ZF2表单和文档错误

Question

我尝试使用ZF2 Form和Doctirine。但我在C:\Projects\eperde\vendor\zendframework\zendfframework\library\Zend\ServiceManager.php的第行出现了一个错误"致命错误：未捕获的异常'Zend\ServicesManager\exception\InvalidArgumentException'，消息为'$initializer should be callable'"我的Form类路径为true。它是Admin\Form\CategoryForm。

你能帮我吗？怎么了？

public function getFormElementConfig(){
    return array(
        'initializers' => array(
            'invokables' => array(
                'CategoryForm' => 'AdminFormCategoryForm',
            ),
            'ObjectManagerInitializer' => function ($element, $formElements) {
                    if ($element instanceof ObjectManagerAwareInterface) {
                        $services      = $formElements->getServiceLocator();
                        $entityManager = $services->get('DoctrineORMEntityManager');
                        $element->setObjectManager($entityManager);
                    }
                },
        ),
    );
}

我认为这正是您想要做的：

为categoryform创建一个指向AdminFormCategoryForm的别名。添加初始值设定项以注入ObjectManager。我认为工厂会是一种更优雅的方式来做到这一点！

module.config.php（或Module::getConfig()）:

'form_elements' => array(
    'aliases' => array(
        'categoryform' => 'AdminFormCategoryForm',
    ),
    'initializers' => array(
        'ObjectManagerInitializer' => function ($element, $pluginManager) {
            if ($element instanceof DoctrineModulePersistenceObjectManagerAwareInterface) {
                $serviceLocator = $pluginManager->getServiceLocator();
                $entityManager = $serviceLocator->get('DoctrineORMEntityManager');
                $element->setObjectManager($entityManager);
            }
        },
    ),
),
