Ik ben bezig met het maken van een paypal betalings systeem, alleen gaat het nog niet helemaal goed.
De hele betelingen kunnen gedaan worden en ook het bedank venster werkt goed maar paypal zou nadat de betaling voltooid is zelf een pagina moeten aanroepen waarin een email naar de beheerder gestuurd word. En dat gebeurt niet. Ik heb gebruikt gemaakt van een bestaande aypal class.
Weet iemand waarom paypal de pagina niet aanroept en/of de email niet word verstuurd?

*******************************************************************************
* 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.

Ga je script is debuggen..
wat doet de functie $p->validate_ipn() en wat return't deze als je hem aanroept.
komt die daaruberhaupt aan? staat er geen error in je log files.
daarnaast. waar test je dit, localhost? zoja, heb je wel een mailserver geinstalleerd in je installatie? Echo is gewoon iets simpels onder:
if($p->validate_ipn()) {
echo 'Validate succesvol';
en maak ook een } else { aan
met echo 'validate insuccesvol';
waar loopt je script, hoe loopt die? Dit is alleen een parse van een class die zou moeten werken. Hier kan je niet veel mee.

Een echo in dat stuk zetten heeft geen nut omdat paypal die pagina in laad en niet een bezoekers laad zien.
PS Het is niet mijn script (zoals in de bovenste regels van de class staat)
