Basic Usage¶

If you want to ensure that the age of a Person class is less than or equal to 80, you could do the following:

Annotations

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

use Symfony\Component\Validator\Constraints as Assert;

class Person
{
    /**
     * @Assert\LessThanOrEqual(
     *     value = 80
     * )
     */
    protected $age;
}

YAML

# src/AppBundle/Resources/config/validation.yml
AppBundle\Entity\Person:
    properties:
        age:
            - LessThanOrEqual:
                value: 80

class Person
{
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('age', new Assert\LessThanOrEqual(array(
            'value' => 80,
        )));
    }
}
