payfast-common

Payfast common class for modules

This is the Payfast common class for modules.

Installation

You can install this module using composer:

composer require payfast/payfast-common

Aggregator

Module parameters for pfValidData()

Declare the relevant $moduleInfo values when using the pfValidData() method, for example:

$moduleInfo = [
    "pfSoftwareName"       => 'OpenCart',
    "pfSoftwareVer"        => '4.0.2.0',
    "pfSoftwareModuleName" => 'PF_OpenCart',
    "pfModuleVer"          => '2.3.1',
];

$pfValid = $payfastCommon->pfValidData($moduleInfo, $pfHost, $pfParamString);

Debug Mode

Configure debug mode by passing true|false when instantiating the Payfast\PayfastCommon\Aggregator\Request\PaymentRequest class.

$aggregatorPaymentRequest = new Payfast\PayfastCommon\Aggregator\Request\PaymentRequest(true);

Breaking Changes since v1.2.0

Namespace Changes: Payfast → Aggregator

The namespaces for several core classes have been updated to improve consistency and better align with the library's purpose. This requires updating your imports to reflect the new structure.

Class Renames

To enhance clarity and maintain consistency, some classes have been renamed. Make sure to update your code to reference the new class names.

Example of Correct and Incorrect Usage:

Correct

use Payfast\PayfastCommon\Aggregator\Request\PaymentRequest;

$paymentRequest = new PaymentRequest($testMode);

Incorrect

use Payfast\PayfastCommon\PayfastCommon;

$payfastCommon = new PayfastCommon($testMode);

Breaking Changes since v1.1.0

We have migrated from static to instance methods for the Aggregator PaymentRequest class.

For example, prior to v1.1.0 we used:

// Debug mode
define('PF_DEBUG', true);

// Module parameters for pfValidData
define('PF_SOFTWARE_NAME', 'GravityForms');
define('PF_SOFTWARE_VER', '2.8.7');
define('PF_MODULE_NAME', 'PayFast-GravityForms');
define('PF_MODULE_VER', '1.5.4');

// Calling methods on Payfast\PayfastCommon\Aggregator\Request\PaymentRequest
$pfData = PaymentRequest::pfGetData();
PaymentRequest::pflog('Verify data received');

But this has now become:

// Debug mode
$aggregatorPaymentRequest = new PaymentRequest(true);

// Module parameters for pfValidData
$moduleInfo = [
    "pfSoftwareName"       => 'GravityForms',
    "pfSoftwareVer"        => '2.8.7',
    "pfSoftwareModuleName" => 'PayFast-GravityForms',
    "pfModuleVer"          => '1.5.4',
];
$pfValid = $aggregatorPaymentRequest->pfValidData($moduleInfo, $pfHost, $pfParamString);

// Calling methods on Payfast\PayfastCommon\Aggregator\Request\PaymentRequest
$pfData = $aggregatorPaymentRequest->pfGetData();
$aggregatorPaymentRequest->pflog('Verify data received');

Gateway

Usage examples

Payment Initiate

try {
    $paymentRequest   = new PaymentRequest($merchantId, $encryptionKey);
    $response = $paymentRequest->initiate($data);
} catch (Exceptione $e) {
    echo 'Error initiating payment: ' . $e->getMessage();
}

Redirect to Gateway

echo $paymentRequest->getRedirectHTML($payRequestId, $checksum);

Query Transaction

try {
    $paymentRequest   = new PaymentRequest($merchantId, $encryptionKey);
    $response = $paymentRequest->query($payRequestId, $reference);
} catch (Exceptione $e) {
    echo 'Error querying transaction: ' . $e->getMessage();
}
