Hitting back on a broswer is affecting my php code

[Shadowing]

I notice a situation where if someone goes to a webpage that uses SESSIONS to load information on the page and the user then goes to another page and then hits back on the broswer the page he went back to doesnt load any of the SESSION variable i had for the page.

 

Anyone know how to fix this? at first i thought it had something to do with broswer cache but idk

Ensure you initiate the session at the very top of each of your PHP pages:

 

<?php
session_start();

//rest of your code here...
?>

thanks for the reply ianh

 

I have start session on a page that is required for every page.

but for kicks I put start session on the actual page and it still does it.

 

when someone hits back it ignores all session variables.

 

my guess is when im hitting back on the browser its not refreshing the page so no connect to server

nevermind i figured out whats wrong. What i thought was going on isnt whats going on at all. I had some code turning a SESSION into NULL
