redirect on session end

[samoht]

Hello all,

 

I tried to Google a answer for how to do a redirect on Session end with php but only asp came up (at least on the first 2 pages). So I thought I would ask here.

 

I would like to send users back to the home page if their session expires. I think this should be simple  - right??

 

Thanks for any help,

Add this to the top of your header include:

 

if(!isset($_SESSION['somevar'])){
   header("Location: path/to/login.php");
}

Yep, Sessions can be called on pages required using session_start(); , Note this must be the first line of every page that uses sessions, or it may not work. As well, do not output anything (echo/whitespace/html etc.) before this line of code, outside the php tags.

For some reason I get a

 

FORBIDDEN Access

(flooding) message when I use that ??

Are you pasting that code on the page that its redirecting to? If so you will be in an infinite loop.

[samoht]

yep - that would be my problem.

 

However, my site is run off of my index.php so don't I have to put this there?

You'd put it anywhere you want php to check if the session is inactive and redirect.

I am assuming that your login page is access something like this "index.php?page=login"

If I am correct, you can do this..

if ($_GET['page'] != 'login' && !isset($_SESSION['somevar'])) {
// Do the redirect
}
