Hard to explain in the topic.

Basically I need to know what user is accessing a page/hyperlink.

I am trying to integrate Gallery2 into FudForum, for authentication and thus having one user base to work from and maintain.

To do this you have to create an "Entry Point" to Gallery which is basically a php file that allows an already authenticated user to be acknowledged by Gallery as that user and auto logged in as such so the user doesn't have to login again.

But to do this I need to pass to Gallery [in the php code] what user is trying to access the Gallery.

I can't seem to see a way to do this in the API. Closes thing is the function to return who is online, but that's not specific enough for whats needed here.

Anyone got any ideas ?

The idea is that you store user id inside something like a cookie, with a validation token and use the fud_fetch_user() to fetch user based on this ID.

Hmmmmm ok I am lost.

FudForum uses a cookie currently ?

How would you tackle this problem Ilia ?

I guess this can be answered by asking .... how does FudForum know, after a user has logged in, that it is indeed that same user clicking on different links, visiting different forums and giving that user the permissions all along.

Sounds fundamental to a forum and many other online software, but an area I have never dealt with before.

There must be a variable, global [?], that holds this information ?

FUDforum uses either a cookie or a URL session to keep track of the user.

FUDforum stores the session id inside the cookie and then uses database to validate this session id.

So I can compare with a session ID in the Database ? But how would I find out what users is clicking on a URL ? Say to a private forum that only certain users have access to ?

I can't see how to access this info using the API. Am I missing something ?

The permission in FUDforum are enforced by group permissions system that queries the group_cache table using the user's id and performs checks on the users_opt bitmask

So how do I pass onto Gallery2 what user is trying to access the gallery, if the user trying to go to the Gallery is logged on currently ?

Well, you use FUDAPI to fetch the user credentials based on the user's sessions. In fact you can do so via a simple query select * from fud26_ses where ses_id=[session_id]; without even using fudapi. To fetch the user details simply add INNER JOIN users u ON u.id=fud26_ses.user_id
