Description

A payment processing module encapsulating all communications with various payment interfaces.

The application just pushes a payment request with the authorizationRequest API call. When a payment is processed, the payment module calls the selling application's authorizationResponse callback API method to notify it of the results. After payment processing is finished, the user will be redirected to the calling application's webroot, or to the URL provided by authorizationReturn result if the selling application provides it.

The payment module provides an administrative interface to list and search payment requests per module, amount, user status etc.

Features

authorizationRequest() usage example


$app = $registry->getApp(); // Calling app

$transaction_id = "myID123"; // App internal unique id

$total = 500; // Total requested amount

$params = array(); // Optional: Additional payment parameters, like user details (name, address etc..)

// Check if any authorization method exits and is linked to this

$authorization_methods = $registry->call('payment/getMethods', array($app));

if ($authorization_methods instanceof PEAR_Error) {

    echo sprintf(_("Authorization error. %s"), $authorization_methods->getMessage());

    exit;

}

// Push an paymnet authorization request

$authorizationID = $registry->call('payment/authorizationRequest',

                                    array($app, $transaction_id, $total, $params));

if ($authorizationID instanceof PEAR_Error) {

    echo sprintf(_("Authorization error. %s"), $authorizationID->getMessage());

    exit;

}

// Redirect to paymnet system

// $redirect_url = $registry->link('payment/show', array('id' => $transaction_id, 'module' => $app));

$redirect_url = $registry->link('payment/show', array('id' => $authorizationID));

header('Location:' . $redirect_url);

exit;
