Re: How to redirect two pages back?

On first display of the form pass the referer to the view to add it to the form.

echo $this->Form->input('Model.referer', array('value' => $referer));

public function add() {

if ($this->request->is('post')) {

$referer = isset($this->request->data['Model']['referer'])
? $this->request->data['Model']['referer']
: '/'; // or some other fallback route of your choice

// validate ...

if ($this->Model->save()) {

$this->redirect($referer);
}
else {
// flash msg, log, etc.
$this->set(compact('referer'));
}
}
else {
$this->set('referer', $this->referer());
}
}

You have to use the else block to set the view var because if the save
failed it would overwrite it to the empty form. Likewise, you need to
create the $referer method var before attempting to save so that it's
available either way (to redirect or reset the view var).
