I'm a Java developer who has been thrown into joomla and hikashop to fix a problem. Never touched either or PHP even, but I can follow most languages. I'm searching through to figure out how to accomplish this, but I ask for help please! There's a cart, when it's submitted to paypal for payment, the amounts are correct and once payment is made, the system registers the payment confirmation. It seems that there's a "return to ..." link on the paypal site that actually triggers the email to send the code to the customer. If they don't click the link, the email isn't generated. Also, there's a shop field that doesn't populate unless they click the link. I need to generate the email when payment confirmation is received from paypal and also populate that field. Any help please?
