PHP

// src/AppBundle/Entity/User.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Mapping\ClassMetadata;
use Symfony\Component\Validator\Constraints as Assert;

class User
{
    public static function loadValidationMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('country', new Assert\Country());
    }
}

Options¶

message¶

type: string default: This value is not a valid country.

This message is shown if the string is not a valid country code.

payload¶

type: mixed default: null

This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.

For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
