我有一个用于“添加”和“编辑”表单的字段集。
字段集实现InputFilterProviderInterface以提供其验证。
在验证添加操作时，我需要检查数据库中不存在具有相同值的数据库记录，因此我使用NoRecordExists验证器。
到目前为止一切都很好。但是，当我在编辑表单中使用相同的字段集时，验证将失败，因为显然已经有一条具有特定值的记录，它是正在编辑的记录。
所以我转向验证器的exclude选项，NoRecordExists并使用我正在编辑的记录的“id”（这是我的主键字段）排除记录。
所以我快到了，唯一我无法解决的是如何获得我想在创建输入过滤器时排除的“id”值getInputFilterSpecification。
这是我的字段集代码。如果有人能告诉我如何从内部访问表单（或绑定对象）的其他属性，getInputFilterSpecification我将非常感激。
也许我需要以不同的方式实现我的 imputfilter 来做到这一点？甚至实现自定义验证器？但是对于看起来非常常规的用例来说，自定义验证器肯定会过大...
提前谢谢了。:wq

编辑：将我的“编辑”控制器操作添加到这篇文章中：
public function editCompetitionAction()
{
$id = $this->params()->fromRoute('competition_id');
$repository = $this->getEntityManager()->getRepository('Kickoff\Model\Entities\Competition');
$competition = $repository->find($id);
if (null == $competition) {
$this->getResponse()->setStatusCode(404);
return;
}
$formManager = $this->serviceLocator->get('FormElementManager');
$form = $formManager->get('Kickoff\Form\Competition\CompetitionForm');
$form->bind($competition);
$request = $this->getRequest();
if ($request->isPost()) {
$form->setData($request->getPost());
$this->logger->debug("Validator is ".print_r($form->getValidator(),1));
if ($form->isValid()) {
$this->getEntityManager()->persist($competition);
$this->getEntityManager()->flush();
}
}
return array(
'form' => $form,
);
}
