Payment Plug-ins | JoomlArt

Developing and get the payment plugins installed for your JobBoard(JB) component to vary the payment methods without the need of digging into the core codes. In quickstart package, JB has “Paypal payment plugin” as default payment method. You can download more payment plugin for JB from our forum at: FORUM LINK. We have recently integrated the popular payment gateways such as Paypal, MoneyBooker, Authorize and offline payment named Wirebank. In case, all those payment plugins do not seem to work out with your own preferable payment gateways, this guide is aiming to show you How-to develop the Payment plugins that fit you best.

Note: In this guide, we'll be using the payment plugin "Authorize" as an example for better understanding on the guide. When you are ready to develop your own, you only need to replace the "authorize" name with your own plugin's name, and this should be kept consistent in all the files.

File/Folder structure

This How-to provides you the basic understanding of what you should carry out to develop your own plugin. Most plugins consist a single code file, however in order to install the plugin correctly, its code must be packed as a zip format file which can be processed/installed by the JB Payment installer.

Creating the "manifest" file

The manifest file is served to define all the available information about your plugin, such as, your plugin's name, author, version, description (user guide, tutorial), etc...

File: authorize.xml

<?xml version="1.0" encoding="utf-8"?>

<extension version="2.5" type="plugin" group="payment" method="upgrade">

   <name>Authorize.Net</name>

Creating Plugin

Each plugin has to have one php file and a respective file name format in xml file. In the php file, you need to define a class with the required methods to handle the payment events.

Below is a sample code of a payment class and a list of required methods for each.

File: authorize.php

class authorize extends JObject {

   /** for any initialization **/
   function __construct($config) {  … }

   /**
     * Generate HTML code that will insert the payment configuration form in the back-end.
     * In addition, you can also configure your plugins' settings
     * such as your API key and merchant ID.
     **/
   function config_form() { … }

   /**
    * data preparation for checkout page
    *
    * @param array $transaction - transaction info
    */
   function go_checkout($transaction)  { … }

   /**
    * Assign params for checkout form
    *
    * @param array $transaction
          **/
   function assign_params($transaction)  { ...    }

   /**
    * validate post back from payment gateway
    **/
   function check_payment() { ...    }

   /**
    * handle in succeeded case
    **/
   function payment_return() { … }

   /**
    * handle in cancelled/failed case
    **/
   function payment_cancel() { … }

          /**
    * you can declare more methods for your class, if necessary.
    **/

}

If your plugin has more files or use 3rd party library, you need to create a folder name "authorize" and put all your files under this particular folder. Then, you can include these files into your plugin with the following code snippet:</div> authorize/

require_once dirname(__FILE__) . '/authorize/lib/shared/AuthorizeNetRequest.php';
require_once dirname(__FILE__) . '/authorize/lib/shared/AuthorizeNetTypes.php';
require_once dirname(__FILE__) . '/authorize/lib/shared/AuthorizeNetXMLResponse.php';
require_once dirname(__FILE__) . '/authorize/lib/shared/AuthorizeNetResponse.php';
require_once dirname(__FILE__) . '/authorize/lib/AuthorizeNetSIM.php';

Creating the installation file

The installation file aims to support you install the plugins, or your plugins with the sample data, or just about anything else you wish to define along with the installation. The installation file must be named as: authorize.install.php

Creating the language file

The language file is to define your plugin's language texts and is named as: en-GB.plg_payment_authorize.ini

Summary

To sum up, your payment plugin should include those below elements:

Element	Effect
authorize.xml	Required
authorize.php	Required
en-GB.plg_payment_authorize.ini
authorize.install.php
authorize
