstractValidator
{
public function __construct(EntityManager $em, AuthenticationService $auth)
{
    $this->auth = $auth;
    $this->em = $em;

    parent::__construct();
}

模块（我的）配置:

namespace My;
...
'service_manager' => array(
  'abstract_factories' => array(
    'Application\Factory\FormAbstractFactory'
  ),
),
'controllers' => array(
    'factories' => array(
        'My\Controller\CustomController' => 'My\Factory\Controller\CustomControllerFactory',
    ),
),
'validators' => array(
    'factories' => array(
        'My\Validator\CustomValidator' => 'My\Factory\Validator\CustomValidatorFactory'
    ),
),

自定义表单:

namespace My\Form;
class CustomForm extends SearchForm implements InputFilterProviderInterface {
    public function __construct(ObjectManager $objectManager, Translator $translator) {
        parent::__construct ($objectManager, $translator,  "customForm" );
        // Here are some elements added...
        $this->add(array("name" => "search", /* some more properties */));
    }

    public function getInputFilterSpecification()
    {
        return array(
            'search' => array(
                'validators' => array(
                    array(
                        'name' => 'My\Validator\CustomValidator'
                    )
                )
            )
        );
    }
}

CustomValidatorFactory:

namespace My\Factory\Validator;
class CustomValidatorFactory implements FactoryInterface {
public function createService(ServiceLocatorInterface $serviceLocator)
{
    $sl = $serviceLocator->get("service_manager");
    $entityManager = $sl->get('doctrine.entitymanager.orm_default');
    $auth = $sl->get('zfcuser_auth_service');

    return new CustomValidator($entityManager, $auth);
}

我收到一个 PHP 错误，指出 __construct 的第一个参数 ($em) 必须是 EntityManager 的一个实例，none 给出... 我的工厂没有实例化......我认为我的 CustomValidator 仍然是由其他工厂（或 ValidatorPluginManager？）创建的...... 我必须如何更改我的代码才能让我的 CustomValidatorFactory 正常工作？

编辑 - 通过使用附有我的自定义验证器的表单呈现视图来完成异常：

EDIT2 - FormAbstractFactory:

class FormAbstractFactory implements AbstractFactoryInterface {

    public function canCreateServiceWithName(ServiceLocatorInterface $serviceLocator, $name, $requestedName)
    {
        return (fnmatch('*Form', $requestedName)) ? true : false;
    }

    public function createServiceWithName(ServiceLocatorInterface $serviceLocator, $name, $requestedName)
    {
        if (class_exists($requestedName)) {
            $entityManager = $serviceLocator->get('doctrine.entitymanager.orm_default');
            $translator    = $serviceLocator->get('translator');

            return new $requestedName($entityManager, $translator);
        }

        return false;
    }

}

CustomControllerFactory:

namespace My\Factory\Controller;
use My\Controller\CustomController;
class CustomControllerFactory implements FactoryInterface
{
    public function createService(ServiceLocatorInterface $serviceLocator)
    {
        $realServiceLocator = $serviceLocator->getServiceLocator();
        $entityManager      = $realServiceLocator->get('doctrine.entitymanager.orm_default');
        // Created through FormAbstractFactory
        $customForm          = $realServiceLocator->get('My\Form\CustomForm');
        $orderByService     = $realServiceLocator->get('Application\Service\OrderByServiceAbstract');

        return new CustomController($entityManager, $customForm, $orderByService);
    }
}

自定义控制器

namespace My\Controller;

class CustomController extends AbstractActionController
{
    public function __construct(ObjectManager $entityManager, CustomForm $customForm, OrderByService $orderByService)
    {
        $this->em = $entityManager;
        $this->form = $customForm;
        $this->orderByService = $orderByService;
    }

    public function indexAction()
    {
        // some code...

        $vm = new ViewModel (array(
            "form" => $this->form
        ));

        $vm->setTemplate("my/custom/index");

        return $vm;
    }
}

my/custom/index - 查看：

<?php
namespace My;
$form = $this->form;
$form->prepare(); ?>
<!-- HTML Stuff... ->
<?php echo $this->form($form, null); ?>
<!-- HTML Stuff... ->

好吧，我也在使用自定义表单渲染器 - https://github.com/neilime/zf2-twb-bundle。

我在 zf2 的 git 提交了一个问题：https://github.com/zendframework/zf2/issues/7688

Answer 1

您正在通过 ServiceManager 创建表单。

$customForm = $realServiceLocator->get('My\Form\CustomForm');

这意味着您将抽象工厂注册到 服务管理器 而不是表单元素管理器。通过这样做，将创建表单 without form factory's input filter being correctly prepared.

将此配置移动到 'form_elements' 键。

'form_elements' => [
     'abstract_factories' => [
          'My\Form\FormAbstractFactory',
     ],
 ]

在 CustomControllerFactory 中，您需要更新到。

$formElementManager = $realServiceLocator->get('FormElementManager');
$customForm = $formElementManager->get('My\Form\CustomForm');

最后 FormAbstractFactory::createServiceWithName() 方法现在需要 $serviceLocator = $serviceLocator->getServiceLocator() 在顶部。
