Session variables...?

[Anon]

I have a page with sections that the user can turn on and off at will - how do I pass those variables from one page to the next without having to append it to every URL?

I looked through the Manual and found session_register() but the accompanying info was insufficent for my small, hot, brain to do anything with 🙂

Can anybody tell me how this works. I only have to pass 2 variables...

Cheers in advance.

Tony.

session_register($variable1)
session_register($variable2)

that should do it.

using...
session_register($variable1, $variable2)

should work too.

Also remember that you must register your vars before anything is sent to the browser
and remember to use session_start on every page you want to access those vars. Technicallly the session_register function should start a session if there isn't one in progress but it's a good habit that will save complication.

PS go back to the manusl or try the tutorials on this site or www.devshed.com it will be worth your while 😉

Actually I'm pretty sure you register session variables without the dollar sign... It should be like this:

session_register('variablename');

oops, yep I forgot about leaving the dollar sign out.

Thanks for your time - I have added:

session_start();
session_register(gameType);

Everytime I refresh the page though I get the error:

Warning: Use of undefined constant gameType - assumed 'gameType' in d:\website\wwwroot\index.php on line 4

If I add the $ to the variable name I get no errors? Oh and it seems to have assigned a value to the session that now does not change when I click on a anchor link with the new value appended to it...

Hi
There's nothing wrong with the code you've posted except you need to put your var in"" like print("gameType");
You register the var without the $ sign and then access and manipulate it with the sign like print($gameType);
