New in Symfony 2.2: Payment related validators
December 12, 2012
Fabien Potencier
If you are developing an e-commerce solution based on Symfony2, you might want to validate a credit card number before sending it to your payment gateway. Doing so is very simple in Symfony 2.2 thanks to the Luhn algorithm and its implementation as a validator:
1 2 3 4 5 6 7 8 9 10 11 | // src/Acme/SubscriptionBundle/Entity/Transaction.php
use Symfony\Component\Validator\Constraints as Assert;
class Transaction
{
/**
* @Assert\Luhn(message = "Please check your credit card number.")
*/
protected $cardNumber;
}
|
You can also check the card scheme thanks to
Symfony\Component\Validator\Constraints\CardSchemeValidator.

Wow! It's awesome!
Great job! Financial validators was most buggy place when somebody wrote it in project!
Cool. I was using https://github.com/umpirsky/zymfony-validator for this.
BTW, it would be nice to notify translators to provide translation for this new message in as many languages as possible.
Nice!
It's not a Luhn validator, This validator is a number check, php implementation of Luhn algorithm can be found here http://rosettacode.org/wiki/Luhn_test_of_credit_card_numbers#PHP
good job
@Francis it is the real luhn algorithm, check : https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Validator/Constraints/LuhnValidator.php#L49
Wow, I'm loving these 'New in SF2' articles - nice way to communicate the changes without me looking for new features in change logs etc.
User may need multi language here.
@Pascal that'll teach me to read the articles too fast, thank you for providing the link
Thumbs up!
