Symfony2数组验证组

Question

由于某些条件，我想使用验证组来验证数组，但是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)

谢谢您帮忙！

您需要使用'allowMissingFields' => true,如下所示：

$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正在检查约束NotBlank验证之前是否存在该字段。
