[PHP] User Control Panel (Instant donation)

Hi,

I'm not quite sure if this is the correct section, move this thread if it isn't.

Well I have been struggling with some PHP issues and ideas lately. I have been working on my own User Control Panel for my SA-MP server, the donation page has been set-up but I want the donation system to be instant.



By instant I mean you choose your donation package, you pay through PayPal and if the payment was successful, your perks will automatically be given to you.



I did search a lot, as I thought of different ways of making this system, yet I didn't get anywhere far.

My script is fully connected to mySQL and I do know about PayPal IPN.



Thanks in advance!
