Detailed explanation of the mall order status conversion process developed by PHP

In the process of e-commerce development, order management is a very important and complex part. Orders in the mall need to go through multiple status transitions, such as pending payment, paid, shipped, completed, etc. This article will introduce in detail the process of mall order status conversion in PHP development and provide code examples.

1. Design of order status

Before starting development, you first need to design the order status. Order status usually includes the following:

1. Pending payment: The payment has not been completed after the user places the order.
2. Payment: The user has completed the payment.
3. Delivered: The merchant has shipped the goods.
4. Completed: The user has confirmed receipt of the goods and the order transaction is completed.
5. Cancelled: In some cases, the user may cancel the order.

2. Database table structure design

In order to save the conversion record of order status, we need to design the corresponding database table.

order represents the main table of the order, including the basic information of the order, such as order number, user ID, order amount, etc.

The order_status table is used to save the conversion record of order status, including fields such as order ID, old status, new status, operator, and operation time.

The order status transfer table order_status is designed as follows:

CREATE TABLE `order_status` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` int(11) NOT NULL COMMENT '订单ID',
  `old_status` varchar(50) NOT NULL COMMENT '旧状态',
  `new_status` varchar(50) NOT NULL COMMENT '新状态',
  `operator` varchar(50) NOT NULL COMMENT '操作人',
  `operate_time` datetime NOT NULL COMMENT '操作时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='订单状态流转表';

3. Order status conversion process

Before implementing the order status conversion process, we first need to define the relationship between each status conversion rules. According to our design, the order status can be converted according to the following process:

Pending payment-> Paid-> Shipped-> Completed

At the same time, we need to process the order Cancel operation, convert the order status from Pending or Paid to Canceled.

The following is an example of PHP code for order status conversion:

// 1. 订单支付
function payOrder($order_id) {
   // 其他逻辑处理
   
   // 更新订单状态为已支付
   updateOrderStatus($order_id, "已支付");
}

// 2. 订单发货
function deliverOrder($order_id) {
    // 其他逻辑处理
    
    // 更新订单状态为已发货
    updateOrderStatus($order_id, "已发货");
}

// 3. 用户确认收货，订单完成
function confirmOrder($order_id) {
    // 其他逻辑处理
    
    // 更新订单状态为已完成
    updateOrderStatus($order_id, "已完成");
}

// 4. 取消订单
function cancelOrder($order_id) {
    // 其他逻辑处理
    
    // 更新订单状态为已取消
    updateOrderStatus($order_id, "已取消");
}

// 更新订单状态
function updateOrderStatus($order_id, $new_status) {
    // 其他逻辑处理
    
    // 获取旧状态
    $old_status = getOrderStatus($order_id);
    
    // 保存订单状态转换记录
    saveOrderStatusLog($order_id, $old_status, $new_status, "操作人", date("Y-m-d H:i:s"));
    
    // 更新order表的状态字段
    updateOrder($order_id, $new_status);
}

// 查询订单当前状态
function getOrderStatus($order_id) {
    // 查询数据库获取订单当前状态
    ...
}

// 记录订单状态转换记录
function saveOrderStatusLog($order_id, $old_status, $new_status, $operator, $operate_time) {
    // 将订单状态转换记录插入order_status表
    ...
}

// 更新order表的状态字段
function updateOrder($order_id, $new_status) {
    // 更新数据库order表的状态字段值
    ...
}
