I am not very good at PHP and a bit lost about how to do this.

I want to track those who are referred from one particular site AND complete a form. I am not sure how to start, but it seems like this is the flow:

1. Get the referrer when they arrive at my site.
2. Make this into a parameter
3. Somehow store this parameter as they browse around
4. Retrieve the parameter when they come to fill in a form

1 and 2 I can do. If I have the parameter stored somehow I can do 4.

3. I am a not sure how to achieve. Any help appreciated.
