README

Simple bundle for implementing Omnipay in your Symfony application.

Versions

Install

Via Composer

$ composer require colinodell/omnipay-bundle

Enable the bundle in your AppKernel.php:

new ColinODell\OmnipayBundle\OmnipayBundle(),

Usage

This bundle provides a new service called Omnipay. It contains a single method get(), which returns a fully-configured gateway for you to use:

$stripe = $this->get('omnipay')->get('Stripe');

$paypal = $this->get('omnipay')->get('PayPal_Express');

You can then use these gateways like usual.

Note: Gateways are "cached" - calling get('Some_Gateway') multiple times will always return the same object.

Configuration

Gateways can be configured in your app/config/config.yml file

omnipay:
    methods:
        # Your config goes here

For example, to configure the Stripe and PayPal Express gateways:

omnipay:
    methods:
        Stripe:
            apiKey: sk_test_BQokikJOvBiI2HlWgH4olfQ2

        PayPal_Express:
            username:     test-facilitator_api1.example.com
            password:     3MPI3VB4NVQ3XSVF
            signature:    6fB0XmM3ODhbVdfev2hUXL2x7QWxXlb1dERTKhtWaABmpiCK1wtfcWd.
            testMode:     false
            solutionType: Sole
            landingPage:  Login

NOTE: You should probably consider using parameters instead of storing credentials directly in your config.yml like that.

The method names should be whatever you'd typically pass into Omnipay::create(). The configuration settings vary per gateway - see Configuring Gateways in the Omnipay documentation for more details.

Registering Custom Gateways

Custom gateways can be registered via the container by tagging them with omnipay.gateway:

# services.yml
services:
    my.test.gateway:
        class: Path\To\MyTestGateway
        tags:
            - { name: omnipay.gateway, alias: MyTest }

# config.yml
omnipay:
    methods:
        # Reference the gateway alias here
        MyTest:
            apiKey: abcd1234!@#

You can then obtain the fully-configured gateway by its alias:

$this->get('omnipay')->get('MyTest');

Additional configuration and customization

Default gateway

Add default gateway key to your config:

# config.yml
omnipay:
    methods:
        MyGateway1:
            apiKey: abcd1234!@#
        MyGateway2:
            apiKey: abcd45678!@#

    default_gateway: MyGateway1

You can now get default gateway instance:

$omnipay->getDefaultGateway();

Disabling gateways

If need to disable a gateway but want to keep all the configuration add disabled_gateways key to the config:

# config.yml
omnipay:
    methods:
        MyGateway1:
            apiKey: abcd1234!@#
        MyGateway2:
            apiKey: abcd45678!@#

    disabled_gateways: [ MyGateway1 ]

MyGateway1 gateway will be skipped during gateway registration now.

Customizing Omnipay service

If you need specific gateway selection mechanism or need to get multiple gateways at once consider to extend default Omnipay service. Create your custom Omnipay class, extend it from base class and add custom getters. For example, you might want to get all gateways which implement some interface.

<?php

// AppBundle/Omnipay/Omnipay.php

namespace AppBundle\Omnipay;

use AppBundle\Payment\Processing\Gateway\VaultAwareGateway;
use ColinODell\OmnipayBundle\Service\Omnipay as BaseOmnipay;
use Omnipay\Common\GatewayInterface;

class Omnipay extends BaseOmnipay
{
    /**
     * @return VaultAwareGateway[]
     */
    public function getVaultAwareGateways()
    {
        return array_filter($this->registeredGateways, function (GatewayInterface $gateway) {
            return $gateway instanceof VaultAwareGateway;
        });
    }
}

#services.yml
parameters:
    omnipay.class: AppBundle\Omnipay\Omnipay

Now you should be able to get vault-aware gateways in your application:

foreach ($omnipay->getVaultAwareGateways() as $gateway) {
    $gateway->saveCreditCard($creditCard); // assuming saveCreditCard is a part of VaultAwareGateway interface
}

Initialize gateways on registration

By default gateway is initialized only when you call get() method. If you use custom getters (like getVaultAwareGateways from example above) with $this->registeredGateways inside you might want to initialize them automatically during registration. Simply add appropriate config key:

# config.yml
omnipay:
    methods:
        MyGateway1:
            apiKey: abcd1234!@#

    initialize_gateway_on_registration: true
