Develop Payment Plugins

EShop supports multiple payment plugins. After being installed, the payment plugins are stored in the folder components/com_eshop/plugins/payment.

Following are steps to create a payment plugin for EShop:

Step 1: Create a .xml file to define the plugin package (example os_paypal.xml) with the structure as following:

Step 2: Create a .php file to put the code to process the payment (example os_paypal.php):

// Each payment plugin is defined as a class which is extended from parent class os_payment
class os_paypal extends os_payment
{
    * Constructor functions, init some parameters which are used in the payment method
     *
     * @param object $config to include parameters are defined in the xml file
     */
    public function __construct($params)
    {
        // Put the code here    
    }

    /**
     * This function to process payment
     *
     * @param array $data include all of information of processing order as an array            
     */
    public function processPayment($data)
    {
        // Put the code here
    }

    /**
     * This function to verify payment
     *
     */
    public function verifyPayment()
    {
        // Put the code here
    }
}

Step 3: Make a zip package include 2 above files, then login to the back-end of your site, go to EShop -> Plugins -> Payments to choose the zip package of payment plugin and install it from there.
