session id

[redarrow]

Advance thank you.

Is it possable to session_srart and then id = session id and then use that session id to update all other fields but with only using a set session id.


example
[code]
session_start()

id=($_session["id"]);

$db=mysql_connect("localhost");
mysql_select_db("whatever",$db);
$query="update whatever set name='$name' , email='$email' , number='$number' where id='$id'";
$result=mysql_query($query);
[/code]

know when a user post there information the session id identifies the user id of field so can i get the other fields like name email ect ect to update with only the session id set.

thank you.

$id = session_id();
