php - Paypal: How to display payer's email on the thank you page?
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 understand we need to verify the TX transaction ID (Success) before GET the information from it.
Basically, once we have created a button, buyer completes a purchase, Paypal redirects the buyer back to our website (assuming 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
Is the coding at this page still relevant (update to date) PayPal: pass the email address to the return/"thank you" page
Thanks for the advice.
