Sorry, Jerry, you missed my question.
Send the form to PayPay is to interface with PayPal's API
with the form's ACTION line.
And since it's an API, PayPal has a way to let the user click on
"Return to bla bla".
In essence, the task will accomplish two things:
A) link the user/buyer to PayPal to make a payment
B) back to my site with a special URL that give the buyer the info
including the software download link (but this link would expire in 24
hours).
Absolutely no need whatsoever with a database for this, it would be
totally overkill.
