Question

仅当表格中存在来自CollectionType的输入时，我才能以AdMenuLinkType形式验证CollectionType。

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“添加参数”按钮时 - javascript渲染AdMenuRouteDataType表单中的2个字段。这两个字段必须是必填字段而不是空字段。如果我使用这些空字段提交表单 - 我需要收到错误。如果我没有点击“添加参数”按钮，集合输入字段不会呈现，我可以提交没有此数据和错误的表单。我怎么能这样做？

我有实体：AdMenuRouteData

<?php

    {
        return $this->link;
    }

    /**

    public function setLink($link)
    {
        $this->link = $link;

我使用AdMenuLink的表单类型：

Answer 1

我使用assert Valid（）来执行此任务，并且可以正常工作。

/**
     * @ORM\OneToMany(targetEntity="AdBackendBundle\Entity\AdMenuRouteData", mappedBy="link", cascade={"persist"})
     * @Assert\Valid()
     */
    private $routeData;
