Important!

This bundle is partially maintained. No new features will be added but some PR will be merged for compatibility or security.

LexikPayboxBundle makes the use of Paybox payment system easier by doing all the boring things for you.

LexikPayboxBundle silently does :

  • hmac hash calculation of parameters during request.
  • server testing before request to be sure it is up.
  • signature verification with openssl on ipn response.
  • triggers an event on response.

You only need to provide parameters of your transaction, customize the response page and wait for the event triggered on ipn response.

Requirements

  • PECL hash >= 1.1
  • openssl enabled

Installation

Installation with composer :

composer require lexik/paybox-bundle

Add this bundle to your app/AppKernel.php :

public function registerBundles()
{
    return array(
        // ...
        new Lexik\Bundle\PayboxBundle\LexikPayboxBundle(),
        // ...
    );
}

                hmac:
                    algorithm:      sha512 # signature algorithm
                    signature_name: Sign   # customize the signature parameter name

The routing collection must be set in your routing.yml

# Lexik Paybox Bundle
lexik_paybox:
    resource: '@LexikPayboxBundle/Resources/config/routing.yml'

Usage of Paybox System

The bundle includes a sample controller SampleController.php with two actions.

...
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

/**
 * Sample action to call a payment.
 * It create the form to submit with all parameters.
 */
public function indexAction($account)
{
    $service = sprintf('lexik_paybox.request_handler.%s', $account);

    if (!$this->has($service)) {
        throw new NotFoundHttpException(sprintf('Service %s not found', $service));
    }

    $paybox = $this->get($service);
    $paybox->setParameters(array(
        'PBX_CMD'          => 'CMD'.time(),
        'PBX_DEVISE'       => '978',
        'PBX_PORTEUR'      => 'test@paybox.com',
        'PBX_RETOUR'       => 'Mt:M;Ref:R;Auto:A;Erreur:E',
        'PBX_TOTAL'        => '1000',
        'PBX_TYPEPAIEMENT' => 'CARTE',
        'PBX_TYPECARTE'    => 'CB',
        'PBX_EFFECTUE'     => $this->generateUrl('lexik_paybox_sample_return', array('account' => $account, 'status' => 'success'), UrlGenerator::ABSOLUTE_URL),
        'PBX_REFUSE'       => $this->generateUrl('lexik_paybox_sample_return', array('account' => $account, 'status' => 'denied'), UrlGenerator::ABSOLUTE_URL),
        'PBX_ANNULE'       => $this->generateUrl('lexik_paybox_sample_return', array('account' => $account, 'status' => 'canceled'), UrlGenerator::ABSOLUTE_URL),
        'PBX_RUF1'         => 'POST',
        'PBX_REPONDRE_A'   => $this->generateUrl('lexik_paybox_ipn', array('account' => $account, 'time' => time()), UrlGenerator::ABSOLUTE_URL),
    ));

    return $this->render(
        'LexikPayboxBundle:Sample:index.html.twig',
        array(
            'url'  => $paybox->getUrl(),
            'form' => $paybox->getForm()->createView(),
        )
    );
}
...
/**
 * Sample action of a confirmation payment page on witch the user is sent
 * after he seizes his payment informations on the Paybox's platform.
 * This action must only containts presentation logic.
 */
public function returnAction(Request $request, $status, $account)
{
    return $this->render('LexikPayboxBundle:Sample:return.html.twig', array(
        'status'     => $status,
        'account'    => $account,
        'parameters' => $request->query,
    ));
}
...

The getUrl() method silently does a server check and throws an exception if the destination server does not respond.

The payment confirmation in your business logic must be done when the instant payment notification (IPN) occurs. The plugin contains a controller with an action that manages this IPN and triggers an event. The event contains all data transmetted during the request and a boolean that tells if signature verification was successful.

The bundle contains a listener example that simply create a file on each ipn call.

namespace Lexik\Bundle\PayboxBundle\Listener;

use Lexik\Bundle\PayboxBundle\Event\PayboxResponseEvent;
use Symfony\Component\Filesystem\Filesystem;

/**
 * Sample listener that create a file for each ipn call.
 */
class SampleIpnListener
{
    /**
     * @var string
     */
    private $rootDir;

    /**
     * @var Filesystem
     */
    private $filesystem;

    /**
     * Constructor.
     *
     * @param string     $rootDir
     * @param Filesystem $filesystem
     */
    public function __construct($rootDir, Filesystem $filesystem)
    {
        $this->rootDir = $rootDir;
        $this->filesystem = $filesystem;
    }

    /**
     * Creates a txt file containing all parameters for each IPN.
     *
     * @param PayboxResponseEvent $event
     */
    public function onPayboxIpnResponse(PayboxResponseEvent $event)
    {
        $path = sprintf('%s/../data/%s', $this->rootDir, date('Y\/m\/d\/'));
        $this->filesystem->mkdir($path);

        $content = sprintf('Account : %s%s', $event->getAccount(), PHP_EOL);
        $content .= sprintf('Signature verification : %s%s', $event->isVerified() ? 'OK' : 'KO', PHP_EOL);
        foreach ($event->getData() as $key => $value) {
            $content .= sprintf("%s:%s%s", $key, $value, PHP_EOL);
        }

        file_put_contents(
            sprintf('%s%s.txt', $path, time()),
            $content
        );
    }
}

To create your own listener, you just have to make it wait for the "paybox.ipn_response" event. For example the listener of the bundle:

parameters:
    lexik_paybox.sample_response_listener.class: 'Lexik\Bundle\PayboxBundle\Listener\SampleIpnListener'

services:
    ...
    lexik_paybox.sample_response_listener:
        class: '%lexik_paybox.sample_response_listener.class%'
        arguments: [ '%kernel.root_dir%', '@filesystem' ]
        tags:
            - { name: kernel.event_listener, event: paybox.ipn_response, method: onPayboxIpnResponse }
