Losing session variables on subsequent pages

Any session variables stored by your mySQLi behaviors get stored in the browser as expected. However, any sessions store on a given page using typical PHP code method ($_SESSION['ReturnAID'] = $User->getColumnVal("AID"); .. for example) store fine and can be echoed on the page, but as soon as I go to the next page (which also contains the mySQLi behavior to build a recordset filtering on that session variable) comes up blank. I can echo the variable on the secondary page, and it's empty! Like it's dropping that value after the transition - though the mySQLi stored sessions are definitely still there! Any ideas???

Side note, even if I set the session variable to a hard-coded value, it's still being dropped on the next page. We customized your included mySQLi support obj files on this site, and I'm hoping something we did didn't kill this function???

You may need to add this to the top of the page before referencing session variables:

<?php
@session_start();
?>

Session variables will appear blank until the session is started.

Hi Ray, you built that into your mySQLi files already though, yes? As long as any of your mySQLi behaviors are applied to the page, session support should already have been started, yes?

Our code will start the session, but it can close it after as well. It is suggested to close sessions when they aren't in use because it can speed up processing particularly when using AJAX. Try adding @session_start() above the line where you are setting your session variables. Maybe it is closed so they won't store properly.

That solved it. I'm not sure why setting session_start at the top of the page didn't fix it, but adding it in the same code where the variables are being set does. Any particular insight is appreciated.

I'm sure we are closing the session in the code above somewhere for efficiency. A single start will make all the session variables saved previously available on the page and the session can (and should) then be stopped if you aren't saving any more. If you are ever saving a session variable it is good to add a session start above and session_close() below.
