pf::web::custom - custom code to override pf::web's behavior
pf::web::custom allows you to redefine subs in pf::web. It will never be overwritten when upgrading PacketFence.
What we are doing here is a little bit tricky: We are redefining subs in pf::web.
To do so, we are messing with typeglobs installing anonymous subs in the pf::web namespace replacing earlier implementations.
WARNING: The technique described below is for demonstration purposes only. Node categorization is better performed by the authentication modules under conf/authentication now. See pf::web::auth for more information.
Here if a particular session variable was set, we categorize the node as a guest and we set it's expiration to now + $GUEST_SESSION_DURATION. Then the normal registration code is called.
To set the particular session variable use the following: $session->param("usercategory", "guest");
Here's an example to make variables accessible to the templates globally.
Also remember that you can always use the $portalSession->stash to add variables from every location in the code (CGI's, pf::web, etc.). It's probably the best approach if what you want to inject depend on some state or user input.
