PayPal subscription button that POST some variables after action

I need a paypal subscription button that is able to $_POST back two variables: paypal e-mail address and if it is a subscription or cancellation of subscription. How can I do that? I do not have enough experience with paypal..

 

Hi,

I can do this, PM for details.

 

Take a look into PayPal IPN. IPN stands for Instant Payment Notification, and it posts the variables back to your listener script, so that you can utilise the details.

Take a look at http://net.tutsplus.com/tutorials/php/using-paypals-instant-payment-notification-with-php/

 

Yup, but it is sending the variables back with GET not POST...
