best way to track varables

laeelin

I'm building a web site that has several requirements.

The site needs to be able to be duplicated on other web servers. All will share the same database. So that the shopping cart databaes will only need to be updated at one location.

I plan on createing a seprate include file for each site that will let the page know what settings to grab from the main database. This will include things like the logo, what items to sell, the style of the page, what the markup percentage is, ect.

One problem that I have had in the past it figureing out a way to pass information from one page to the next. (for example keeping track of what is in the shopping cart)

What would you think is the best real world method for keeping track of varables?

Session varables appear to be perfect, but how often will people have session cookies turned off?

any suggestions?

Thanks

If cookies are turned off, php will automaticall ad "PHPSESSID=<session ID>" to each link (<A HREF=....) but it won't font javascript & cie, but if you want to be sure the ID is transmitted, write something like that for each link :
<A HREF="show_content.php3?PHPSESSID=<?= session_id(); ?>">Show shopping cart content</A>

<SCRIPT>
function Show_Content() {
window.open("show_content.php3?PHPSESSID=<?= session_id(); ?>", "showcontentwindow", "width=.................");
}
</SCRIPT>

Etc.

I went back and reread that part of the manual (again) dont know how I missed it before, but I did =)

Thanks very much =)

I would be careful with what you store in those session variables though. If its just information about, etc you're fine. But they aren't very safe so any information you don't want to risk being intercepted should be stored elsewhere.
