[Chameleon] can you access session variables from main application .php file?

[Paul Spencer]

Ken,

Chameleon uses a different session handler than the default PHP one, you 
are likely starting a new session when hitting the Chameleon application 
page.

You have two choices at this point.  You can either:

1) start a normal php session, make a copy of the variables you need, 
close the session and start a chameleon session:


if (isset($_REQUEST['something'])) //indicates coming from application
{
   session_start();
   $var1 = $_SESSION['var1'];
   session_write_close();
}

//this starts Chameleon's session
include_once( 'path-to-chameleon.php' );

if (isset($var1))
{
   $_SESSION['var1'] = $var1;
}


2) modify your application to use Chameleon's session handler

include_once( 'path-to-chameleon/htdocs/common/session.php' );
installSessionDirectoryHandler();
initializeSession();


I didn't go look this up so I may have the wrong function names, but if 
you look in session.php you'll find it.

Cheers

Paul
