/******************************************************************************* * PHP Paypal IPN Integration Class

- 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', '[email protected]');
- $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: *
- 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. *
- 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.
