Subject: RE: [Xerte] Passing SESSION variable<br>
<br>
For any PHP script to have access to session variables, you must first<br>
invoke the session handler. Open the php script in question and look for<br>
session_start(); If it is not there, add it near the top of the script,<br>
before any attempt to read or set session variables. Once you have that,<br>
you can see what session variables are available by using<br>
print_r($_SESSION);<br>
<br>
As Dave mentioned, you must accept cookies for session variables to<br>
work.<br>
<br>
It sounds like your PHP is set up to not show errors. In those<br>
situations a fatal error will result in a blank page. During<br>
development, it's really nice to know what errors may be happening, so<br>
you may want to override the php.ini settings while you are<br>
troubleshooting. You can do this on a script-by-script basis with the<br>
following:<br>
<br>
ini_set('display_errors', 1);<br>
error_reporting(E_ALL);<br>
<br>
You will want to comment those lines out once you've got it working.<br>
<br>
Hope that helps.<br>
<br>
