Hey All, Probably just a simple question, but I can't seem to get my scrip to work. The whole IPN stuff is working fine, and my script runs when the "VERIFIED" variable is returned. What I am having problems with is passing variables through paypal. I've tried putting them into a session, but that doesn't work either. What I need to do is have paypal accept a large number of variables and pass them straight through to the script that is run when verified is returned. Any Ideas? - paul -

You can do this the way jefree1 said or you can save your custom field for something else.

For my database of customers the unique ID is their e-mail, meaning there is no duplciate "e-mails" in the system, and I also have another field for "ppemail" (paypal email).

So the PP Transaction is stored in my mysql database, and I retrieve transactions for the user by their "ppemail" address, and use the custom field to carry other information I need as well.

Another good unique ID to use would be their phone number.

When adding customers to your database though you have to have error checking so that it WILL NOT allow duplicate entrys.
