v3.2 - 2021-06-01

Omnipay 3.2 is compatible with PHP8. This is done by upgrading the test suite to PHPUnit 8/9, with the release of omnipay/tests v4 and omnipay/common v3.1. This change is primarily for gateway developers, to make it possible to actually test PHP8, but they will need to upgrade their tests to use PHPUnit 9 (the currently supported PHPUnit version).

v3.1 - 2020-10-29

Omnipay 3.1 uses Guzzle 7 by default (using the Guzzle 7 adapter). This doesn't change omnipay-common because they will work with any compatible Http Client. The minimum PHP versions is bumped to 7.2 because of this.

v3.0 - 2018-05-14

Omnipay 3.0 focuses on separation of the HTTP Client, to be independent of Guzzle. This release brings compatibility with the latest Symfony 3+4 and Laravel 5. The breaking changes for applications using Omnipay are kept to a minimum.

The omnipay/omnipay package name has been changed to league/omnipay

Upgrading applications from Omnipay 2.x to 3.x

Breaking changes

  • The redirect() method no calls exit() after sending the content. This is up to the developer now.
  • An HTTP Client is required. Guzzle will be installed when using league/omnipay, but otherwise you need to required your own implementation (see PHP HTTP Clients)
  • The omnipay/omnipay package name has been changed to league/omnipay and no longers installs all the gateways directly.

Added

  • It is now possible to use setAmountInteger(integer $value) to set the amount in the base units of the currency.
  • Support for Money for PHP objects are added, by using setMoney(Money $money) the Amount and Currency are set.

Upgrading Gateways from 2.x to 3.x

The primary difference is the HTTP Client. We are now using HTTPlug (http://httplug.io/) but rely on our own interface.

Breaking changes

  • Change typehint from Guzzle ClientInterface to Omnipay\Common\Http\ClientInterface
  • $client->get('..')/$client->post('..') etc are removed, you can call $client->request('GET', '').
  • No need to call $request->send(), requests are sent directly.
  • Instead of $client->createRequest(..) you can create+send the request directly with $client->request(..).
  • When sending a JSON body, convert the body to a string with json_encode() and set the correct Content-Type.
  • The response is a PSR-7 Response object. You can call $response->getBody()->getContents() to get the body as string.
  • $response->json() and $response->xml() are gone, but you can implement the logic directly.
  • An HTTP Client is no longer added by default by omnipay/common, but league/omnipay will add Guzzle. Gateways should not rely on Guzzle or other clients directly.
  • $body should be a string (eg. http_build_query($data) or json_encode($data) instead of just $data).
  • The $headers parameters should be an array (not null, but can be empty)

Examples:

// V2 XML:
 $response = $this->httpClient->post($this->endpoint, null, $data)->send();
 $result = $httpResponse->xml();

// V3 XML:
 $response = $this->httpClient->request('POST', $this->endpoint, [], http_build_query($data));
 $result = simplexml_load_string($httpResponse->getBody()->getContents());
// Example JSON request:

 $response = $this->httpClient->request('POST', $this->endpoint, [
     'Accept' => 'application/json',
     'Content-Type' => 'application/json',
 ], json_encode($data));
 
 $result = json_decode($response->getBody()->getContents(), true);

Testing changes

PHPUnit is upgraded to PHPUnit 6. Common issues:

  • setExpectedException() is removed
// PHPUnit 5:
$this->setExpectedException($class, $message);

// PHPUnit 6:
$this->expectException($class);
$this->expectExceptionMessage($message);

  • Tests that do not perform any assertions, will be marked as risky. This can be avoided by annotating them with @doesNotPerformAssertions

  • You should remove the Mockery\Adapter\Phpunit\TestListener in phpunit.xml.dist

v2.0.0 - 2013-11-17

Package Separation

As of 2.0, Omnipay has been split into separate packages. Core functionality is contained within the omnipay/common repository, and all gateways have their own repositories. This means that if your project only requires on a single gateway, you can load it without installing all of the other gateways. All officially supported gateways can be found under the Omnipay GitHub organization.

If you want to install all gateways, you can still use the omnipay/omnipay metapackage in composer.json:

{
    "require": {
        "omnipay/omnipay": "~2.0"
    }
}

Alternatively, if you want to migrate to an individual gateway, simply change your composer.json file to reference the specific gateway (omnipay/common will be included for you automatically):

{
    "require": {
        "omnipay/paypal": "~2.0"
    }
}

Breaking Changes

The GatewayFactory class can no longer be called in a static fashion. To help those who want to use dependency injection, you can now create an instance of GatewayFactory:

$factory = new GatewayFactory();
$gateway = $factory->create('PayPal_Express');

The following code is invalid and will no longer work:

$gateway = GatewayFactory::create('PayPal_Express'); // will cause PHP error!

If you want to continue to use static methods for simplicity, you can use the new Omnipay class:

// at the top of your PHP file
use Omnipay\Omnipay;

// further down when you need to create the gateway
$gateway = Omnipay::create('PayPal_Express');

Behind the scenes, this will create a GatewayFactory instance for you and call the appropriate method on it.

Additions

Omnipay now supports sending line-item data to gateways. Currently this is only supported by the PayPal gateway. Line item details can be added to a request like so:

$request->setItems(array(
    array('name' => 'Food', 'quantity' => 1, 'price' => '40.00'),
    array('name' => 'Drinks', 'quantity' => 2, 'price' => '6.00'),
));

For more details, see the pull request.

Omnipay now also supports modifying request data before it is sent to the gateway.. This allows you to send arbitrary custom data with a request, even if Omnipay doesn't support a parameter directly. To modify the request data, instead of calling send() directly on the request, you may use the new sendData() method:

// standard method - send default data
$response = $request->send();

// new method - get and send custom data
$data = $request->getData();
$data['customParameter'] = true;

$response = $request->sendData($data);
