我在 ZF2 应用程序中有以下类和我的模块配置，它给出了以下错误：
While attempting to create applicationformuserform(alias: Application\Form
\UserForm) an invalid factory was registered for this instance type.
用户窗体工厂.php
<?php
namespace Application\Factory\Form;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Application\Form\UserForm;
class UserFormFactory implements FactoryInterface {
public function createService(ServiceLocatorInterface $serviceLocator) {
$services = $serviceLocator->getServiceLocator();
$entityManager = $services->get('Doctrine\ORM\EntityManager');
$form = new UserForm($entityManager);
return $form;
}
}
?>
用户窗体.php
<?php
namespace Application\Form;
use Zend\Form\Form;
use Zend\InputFilter\InputFilterProviderInterface;
use Doctrine\ORM\EntityManager;
class UserForm extends Form implements InputFilterProviderInterface {
protected $entityManager;
public function __construct(EntityManager $entityManager) {
parent::__construct();
$this->entityManager = $entityManager;
}
public function init() {
$this->add(array(
'name' => 'username',
'attributes' => array(
'type' => 'text',
),
'options' => array(
'label' => 'User Name',
),
));
$this->add(array(
'name' => 'first_name',
'attributes' => array(
'type' => 'text',
),
'options' => array(
'label' => 'First Name',
),
));
$this->add(array(
'name' => 'last_name',
'attributes' => array(
'type' => 'text',
),
'options' => array(
'label' => 'Last Name',
),
));
$this->add(array(
'name' => 'role_id',
'type' => 'DoctrineModule\Form\Element\ObjectSelect',
'options' => array(
'object_manager' => $this->entityManager,
'target_class' => 'Application\Entity\Role',
'property' => 'id',
'is_method' => true,
'find_method' => array(
'name' => 'getRoles',
),
'label' => 'User Role',
),
));
}
public function getInputFilterSpecification() {
return array(); // filter and validation here
}
}
?>
模块.config.php
'form_elements' => array(
'factories' => array(
'Application\Form\UserForm' => 'Application\Factory\Form\UserFormFactory',
),
),
我在另一个控制器工厂中使用这个表单工厂
用户控制器工厂.php
<?php
namespace Member\Factory\Controller;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Member\Controller\UserController;
use Application\Form\UserForm;
class UserControllerFactory implements FactoryInterface {
public function createService(ServiceLocatorInterface $serviceLocator) {
$services = $serviceLocator->getServiceLocator();
$userForm = $services->get('FormElementManager')->get('Application\Form\UserForm');
$controller = new UserController($userForm);
return $controller;
}
}
?>
谁能告诉我可能是什么问题？
