Integration with Paypal

**paulocon** · 12-06-2008 11:55 AM

Hi,

I have developed a website for a client, database backend etc..

Now, users need register with the site and as part of the registration process, my client wants the users to pay the registration fee via paypal...

I have the registration process complete bar the paypal section - can anyone point me in the directin of some good tutorials/info on how to integrate with paypal.

The payment will be a once off payment - using php/mysql so need some way of a userId being passed back from paypal so I can flag the relevant record in the database as being paid...

Any help on this would be greatly appreciated.

Paul

Check out ipn - instant payment notification. You can use that to automatically email people when they pay and you can incorporate other bits and pieces into your ipn script that might activate a user account for example. I think it's possible to pass custom variables, although I haven't tried that myself.
