Premium membership system?

[eluser]nitrammit[/eluser]
I'm trying to offer members on my site the chance to upgrade their account to "Pro" status for either 1, 3, 6 or 12 months. I understand the CodeIgniter side of things - I know I need to place members into a group and set expiration dates etc, but how exactly do I handle payments, confirm they have been made and so on?

I would like to use Paypal, but yeah, I have never built something like this before.

Thanks!

For Paypal you need the IPN.
This is not hard, you can test the IPN through Paypal SandBox,
this way you don't need to use real money.

good luck.

You might wanna have a look at
CodeIgniter Payments

Looks pretty massive even though it seems to be updated for just 2.x but not within the last few months.
