general question on dynamic cms, with files

[businessman332211@hotmail.com]

I have set up the framework almost for a program. I know it's not a good idea to create new tables dynamically(database tables). At this point though, I have a lot of information going throughpaypal, and coming back to paypal's IPN system. The thing is if I am not careful this could be riddled with security issues, when they finally payout. I am taking either template1.php or template2.php depending on which one they have chosen(more are getting added later), and I am opening it, reading the contents of it, and saving it in a variable. Then I need to find a way to create a cms for it, I need to get the cms put within the file information somehow, as well as decide what table structure in the database I can use for something like this. So they will be able to login to there administration area later on, and do what they need to do??
