Newbie Question: How to pass a seed variable from index page to inner page

I have an affiliate site and need to better track my ad campaign on PPC. I'm sending traffic to a php page which passes the keyword as a seed variable. Then I've been putting making the sid for all of my links retreive the keyword from the url. I lose a lot of information though because if they click to a second page to get a better review, I lose the seed variable and the sid in the affiliate links is blank.

How can I fix this?

 

Well, you'd just put it in a cookie or in the session.

 

well you need to store that info somewhere... cookie,file or any other way that is working for you.

 

As said earlier, cookies/sessions are a very good and simple solution!

 

thanks. does anyone have information on how to accomplish this?

 

Just do this on the first page:

session_start();

$_SESSION['seed'] = $_GET['keyword']; //or whatever

PHP:

Second page:

session_start();

echo $_SESSION['seed']; //if you need to output it again

PHP:

 

thanks for the help!
