Basic Usage

To use the CardScheme validator, simply apply it to a property or method on an object that will contain a credit card number.

.. configuration-block::

    .. code-block:: php-annotations

        // src/Entity/Transaction.php
        namespace App\Entity;

        use Symfony\Component\Validator\Constraints as Assert;

        class Transaction
        {
            /**
             * @Assert\CardScheme(
             *     schemes={"VISA"},
             *     message="Your credit card number is invalid."
             * )
             */
            protected $cardNumber;
        }

    .. code-block:: yaml

        # config/validator/validation.yaml
        App\Entity\Transaction:
            properties:
                cardNumber:
                    - CardScheme:
                        schemes: [VISA]
                        message: Your credit card number is invalid.
