Setting Cookie vars

peacemaker

HI,
I'd like to save several information in a session cookie when a user comes to my site.
The session should start on the first page that the user requests. That could be /index.php or /subfolder/etc/something.php.

So, no matter where on the site you start browsing my site, the session cookie should store language preference, screen width (gotten through javascript, and a third variable).

That cookie should remember the user setting throughout the site. 😉

I was think that, if a user comes to a site and the session is not started, I forward him to the site that starts the session and sets the cookie.

But how do I do that? :eek:

And how do I set a variable in a cookie?

I read that the page that starts the session (and sets the cookie) is not able to read from that cookie so it itself is displayed using the cookie data. How do I work around that?

Thank you!!!
😃

By the way, I do know that any site should be able to start the session, but is it better to farward the visitor to one specialized site that does that?

Do I use $_SESSION or session_register()? I have Php 4.3.0

Thanks.

session_register()

I don't know entirely if session_register() is the way to go...

I'm in the middle of trying to figure out some session/cookie related issues that i'm having in developing a site, and in the process, i have read here: http://us2.php.net/manual/en/function.session-register.php that says:

If you want your script to work regardless of register_globals, you need to use the $SESSION array. All $SESSION entries are automatically registered. If your script uses session_register(), it will not work in environments where register_globals is disabled.

and I recommend simply doing this:

You can also create a session variable by simply setting the appropriate member of the $_SESSION or $HTTP_SESSION_VARS (PHP < 4.1.0) array.

ie:
$_SESSION["zim"] = "An invader from another planet.";

and remember, you DO NOT have to 'globalize' (via 'global $_SESSION') in your functions, since it is a super global already.

cheers,
