I have successfully integrated PayPal. All is working fine. But I want my form to redirect to my site after a successful payment. Another question: how to get response from PayP
You can use notify_url for paypal to send a IPN response to a script on your site when a payment is made. Use this hidden field.
Now when a user pays, paypal will send a IPN to your website.
For the Return, you can use:
// After successful payment // If user cancels where to redirect to.
