/*******************************************************************************
* PHP Paypal IPN Integration Class
*******************************************************************************
* Author: Micah Carrick
* Email: email@micahcarrick.com
* Website: http://www.micahcarrick.com
*
* File: paypal.class.php
* Version: 1.3.0
* 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:
* v1.3.0 [10.10.2005] - Fixed it so that single quotes are handled the
* right way rather than simple stripping them. This
* was needed because the user could still put in
* quotes.
*
* v1.2.1 [06.05.2005] - Fixed typo from previous fix :)
*
* v1.2.0 [05.31.2005] - Added the optional ability to remove all quotes
* from the paypal posts. The IPN will come back
* invalid sometimes when quotes are used in certian
* fields.
*
* v1.1.0 [05.15.2005] - Revised the form output in the submit_paypal_post
* method to allow non-javascript capable browsers
* to provide a means of manual form submission.
*
* v1.0.0 [04.16.2005] - Initial Version
*
*******************************************************************************
* DESCRIPTION:
*
* NOTE: See www.micahcarrick.com for the most recent version of this class
* along with any applicable sample files and other documentaion.
*
* 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.
