You have forgotten to quote the id inside the $_POST, i.e. $_POST["id"]
But why a $_POST inside a $_SESSION? Could it be either:

$sql = "UPDATE attendance SET logouttime = NOW() WHERE id = '".$_SESSION["id"]."'";

or

$sql = "UPDATE attendance SET logouttime = NOW() WHERE id = '".$_POST["id"]."'";

However, you should consider the following:
1. Switching to mysqli extension[^] as the ext/mysql extension has been deprecated [^]since PHP 5.5.
2. Use prepared statement[^] for the sql
