Question

我的控制器中有以下代码。

$em = $this->getDoctrine()->getEntityManager();
    $entity = $em->getRepository('CIInventoryBundle:DiscountLevelItem')->find($discountLevelItemId);
    $form = $this->createForm(new DiscountLevelItemCollectionType(), $entity);
    $form->bindRequest($request);

    $errors = array();
    foreach ($form['discountLevelItemProducts'] as $formField) {
        $errors[] = $formField->getErrors();
    }
    var_dump($errors);
    die;

    if ($form->isValid()) {
        //remove items without discount type
        foreach ($entity->getDiscountLevelItemProducts() as $item) {
            if (!$item->getDiscountType()) {
                $entity->getDiscountLevelItemProducts()->removeElement($item);
                $em->remove($item);
            }
        }

        $em->persist($entity);
        $em->flush();

        $responseData = array(
            'status' => 'success',
            'message' => 'Supplier product discounts successfully saved.'
        );
    } else {
        $responseData = array(
            'status' => 'error',
            'form' => $this-        >renderView('CIInventoryBundle:DiscountLevel:manageProducts.html.twig', array(
                'entity' => $entity,
                'form' => $form->createView()
            ))
        );
    }
    return new Response(json_encode($responseData), 200, array('Content-Type'=>'application/json'));

我提交了以下数据：

ci_inventorybundle_discountlevelitemcollectiontype [_token]：17044e40450d5546f4be40e6fbe28f2866dffcfb ci_inventorybundle_discountlevelitemcollectiontype [discountLevelItemProducts] [2] [货运]：0.00 ci_inventorybundle_discountlevelitemcollectiontype [discountLevelItemProducts] [2] [discountValue]：0.00 ci_inventorybundle_discountlevelitemcollectiontype [discountLevelItemProducts] [2] [discountType]：固定 ci_inventorybundle_discountlevelitemcollectiontype [discountLevelItemProducts] [2] [变型]：1567

当我尝试var_dump $ errors我得到以下数据：

 array(2) {
  [0]=>
  array(0) {
  }
  [1]=>
  array(0) {
  }
}

我使用的是Symfony 2.0.23。

我的问题是如何以编程方式获取表单集合的表单错误？

谢谢！

您可以将getErrorsAsString方法作为示例来获取所需的功能。您还必须在表单字段中设置invalid_message选项以更改This value is invalid消息。
