CardScheme

.. versionadded:: 2.2
    The CardScheme validation is new in Symfony 2.2.

This constraint ensures that a credit card number is valid for a given credit card company. It can be used to validate the number before trying to initiate a payment through a payment gateway.

Applies to :ref:`property or method <validation-property-target>`
Options
Class :class:`Symfony\\Component\\Validator\\Constraints\\CardScheme`
Validator :class:`Symfony\\Component\\Validator\\Constraints\\CardSchemeValidator`

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:: yaml

        # src/Acme/SubscriptionBundle/Resources/config/validation.yml
        Acme\SubscriptionBundle\Entity\Transaction:
            properties:
                cardNumber:
                    - CardScheme:
                        schemes: [VISA]
                        message: Your credit card number is invalid.

    .. code-block:: xml

                        </option>
                        <option name="message">Your credit card number is invalid.</option>
                    </constraint>
                </property>
            </class>

             */
            protected $cardNumber;
        }

    .. code-block:: php

        // src/Acme/SubscriptionBundle/Entity/Transaction.php
        namespace Acme\SubscriptionBundle\Entity\Transaction;

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

        class Transaction
