Session -> if Problem

[spighita]

Hello:
On my first page I have a session start. I`m trying to solve a security problem cause I would like only for some people to view it.

The way I'm solving it is with sessions. But suppose I call the page.php like without a session my session register won't work.

        Cause When I call the session and ask if the condition is met then do load the page if not echo a message. So the way I`m doing this is 

$login=$HTTP_SESSION_VARS['login'];

That calls the person who is logged for example

so I ask if ($login!="") then do this if not
echo a message.

I also ask if echo $login and nothing appears

So why won`t my condition work. Any ideas on how to solve my little security problem

Thanks in advance for anyone who helps.

start all the pages implied in the authentication with the line session_start();
register all session variables with session_register('var');
try to recover the variable values using $_SESSION['var'] instead.
hope these tips helps.

Hi,

if you use $SESSION['variable'] for the first time on a variable it will be registered in the session automatically, you don't need to use session_register() anymore if you use $SESSION 🙂

if you are not sure if your variable has been set or not... use this to avoid errors

if ( isset($_SESSION['var_name']) ) { }

that's a doubt i had when changing my scripts to the new $COOKIE, $SESSION... superglobals (Now i know i have innecessary lines in my scripts) 🙂
