Multiple row inserts on db query

[eluser]superfake123[/eluser]
sorry I thought that part was obvious?

Code:

$limit = count($Product);
for($i=0;$i<$limit;$i++)
{
  $data = array(
    'sale_id'           => $sale_id[$i],
    'customer_address'  => $customer_address[$i],
    'customer_borough'  => $customer_borough[$i],
    'delivered'         => $delivered[$i],
    'customer_id'       => $customer_id[$i],
    'driver_id'         => $driver_id[$i],
    'order_cost'        => $order_cost[$i]
  );
  $this->db->insert('delivery_sales', $data);
}
