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?

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).
