Code generation for the order tracking function in the PHP inventory management system
Note: This article takes a simple inventory management system as an example to show how to use PHP code to implement the order tracking function.
Order tracking is one of the very important functions in the inventory management system. It can help us track the status of orders and update inventory in a timely manner. The following is a code example of an order tracking function based on PHP:
CREATE TABLE `orders` ( `id` int(11) NOT NULL AUTO_INCREMENT, `order_number` varchar(50) NOT NULL, `status` enum('pending','processing','shipped','delivered','cancelled') NOT NULL, `created_at` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
class OrderTracking { private $db; public function __construct($db) { $this->db = $db; } // 创建新订单 public function createOrder($orderNumber) { $status = 'pending'; $createdAt = date('Y-m-d H:i:s', time()); $sql = "INSERT INTO orders (order_number, status, created_at) VALUES ('$orderNumber', '$status', '$createdAt')"; $this->db->query($sql); return $this->db->insert_id; } // 更新订单状态 public function updateOrderStatus($orderId, $status) { $sql = "UPDATE orders SET status = '$status' WHERE id = $orderId"; $this->db->query($sql); } // 获取订单状态 public function getOrderStatus($orderId) { $sql = "SELECT status FROM orders WHERE id = $orderId"; $result = $this->db->query($sql); $row = $result->fetch_assoc(); return $row['status']; } }
In the above code, we created an "OrderTracking" class, which contains three methods:
// 假设我们已经建立了数据库连接对象$db $orderTracking = new OrderTracking($db); // 创建新订单 $orderNumber = 'ORD-20210101-001'; $orderId = $orderTracking->createOrder($orderNumber); // 更新订单状态 $orderTracking->updateOrderStatus($orderId, 'processing'); // 获取订单状态 $status = $orderTracking->getOrderStatus($orderId); echo '订单状态:' . $status;
In the above sample code, we first create a new order and obtain the ID of the order. Then we update the order status to "processing". Finally, we use the "getOrderStatus" method to get the latest status of the order and output it.
Through the above code examples, we can see that it is very simple to use PHP to write the order tracking function in the inventory management system. By creating a class containing related methods and using database operation statements, we can easily implement functions such as order creation, status update, and status acquisition. This will greatly improve the efficiency and accuracy of your inventory management system.
