[Xerte] Passing SESSION variable

[Paul Swanson]

Just poked around on my system where I have an old copy of moodle
installed. I'm using Xerte stand-alone, not XOT, and we aren't using
moodle. Anyway, I found a folder off my root named moodledata, and in
there is a folder named sessions where moodle seems to be storing it's
session cookies. Could the problem be that moodle uses its own folder
for sessions, rather than the folder specified in php.ini?

edit.php has a session start line in, believe me, i know, it couldn't
work without one.

 

When i tried to integrate with moodle it worked up until edit, and i
could never get edit to to work.

 

You can try adding session_start(); print_r($_SESSION); at the top of
the code, but when i did that i still got nothing.

 

I don't know enough about moodle, but i assumed when moodle runs
session_start, is passes through some parameters to set itself up, or
the way moodle passes session ids is different to toolkits.

 

I would hunt for a session_start function call in the moodle code.

For any PHP script to have access to session variables, you must first
invoke the session handler. Open the php script in question and look for
session_start(); If it is not there, add it near the top of the script,
before any attempt to read or set session variables. Once you have that,
you can see what session variables are available by using
print_r($_SESSION);

As Dave mentioned, you must accept cookies for session variables to
work.

It sounds like your PHP is set up to not show errors. In those
situations a fatal error will result in a blank page. During
development, it's really nice to know what errors may be happening, so
you may want to override the php.ini settings while you are
troubleshooting. You can do this on a script-by-script basis with the
following:

ini_set('display_errors', 1);
error_reporting(E_ALL);

You will want to comment those lines out once you've got it working.

Hope that helps.

Paul
