PHP session var strange value through AJAX

Question

Hello guys,

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.

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.
