Get Started

In this chapter we are going to setup payum package and do simple purchase using paypal express checkout. Look at sandbox to find more examples.

Installation

php composer.phar require payum/payum-silex-provider payum/xxx

Note: Where payum/xxx is a payum package, for example it could be payum/paypal-express-checkout-nvp. Look at supported gateways to find out what you can use.

Note: Use payum/payum if you want to install all gateways at once.

Now you have all codes prepared and ready to be used.

Configuration

First add PayumProvider to your application:

<?php
//payum provider requires some other providers to be registered.
$app->register(new \Silex\Provider\UrlGeneratorServiceProvider());
$app->register(new \Silex\Provider\FormServiceProvider());
$app->register(new \Silex\Provider\TranslationServiceProvider());
$app->register(new \Silex\Provider\TwigServiceProvider());
$app->register(new \Silex\Provider\ValidatorServiceProvider());
$app->register(new \Silex\Provider\ServiceControllerServiceProvider());

$app->register(new \Payum\Silex\PayumProvider());

Now you can configure the gateway gateway and the storages:

<?php
use Payum\Core\Storage\FilesystemStorage;

$app['payum.security.token_storage'] = $app->share(function($app) {
    return new FilesystemStorage('/path/to/storage', 'Payum\Core\Model\Token', 'hash'),
});

$app['payum.gateways'] = $app->share($app->extend('payum.gateways', function ($gateways) use ($app) {
    $paypalExpressCheckoutGatewayFactory = new \Payum\Paypal\ExpressCheckout\Nvp\PaypalExpressCheckoutGatewayFactory();

    $gateways['paypal_ec'] = $paypalExpressCheckoutGatewayFactory->create(array(
        'username' => 'EDIT_ME',
        'password' => 'EDIT_ME',
        'signature' => 'EDIT_ME',
        'sandbox' => true
    ));
    
    return $gateways;
});

$app['payum.storages'] = $app->share($app->extend('payum.storages', function ($storages) use ($app) {
    $storages['Payum\Core\Model\Payment'] = new FilesystemStorage('path/to/storage', 'Payum\Core\Model\Payment');
    
    return $storages;
});

Prepare payment

Lets create a controller where we prepare the payment details.

<?php
class PaymentController
{
    protected $app;

    public function __constructor(Application $app)
    {
        $this->app = $app;
    }

	public function preparePaypalAction()
	{
        $storage = $this->app['payum']->getStorage('Payum\Core\Model\Payment');

        $payment = $storage->create();
        $payment->setTotalAmount(123);
        $payment->setCurrencyCode('USD');
        $storage->update($details);

        $captureToken = $this->app['payum.security.token_factory']->createCaptureToken('paypal_ec', $payment, 'payment_done');

        return new RedirectResponse($captureToken->getTargetUrl());
	}
}

Here's you may want to modify a payment_done route. It is a controller where the a payer will be redirected after the payment is done, whenever it is success failed or pending. Read a dedicated chapter about how the payment done controller may look like.
