Guardian-Mage Posted May 27, 2008 Share Posted May 27, 2008 I would like double security, I want to encrypt my buttons dynamically with PHP, and verify the payment as it goes through (using IPN). Is it possible to do both, and how would send back an invalid message to Paypal. For example, someone buys something, Paypal tells me what they bought, my script finds the price invalid, and tells Paypal to redirect back to my error page which tells the user the price is wrong(or auto corrects it). Any help please? Link to comment https://forums.phpfreaks.com/topic/107367-paypal-with-my-shopping-cart/ Share on other sites More sharing options...
