CardScheme

New in version 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 property or method
Options
Class Symfony\Component\Validator\Constraints\CardScheme
Validator 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.
