ORM/Extra Validate iby two field - validation

Question

Kohana 3.2
I want to check my parent_id but i need the second value of type_id.
Code:
public function rules()
{
return array(
'type_id' => array(
array('not_empty'),
array('digit'),
),
'parent_id' => array(
array('digit'),
array(array($this,'check_category'),array(':value', ':field','type_id'))
),
);
}
public function check_category($parent_id,$field,$type_id)
{
die($type_id);
}
How to sent two values of my field to my function ??
After i make that in my controller :
if(isset($_POST['submit']))
{
$data = Arr::extract($_POST, array('type_id', 'parent_id', 'name', 'comment'));
$category = ORM::factory('kindle_category');
$category->values($data);
try {
$extra_rules = Validation::factory($_POST)
->rule('parent_id','Kindle::check_category',array($data['type_id'],$data['parent_id'],'parent_id',':validation'));
$category->save($extra_rules);
$this->request->redirect('kindle/category');
}
catch (ORM_Validation_Exception $e) {
$errors = $e->errors('validation');
}
}
if($parent->type_id!=$type_id)
{
$validation->error($field, 'Dog name, not cat!');
return false;
}
How to see my error "Dog name,not cat!' in my View ?
