I am having a problem getting a session variable in the function
(currentlogin) below. I can process the script and in the else statement
"print ($HTTP_SESSION_VARS['name']);" the session variable is printed but
when the function tries to print the session variable, I get an error
indicating an undefined variable.
If someone could help me out I would appreaciate it. Is there a good
tutorial on how to set and get session variables. From some of the snippets
I have read in this news group there appears to be several ways to
accomplish this.
Thanks
<?php
if (isset($HTTP_SESSION_VARS['name'])==false){
writelogin();
}
else {
//Get logged in name and display message asking user if they would
like to log out
print ($HTTP_SESSION_VARS['name']);
currentlogin();
}
function currentlogin()
{
print ($HTTP_SESSION_VARS['name']);
return;
}
?>
