Php 阵列的Symfony2验证组

由于某些条件，我想使用验证组验证数组，但验证组似乎不会影响数组

$params = [
    'type' => 'a',
    'province' => 'b',
    'district' => 'c'
];

$constraints = new Collection([
    'type' => [new NotBlank()],

    'province' => [new NotBlank(['groups' => ['selection']])],
    'district' => [new NotBlank(['groups' => ['selection']])],

    'distance' => [new NotBlank(['groups' => ['location']])],
    'lat' => [new NotBlank(['groups' => ['location']])],
    'lon' => [new NotBlank(['groups' => ['location']])],
]);

$errors = $this->container->get('validator')->validate($params, $constraints, ['selection']);

验证错误：

Array[distance]:
This field is missing. (code 1)
Array[lat]:
This field is missing. (code 1)
Array[lon]:
This field is missing. (code 1)

谢谢你的帮助

您需要像这样使用

'allowMissingFields'=>true，

：

$constraints = new Collection(
'allowMissingFields' => true,
'fields' => [
    'type' => [new NotBlank()],

    'province' => [new NotBlank(['groups' => ['selection']])],
    'district' => [new NotBlank(['groups' => ['selection']])],

    'distance' => [new NotBlank(['groups' => ['location']])],
    'lat' => [new NotBlank(['groups' => ['location']])],
    'lon' => [new NotBlank(['groups' => ['location']])],
]);

CollectionValidator正在验证约束NotBlank之前检查字段是否存在
