只有当来自CollectionType的输入存在于窗体上时，我如何验证AdMenuLinkType形式的CollectionType。Symfony2 CollectionType验证
例如：当我在浏览器中打开添加表单时，我可以创建没有路由参数的链接。当我点击按钮“添加参数” - JavaScript从AdMenuRouteDataType窗体呈现2个字段。这两个字段必须是必需的而不是空的。如果我使用这些空白字段提交表单 - 我需要获取错误。如果我不点击“添加参数”按钮，集合输入字段不呈现，我可以提交表单没有这些数据和错误。我如何做到这一点？
我有实体：AdMenuRouteData
<?php
namespace AdBackendBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* AdMenuRouteData
*
* @ORM\Table(name="ad_menu_route_data")
* @ORM\Entity(repositoryClass="AdBackendBundle\Repository\AdMenuRouteDataRepository")
*/
class AdMenuRouteData
{
/**
* @var int
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\ManyToOne(targetEntity="AdBackendBundle\Entity\AdMenuLink", inversedBy="routeData")
* @ORM\JoinColumn(name="link_id", referencedColumnName="id", onDelete="CASCADE")
*/
private $link;
/**
* @var string
*
* @ORM\Column(name="parameter", type="string", length=255)
* @Assert\NotBlank(message="ad_menu_route_data.parameter.blank")
*/
private $parameter;
/**
* @var string
*
* @ORM\Column(name="value", type="string", length=255)
* @Assert\NotBlank(message="ad_menu_route_data.value.blank")
*/
private $value;
/**
* Get id
*
* @return int
*/
public function getId()
{
return $this->id;
}
/**
* @return mixed
*/
public function getLink()
{
return $this->link;
}
/**
* @param mixed $link
*/
public function setLink($link)
{
$this->link = $link;
}
/**
* Set parameter
*
* @param string $parameter
*
* @return AdMenuRouteData
*/
public function setParameter($parameter)
{
$this->parameter = $parameter;
return $this;
}
/**

*
* @return string
*/
public function getParameter()
{
return $this->parameter;
}
/**

*

*

*/
public function setValue($value)
{
$this->value = $value;
return $this;

如果您在JavaScript中验证它并在发送表单之前删除空字段，该怎么办？ – Pipe
不，我想通过Symfony2约束条件验证 – trauma
请将此代码缩减为必要的最小数量。 – Teepeemm
