Criando script de pagamento

08-06-2011 14:07

Olá boa tarde amigos.
Eu estou " tentando" criar um sistema de pagamento como MOIP, PAGSEGURO. etc.
Usando essa interface de código pronta. (Sistema que estou usando é opensource mas ja me deu essa estrutura )

<?php /******************************************************************************* * PHP Paypal IPN Integration Class ******************************************************************************* * Author: Micah Carrick * Email: email@micahcarrick.com * Website: http://www.micahcarrick.com * * File: paypal.class.php * Version: 1.00 * Copyright: (c) 2005 - Micah Carrick * You are free to use, distribute, and modify this software * under the terms of the GNU General Public License. See the * included license.txt file. * ******************************************************************************* * VERION HISTORY: * * v1.0.0 [04.16.2005] - Initial Version * ******************************************************************************* * DESCRIPTION: * * This file provides a neat and simple method to interface with paypal and * The paypal Instant Payment Notification (IPN) interface. This file is * NOT intended to make the paypal integration "plug 'n' play". It still * requires the developer (that should be you) to understand the paypal * process and know the variables you want/need to pass to paypal to * achieve what you want. * * This class handles the submission of an order to paypal aswell as the * processing an Instant Payment Notification. * * This code is based on that of the php-toolkit from paypal. I've taken * the basic principals and put it in to a class so that it is a little * easier--at least for me--to use. The php-toolkit can be downloaded from * http://sourceforge.net/projects/paypal. * * To submit an order to paypal, have your order form POST to a file with: * * $p = new paypal_class; * $p->add_field('business', 'somebody@domain.com'); * $p->add_field('first_name', $_POST['first_name']); * ... (add all your fields in the same manor) * $p->submit_paypal_post(); * * To process an IPN, have your IPN processing file contain: * * $p = new paypal_class; * if ($p->validate_ipn()) { * ... (IPN is verified. Details are in the ipn_data() array) * } * * * In case you are new to paypal, here is some information to help you: * * 1. Download and read the Merchant User Manual and Integration Guide from * http://www.paypal.com/en_US/pdf/integration_guide.pdf. This gives * you all the information you need including the fields you can pass to * paypal (using add_field() with this class) aswell as all the fields * that are returned in an IPN post (stored in the ipn_data() array in * this class). It also diagrams the entire transaction process. * * 2. Create a "sandbox" account for a buyer and a seller. This is just * a test account(s) that allow you to test your site from both the * seller and buyer perspective. The instructions for this is available * at https://developer.paypal.com/ as well as a great forum where you * can ask all your paypal integration questions. Make sure you follow * all the directions in setting up a sandbox test environment, including * the addition of fake bank accounts and credit cards. * ******************************************************************************* */ class paypal_class { var $last_error; // holds the last error encountered var $ipn_log; // bool: log IPN results to text file? var $ipn_log_file; // filename of the IPN log var $ipn_response; // holds the IPN response from paypal var $ipn_data = array(); // array contains the POST values for IPN var $fields = array(); // array holds the fields to submit to paypal function paypal_class() { // initialization constructor.

Porém não estou conseguindo criar ou integra o moip nele. Alguem pode me auxiliar nisso?
Obrigado =D
