Answer 1

$lastId = $this->User->id;
$location = explode(',',$this->request->data['User']['location']);
foreach($location as $value){
$data = array();
$data["name"] = $value;
$data["user_id"] = $lastId;
$this->Location->save($data,false);
$this->Location->id = false;
}

Model::saveAll(array $data = null, array $options = array())
$this->request->data['Location'] = explode(',',$this->request->data['User']['location']);
if ($this->User->saveAll($this->request->data, array('validate' => false))){ // ...}
