CakePHP - Multiple row edits - cakephp

Question

How can I do edits to a table on multiple rows?
I followed the tutorial here http://matsimitsu.com/blog/2008/01/06/saveall-with-cakephp.html but it doesn't seem to work.
Here is what I'm doing, but it's not working.
Thanks,
Tee
function editAll() {
$this->data = $this->Settings->find('all', array('conditions' => $conditions));
}
Then in the view, this is what I have
foreach ($this->data as $setting):
echo $form->input('Setting.' . $setting['Setting']["id"] . '.value', array('value' => $setting['Setting']["value"]));
endforeach;
Then in the add function I have
function add() {
if (!empty($this->data)) {
$this->Setting->create();
if ($this->Setting->saveAll($this->data)) {
$this->Session->setFlash(__('The Setting has been saved', true));
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The Setting could not be saved. Please, try again.', true));
}
}
}

You need to include the id field, so the data in your controller will look like this:
'Setting' => array(
0 => array(
'id' => 42,
'value' => 'foo'
),
1 => array(…)
)
So in the view, do this:
foreach ($this->data as $i => $setting) {
echo $this->Form->hidden("Setting.$i.id", array('value' => $setting['Setting']['id']));
echo $this->Form->input("Setting.$i.value", array('value' => $setting['Setting']['value']));
}
