// src/Acme/JournalBundle/Entity/Journal.php
namespace Acme\JournalBundle\Entity;

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

class Journal
{
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('issn', new Assert\Issn());
    }
}

Options¶

message¶

type: String default: This value is not a valid ISSN.

The message shown if the given value is not a valid ISSN.

caseSensitive¶

type: boolean default: false

The validator will allow ISSN values to end with a lower case ‘x’ by default. When switching this to true, the validator requires an upper case ‘X’.

requireHyphen¶

type: boolean default: false

The validator will allow non hyphenated ISSN values by default. When switching this to true, the validator requires a hyphenated ISSN value.

payload¶

type: mixed default: null

New in version 2.6: The payload option was introduced in Symfony 2.6.

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.
