Problemas no recebimento POST Checkout Cielo.

Boa noite a todos.

Resolvendo problemas, e vindo com mais problemas rs.

Fiz a integração com a Cielo, porém agora estou com problemas no recebimento dos dados do pedido via POST que eles mandam na página de Notificação e Mudança de Status.

Estou usando o framework CodeIgniter.

Recebo E-mail deles com os seguintes dados.

Meu Route.php

$route['store/notify'] = 'cart/notify/';
$route['store/status'] = 'cart/status/';

E no controller Cart.php

	public function notify(){
 $order_number = $this->input->post('order_number');

 if(isset($order_number)){
 $mod_ship = $this->input->post('shipping_type');
 $name_ship = $this->input->post('shipping_name');
 $price_ship = $this->input->post('shipping_price');
 $cep_ship = $this->input->post('shipping_adress_zipcode');
 $dist_ship = $this->input->post('shipping_adress_district');
 $city_ship = $this->input->post('shipping_adress_city');
 $state_ship = $this->input->post('shipping_state');
 $adre_ship1 = $this->input->post('shipping_adress_line1');
 $adre_ship2 = $this->input->post('shipping_adress_line2');
 $number_ship = $this->input->post('shipping_adress_number');
 $details_ship = $mod_ship.'<br>'.
 $name_ship.'<br>'.
 $price_ship.'<br>'.
 $cep_ship.'<br>'.
 $state_ship.'<br>'.
 $city_ship.'<br>'.
 $adre_ship1.', '.$number_ship.', '.$adre_ship2.', '.$dist_ship;
 $valor_total_cf = $valor_total + $price_ship;

 $data = array(
 'details_ship' => $details_ship,
 'order_price' => $valor_total_cf,
 'order_shipping' => $price_ship,
 'order_status' => $this->input->post('payment_status'),
 'order_tid'	=> $this->input->post('tid')
 );

 $myOrder = $this->store_model->upMyOrders($order_number, $data);

 echo '<status>OK</status>';

 $this->load->view('store/notify');
 } else {
 redirect(base_url());
 }

	}
	public function status(){
 $order_number = $this->input->post('order_number');
 $data = array(
 'order_status' => $this->input->post('payment_status'),
 );

 $myOrder = $this->store_model->upMyOrders($order_number, $data);
 echo '<status>OK</status>';
 $this->load->view('store/status');
	}

E o Store_model.php

 public function upMyOrders($order_number, $data){
 $query = $this->db->where(array('order_number' => $order_number))
 ->update('tb_store_orders', $data);
 return true;
 }

Tem algo de errado? Alguém pra dar uma luz?
