PHP session var strange value through AJAX

my code is a bit messy so I'll try to explain to you in words:

I have this index.php page that shows a random file from my files table in my database. People have the opportunity to rate these files by clicking on notes that open "vote.php" through a small AJAX pop-up.

Now here's the problem. On index.php I pull the ID from the database and output it:

$_SESSION['file_id'] = $file_id;
echo $_SESSION['file_id'];

But when I open the vote.php pop-up and write:

session_start();
echo "SID="; echo $_SESSION['file_id'];

The value is not the same! What could cause this?

Thank you very much.

You shall pass sessions variables to your AJAX requests in the form of (javascript code):

enquiry.php?' + session_name + '='  + session_id + '&vote=whaevere_you_want&foo=bar

Where session_name and session_id are javascript local variables obtained via AJAX initalizer to fetch them from a php script which is capable of providing them via PHP functions:

session_name()
session_id()

respectively

Without fixing this specific problem, I don't think $_SESSION is needed here.

Can't you open vote.php with

vote.php?file_id=xxxx

You just need to add the variable in the URL when you generate index.php.

No need for sessions here.
