RE: Temp data question

Hello Jon,

I am using the PayPal IPN to get responses from its transactions but my main
concern is a user creating an account, then has no transaction can login.
For my setup a user buys "credits" so they can still log into their account
if they run out of credits since access is now limited with no credits. I
just want to prevent new users from creating accounts when cancelling
transactions and can still login and see "behind the scenes" when in theory
only if you buy something do I want them to have an account and login.

The idea of field that gets flagged by the IPN makes sense but still the
account is created. Just don't want to end up with accounts that do nothing
or dummy empty accounts.

Thanks,

Dave

You can ask paypal to send a confirmation request after a successful
transaction (an IPN or 'instant payment notification'), so I would create
the user account as per usual, but flag it as 'unconfirmed', paypal will
include the email address in the IPN request, which you can use to look up
the user record and update it as confirmed.

cheers,

J
