How to get user id using php at a page added by ajax ?

S

New member
I can get the id of that user which profile I'm visiting.
If I'm at the user's profile page who's id is 3

http://localhost/post/profile.php?id=3

I can get all information of the user 3. But on the same page I use some ajax and link it to another php file.
How can I get that user id on that page which is linked by the ajax?
Code is here.

profile.php

<html>
<head>
<script type="text/javascript" src="jquery-1.6.4.js"></script>
<script type="text/javascript" src="jquery.elastic.js"></script>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Wall Post</title>
<script type="text/javascript">

......CODE HERE, I REMOVED DUE TO SHORT CHARACTER LIMIT...........

$.ajax({
type: "POST",

url: "status_update.php",

data: DATA,
cache: false,
success: function(data){
$(data).prependTo(".load_status_out").slideDown("slow");
$(".loading").hide();
$(".input_box").val("So what's on your mind?").css("color","808080").css("height","30px");
}
});
}
return false;
});
});
</script>
</head>

$id = $_SESSION['id'];
