Paypal IPN

Hi,

With the Paypal IPN, is it possible to send Custom Variables so that when the return page is shown, the variables are sent so they can be used?

You can send on/os pairs.

on0=customername
os0=John+Doe
on1=customercity
os1=Detroit

afaik, you can only send 2 of those on/os pairs.

or maybe im confusing that with something else?

I think so.
If thats the case you can also send char delimited data like
os0 = "name|email|address|".... and process back that when you get it.

yeah that's another option, just use some unlikely symbol between values (just avoid &, !, $, #, |, \, basically all the ones that have special meanings in programming) to be on the safe side. i like to use ~ or even a combination like ^~^ and then use php's explode("^~^", $_POST['os0']) or w/e it would be to split it into an array.

when i do it i do something like:

$_SESSION['custom'] = $_SESSION['login'] . '|' . $_SESSION['pass1'] . '|' . $_SESSION['user_email'];

Then on the return I just blow it up!

$data = $_SESSION['custom'];
list($_SESSION['login'], $_SESSION['pass1'], $_SESSION['user_email']) = explode("|", $data);
