Seems confusing.
-------------------------
//include.php
session_name("sessionname");
session_start();
-------------------------->>
This was added in a separate file and included that file in all the files
including index.php
In index.php I registered a variable s_authed and initialised it to 0
-----------------------------
//index.php
include "include.php";
session_register("s_authed");
$s_authed = 0; // initialize session flag
----------------------------->>
And after sign up I am authenticating the user in a separate file
and setting a flag s_authed to 1
-----------------------------
//auth.php
if(check for authentication)
{
........
$HTTP_SESSION_VARS['s_authed']=1;
}
----------------------------->>
Now in the main.php
I am checking
-----------------------------
//main.php
if($s_authed==1)
{
//Display login form code goes here
}
else
{
display "authentication required";
}
----------------------------->>
This is working fine. Even when I copy and paste the URL to another browser
it is showing authentication required page.
When I used
if (!isset($_SESSION['sessionname']))
{
//Display login form code goes here
}
in main.php
it is not working. I mean that it display the page even when I copy and
paste URL in a new browser window.
Seems like an essay :)
Why is it so.
Is that my previous method was correct or any mistakes I did?
