Question

我尝试创建我的验证器，但是它不起作用。文档无济于事，因为它只关心对象验证，并提供了一个数组验证示例。

我正在尝试根据随数据一起发送的字段来验证我的数据。因此，请求中包含type，credentials或google的字段facebook，并根据此字段的值来验证其他字段。当然，type必须先通过验证。

我尝试遵循集合文档，但只得到了意外的异常和结果。有时会出错，有时会出错，但事情并没有按预期工作。

给出以下示例：

use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Validation;

require_once(__DIR__ . "/../vendor/autoload.php");

$validator = Validation::createValidator();

$constraints = new Assert\Collection([
    "type" => [
        new Assert\Required([
            "groups" => ["type"],
            "constraints" => new Assert\Choice([
                "choices" => ["credentials", "facebook", "google"],
            ])
        ]),
    ],
    "username" => [
        new Assert\NotBlank([
            "groups" => ["credentials", "facebook", "google"]
        ])
    ],
    "password" => [
        new Assert\NotBlank([
            "groups" => ["credentials"]
        ]),
        new Assert\Length([
            "min" => 6,
            "groups" => ["credentials"]
        ]),
    ],
    "passwordConfirm" => [
        new Assert\NotBlank([
            "groups" => ["credentials"],
        ]),
        new Assert\IdenticalTo([
            "groups" => ["credentials"],
            "propertyPath" => "password"
        ])
    ]
]);

$data = [];

$errors = $validator->validate($data, $constraints, "credentials");


foreach ($errors as $error) {
    echo $error->getPropertyPath() . ": " . $error->getMessage() . "<br />";
}

将输出：

[type]: This field is missing.
[username]: This field is missing.
[password]: This field is missing.
[passwordConfirm]: This field is missing.

即使我已将"credentials"明确传递给组。 Ive也尝试使用fields选项，但是它引入了更多问题。有谁知道如何正确使用验证器并使用组实际上仅验证数据的子集。

您为什么使用Assert\Collection？这对于验证一组相似的对象/物品很有用

我认为您应该将$constraints = new Assert\Collection([替换为$constraints = [，以表示您应该使用简单的约束数组

Symfony约束验证不起作用，组被忽略
