Hi, I know that this isn't a new topic. However, I couldn't find an answer to it. I have read some information on Paypal Developer and PDT/IPN...etc I briefly understand we need to verify the TX transaction ID and GET the information from it. However, I cannot find a sample PHP script (like a tutorial) that guides you step by step. I find the information broken into many pieces over the internet, or simply Paypal developer is for advance user. Basically, once we have created a button, buyer completes a purchase, Paypal redirects the buyer back to our website (assume I have turned on all the PDT and other settings), then how can I retrieve the buyer's email? How can I display the buyer's email on the thank you page? Thank you for the purchase. An email has been sent to xxx @ example.com Thanks for the advice.
