I guess what you have to do is to make an ajax call to your controller
that will check in the DB and render a view.
This view will update the "availabity" div.
You can make an ajaxlink (in a button form) and send the fields (user
etc) using the option 'with'. If you have a form for entering your
user name already there you can send the form (using it's Id) to the
controller check function.
In your controller you check if the name exists and set a message
using $this->set('message', 'ok');
your rendering view should look like this :
$ajax->div('Availability);
echo '<h2>'.$message.'</h2>';
$ajax->dviEnd('availability');
Hope this helps
