When you want to pass variables from the controller to the view, use
$this->set(). Otherwise, you're creating a variable that's outside the
view scope.
$this->set('user_id', $this->Session->read('userid'));
This will add the key & value to the $viewVars array. It'll be
available in the view because there's an extract() call in there
somewhere. In any case, it's all transparent. Use set() and then your
echo will work fine.
... unless there's no user_id in the session, of course ;-)
