i want to add a line of text to the bottom of my page only if the user is not logged in. --- is there a variable which i can exploit that tells the forum if there is someone logged in or not

something along the lines of

if ($loggedin == TRUE)
someone is logged in;
else
no one is logged in, so display the text;

i was going to add this to the header or footer

Quote:

_uid constant

sorry but my php skills are obviously not what i thought they were; could you explain this a little better please as i dont understand a) what the "_" at the start is about, b)do i have to put a $ at the start or not c) why there is a space in the middle of the variable, or is contstant a type of variable or is constant the value which means there is someone logged in

if i was to use the variable in a simple if statement i was trying unsuccessfully (among other things)

if($_uid constant == TRUE)

but i get a parse error and i'm pretty sure im doing something stupid

could you suggest a solution

_uid contains the numeric id of the user, if _uid == 0 then the user you are dealing with is anonymous (non logged in user).

Hi, same topic but what about on a non-forum page ?

e.g. I have a seperate login entry point on several pages which I only want to display if the user is not already logged in.

I see I can match the fud_session_innit cookie to db.evq_sess but that does not (that I can see) tell me if they are logged in or not.

is there a quick and dirty way to get this info? e.g. I don't really want to import all the FUD globals & routines into other pages just for this snippet of data.

...or should I just shut-up & add my own session vars to the login/out routines ?

You determine if a user is logged in by reading the cookie set by the forum and then checking if session id stored in the cookie matches the data in the session table. For reference consult cookies.inc.t & users.inc.t
