Sessions in functions

[microwave]

Can anyone help me with a wee problem i have? My code goes:

<? function check_status()
{
if(session_is_registered("valid_user")
echo "You are logged in as $valid_user";
else
echo "You are not logged in";
}

the session is registered, initially on another page (the login page), but i can't access if from any function i've written. Do i need to pass the variable to the function and if i do, can people change its contents by page.php?valid_user=joe_bloggs

Hope this is clear. Many thanks

micro.

hello fellow Scot.

Why not just do the same thing without a function, and use it as an include file ? it may be easier.

// the include file: (check.php)
if(session_is_registered("valid_user") {
// the user is logged in
} else {
// the user is not logged in
}

// all other files
include "check.php";

If you really what to use a function then you need to declare the session variable as Global from inside the functions like this:

function myfuct() {
global variable name..
}
