almost perfect - I would not pass the referer this way, though. creates
overhead
and then I don't think the else case inside the post() is necessary.
after a post the same post data will populate the inputs anyway. therefore
the Model.referer input should still have the same value.
no need to resend this variable to the view.
I also dont like to unnecessarily set defaults in the view.
echo $this->Form->input('Model.referer');
public function add() {
if ($this->request->is('post')) {
// validate ...
if ($this->Model->save()) {
$referer =
!empty($this->request->data['Model']['referer'])
? $this->request->data['Model']['referer']
: '/'; // or some other fallback route of
your choice
$this->redirect($referer);
}
} else {
$this->request->data['Model']['referer'] = $this->referer();
}
}
you agree?
