[Resolved] Variables across pages

Bah__Name

I have some session variables for each user but I want to preserve them across pages. I've tried finding the answer in the search here. It looks like I pass an array containing the variables in the URL for each page, is this right?

Can I have an array which contains other arrays as elements?

My array may include imagestream variables. What is the memory limit for this kind of stuff, is it the server or the clients memory..?

PHP will check automatically (if session.auto_start is set to 1) or on your request (explicitly through session_start() or implicitly through session_register()) whether a specific session id has been sent with the request. If this is the case, the prior saved environment is recreated.

SO, in answer to your question, all you have to do is start the session to make it so you can read the variables for every page after the page you set the variable... should make sense... if not, read the below page.

I believe you're talking about multi-dimensional arrays. if this is the case. then yes, you can have them. i'm not sure what you mean by 'other arrays as elements'. for further reading, checkout:

as far as the last question goes... this windows been open all day and i just remembered i started the reply a long time ago so i'm not gunna finish it 🙂

The whole idea behind sessions is that they span multiple pages.

if you have registered session vars, and you have session_start() at the TOP of a page, they are made available in the array

$_SESSION[var]

To make it easier on yourself, set them to simple vars

$user_permissions = $_SESSION['userlevel'];

or something like this

Thanks for the links.

I put a sessions_register(MyVar) at the top of my script, between the <?php and ?>, then wrote another script underneath on the same page, and the variable was preserved. But when I added a URL to another page, the variable wasn't... 😕

Yes, Multi-dimensional arrays. I want to specifically be able to do

$array1[2] = $array2;

of course is the vari available on the same page, coz it's one script and one page. I guess "adding a new url" means clickin on a link to go to some other page, doesn't it?
So it seems either your session config is wrong or u don't code it properly.... Do you have session_start() at the top of "the other page"?
And sessions_register(MyVar) should be session_register($MyVar), else it cannot work at all. Also note that u gotta access the var via $_SESSION on the other pages.
maybe check this out first and then post agian if it did not solve the problem.
