Hi,

You'd pass the event_id to the controller action by including it inn
the url:

$html->link('Register', array('controller'=>'events',
'action'=>'register', $row['Event']['id']), array('title'=>'Register
for '.$row['Event']['title']));

The above link would expect to find an action in the Event controller
starting like:

function register($event_id) {
  echo $event_id // just to show the event's id has been passed.
}

And you'd access the session data from within the controller action by
using

$this->Session->read('id')

Not sure about this one to be honest tough, as ever accessed the
sessions id myself.
