Basic Usage

To verify that the "age" field of a class is "18" or greater, you might add the following:

.. configuration-block::

    .. code-block:: yaml

        # src/Acme/EventBundle/Resources/config/validation.yml
        Acme\EventBundle\Entity\Participant:
            properties:
                age:
                    - Min: { limit: 18, message: You must be 18 or older to enter. }

    .. code-block:: php-annotations

        // src/Acme/EventBundle/Entity/Participant.php
        use Symfony\Component\Validator\Constraints as Assert;

        class Participant
        {
            /**
             * @Assert\Min(limit = "18", message = "You must be 18 or older to enter")
             */
             protected $age;
        }

The message that will be shown if the underlying value is less than the limit option.

invalidMessage

type: string default: This value should be a valid number

The message that will be shown if the underlying value is not a number (per the is_numeric PHP function).
