Session Variables

[crankshaft]

Hi Everyone;

My first post :)

I am trying to use session variables to pass the background colour of a page loaded into a frame using session variables:

I declare tyhe colour in the main page which loads first, this is the content in the main page and echos OK.

$_SESSION['content_color'] = "#E9E9E9";
echo $_SESSION['content_color'];

However if I echo the session variable in my loaded page in another frame I don't get anything at all!

Any ideas?

Thanx

Why don't you try putting:

session_start();

on the receiving page?

I think this is because the receiving page needs to know the variable you are using for the color.

Please correct me if I'm wrong.

You aren't wrong.

Welcome to WebmasterWorld, crankshaft.

You need to start a session for every page in which you want to set or retrieve session variables and their associated values.

Transit the session id ( SID ) in the url to other pages. Use session_start() at top of Web page code, ( before sending anything to client ) e.g.,
<a href="transit.php?<?php echo strip_tags(SID);? ">Go</a>

Great;

Thanx so much for all your feedback, adding the start session to the receiving page did the trick :)

I wanna ask, if session variables are available when we register a cookie. Or, we've to register both cookies and sessions ( if client is not accepting cookies ).

Cookies and sessions are two separate animals. Session management often uses cookies, though. Have a read through PHP's Session Handling Functions [php.net] for more information.
