按区域获取总订单

Question

在管理面板opencart上有世界地图，并按国家显示总订单。我可以按国家更改地图，并且需要按区域获得总订单，但是按国家/地区可以获得订单。如何改变？

public function getTotalOrdersByCountry() { 
 
\t \t $query = $this->db->query("SELECT COUNT(*) AS total, SUM(o.total) AS amount, c.iso_code_2 FROM `" . DB_PREFIX . "order` o LEFT JOIN `" . DB_PREFIX . "country` c ON (o.payment_country_id = c.country_id) WHERE o.order_status_id > '0' GROUP BY o.payment_country_id"); 
 

 
\t \t return $query->rows; 
 
\t }

它的代码从控制器

$query = $this->db->query("SELECT COUNT(*) AS total, SUM(o.total) AS amount, z.code as iso_code_2 
          FROM `" . DB_PREFIX . "order` o 
          LEFT JOIN `" . DB_PREFIX . "zone` z ON (o.payment_zone_id = z.zone_id) 
          WHERE o.order_status_id > '0' GROUP BY o.payment_zone_id");
