使用多维集合进行Symfony验证

Question

我正在尝试使用symfony验证器进行样本验证，我的数据数组如下所示：

$data = array("firstname" => "", "lastname" => "", "address" => array("street" => "", "city" => ""));

我的约束数组就像

 $valueConstraints = array("firstname" => new NotBlank(array('message' => "Please fill firstname")),
            "lastname" => new NotBlank(array('message' => "Please fill lastname")),
            "address" => array("street" => new NotBlank(array('message' => "Please fill the street for address field")),
                "city" => new NotBlank(array('message' => "Please fill city for  address field"))));

但是当我试图建立一个集合时

$collectionConstraint = new Collection($constraints)

抛出约束错误：

The options \"street\", \"city\" do not exist in constraint

街道和城市选项属于地址类别，不知道是否可以使用symfony验证程序以多维数组格式创建约束。 / p>
