ZendFramework2- InputFilter添加InputFilter

Question

我写了一些InputFilters。现在，我使用其中的几个筛选和验证一个表单。因此，我想我可以编写一个新的InputFilter，在构造器中添加我需要的所有其他内容，并将这个新的添加到表单中，但是它需要大量的工作^^，这是我的代码：

样本InputFilter

class MyEmailFilter extends InputFilter
{
    protected $config = array(
        array(
            'name'          => 'email',
            'required'      => true,
            'allow_empty'   => false,
            'validators'    => array(
                array(
                    'name' => 'NotEmpty',
                    'options' => array(
                        'messages' => array(
                            NotEmpty::IS_EMPTY => 'Please type in your emailaddress.',
                        )
                    ),
                    'break_chain_on_failure' => true,
                ),
                array(
                    'name'  => 'EmailAddress',
                    'break_chain_on_failure' => true,
                ),
            ),
        ),
    );

    public function init()
    {
        foreach ($this->config as $name => $input) {
            if (is_string($name)) {
                $this->add($input, $name);
            } else {
                $this->add($input);
            }
        }
    }
 }

我的配置：

return array(
    'input_filters'   => array(
        'invokables' => array(
            'member.myemailfilter' => 'Member\InputFilter\MyEmailFilter',
        ),
        'factories' => array(
            'member.registerfilter' => 'Member\InputFilter\Service\RegisterFilterFactory',
        ),
        'shared'     => array(
            'common.myemailfilter' => true,
            'member.registerfilter' => true,
        ),
    ),
);

我的工厂：

class RegisterFilterFactory implements FactoryInterface
{
    public function createService(ServiceLocatorInterface $inputFilterPluginManager)
    {
        /** @var ServiceLocatorInterface $serviceLocator */
        $serviceLocator = $inputFilterPluginManager->getServiceLocator();

        /** @var MyEmailFilter $emailFilter */
        $emailFilter = $serviceLocator->get('InputFilterManager')->get('member.myemailfilter');

        return new RegisterFilter($emailFilter);
    }
}

RegisterInputFilter (在这里，我添加了表单所需的所有内容)：

class RegisterFilter extends InputFilter
{
    public function __construct(InputFilter $myEmailFilter)
    {
        $this->add($myEmailFilter, 'email');
    }
}

现在，将过滤器添加到我的寄存器控制器中的表单中：

class RegisterController extends AbstractActionController
{
    /**
     * registrierungszeuch
     */
    public function indexAction()
    {
        if ($this->getAuthService()->hasIdentity()) {
            return $this->redirect()->toRoute('home');
        }

        $form = $this->getRegisterForm();

        if ($this->request->isPost()) {
            $form->setData($this->params()->fromPost());
            $form->setInputFilter($this->getRegisterFilter());
            if ($form->isValid()) {
                var_dump('valide');
            } else {
                var_dump('invalide');
            }
        }

        $viewModel = new ViewModel();

        $viewModel
            ->setVariable('form', $form);

        return $viewModel;
    }

    /**
     * @return Form
     */
    private function getRegisterForm()
    {
        return $this->getServiceLocator()->get('FormElementManager')->get('form.user.register');
    }

    /**
     * @return RegisterFilter
     */
    private function getRegisterFilter()
    {
        return $this->getServiceLocator()->get('InputFilterManager')->get('member.registerfilter');
    }
}

当我将myEmailFilter直接添加到表单时，它可以工作，如果我添加了寄存器过滤器，就会得到一个异常。

如何以正确的方式叠加单个过滤器？虽然add()函数也接受InputFilters，但是它看起来很像。

thx求助:-)

你的问题很有说服力。你需要重新考虑你的方法。我有一篇可以考虑的文章和工具，在这里：
