When a user logs in, I guess they do enter their 'username' and 'password',
when you have verified the 'username' and 'password', do you save the id in a
session/cookie?
$query="SELECT username, fname, lname FROM core WHERE id='$id'";
You need in this case get the id, which we assume you did save in a
session/cookie, and store it in the variable $id.
If you don't do this, then you won't get the right user information, as you
really don't know who the user is after they have logged in. (there aren't
anything really wrong with your SQL statment, so it's more likely you messed
things up in your php code).
