Or even (mysql_fetch_assoc())['id'] :-)

Firstly, id isn't in the field list. Only login_name is. But that's
semantic, not syntax.

But you shouldn't dereference the return value of mysql_fetch_assoc()
without first checking it for success:

$res = mysql_fetch_assoc(mysql_query(sprintf(
"select login_name from employees where id=%d",
$_POST['id'])));
if ($res !== false) {
$old = $res['login_name'];
} else {
// handle the error, including checking mysql_error()
}

Cheers
