Securing a webpage from re-entry

[url removed, login to view]

I have a webpage that users pay to enter. After they pay they are taken to the above url and then to a calculation oage.

The last eight characters of the above url is the receipt number for the payment KG8S0KP4 , IN THIS CASE. This code should not be used more than once.

I am after quotes for a PHP programmer to secure the site to make sure that the same code is not used more than once, and that the page following this url which is entered from this page is not accessed without a valid receipt number.

The url of the next page is [url removed, login to view]

I do not want this page displayed unless the user has a valid receipt code that has not been used before, at least in the last six months.

This is the calculation page that the user is paying to use, each time he uses it.

After he pays he goes to a page like

[url removed, login to view]

and is then linked to the calculation page.

You need to setup a PHP program to ccheck the validity of the code from a database of codes and dates to make sure that the same code hasnt been used in the last six months.

I am using [url removed, login to view] to take the payments by credit card which will soon have PayPal added.

clickbank provides the receipt code on the Thank You page.
