Re: return Json values cakephp 1.3.8

This:

$this->set('provinces', $this->City->Province->find('list',
array('conditions' =>
array('province.country_id' =>
$this->params['url']['countryId']),
'recursive' => -1)));
echo json_encode($provinces);
}

Should be:

echo json_encode($this->City->Province->find('list',
array('conditions' => array('province.country_id' => $this-
>params['url']['countryId']),'recursive' => -1)));
