$session['sessionurl'] no value in showthread.php - why?

[Spinball]

Folks,
I'm trying to pass the current session over to an external script near the end of showthread.php but $session['sessionurl'] has no value. Which is odd because it is used all over the place and I thought it always had a value. Any idea why not?
Thanks.

Did you make $session a global? Can you access other $session variables?

Thanks MarcoH64,
this is a slight modification to showthread.php just before the

PHP Code:

// #############################################################################
// output page 


bit at the bottom. I would have thought that the session variable would already be populated since it's being used elsewhere in the script.
I tried [sessionhash] aswell but that was empty, too.

$session['sessionurl'] only holds a value if you are not using cookies i think. Same goes for the other $session elements if i am not mistaken.

You are either using cookies, or $session.

Ah ok, Marco, so do you know how I can pass session information to an external script, please?

trying using $_SERVER['REQUEST_URI']?

one question on that, do you need it to be secure?

You should never trust any information that comes from outside a script. Always validate it before using.
