Second-hand recycling website developed with PHP optimizes logistics information tracking function

The second-hand recycling website developed by PHP optimizes the logistics information tracking function

As people pay more and more attention to environmental protection and resource recycling, second-hand recycling websites have become a popular development area. For this type of website, the logistics information tracking function is very important, because it can help administrators and users understand the transportation status of goods and grasp the location and status of goods in real time. In this article, we will take a second-hand recycling website developed in PHP as an example to introduce how to optimize the logistics information tracking function.

1. Demand analysis

Before implementing the logistics information tracking function, we first need to clarify our needs. Generally speaking, a basic logistics information tracking function should include the following aspects:

1. Generate a unique logistics tracking number when the product leaves the warehouse and bind it to the product.
2. The logistics company enters or updates the transportation information of the goods based on the logistics tracking number, such as transportation status, location, etc.
3. Users can check the transportation status and location of goods based on the logistics tracking number.

2. Database design

Before implementing the logistics information tracking function, we need to design a database to store relevant data. Assuming that our database name is "recycling_website", we can create two tables to store related data: the goods table and the logistics table.

1. goods table:

CREATE TABLE `goods` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `logistics_tracking_number` varchar(30) DEFAULT NULL,
  `shipping_status` tinyint(1) DEFAULT NULL,
  `shipping_location` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

2. logistics table:

CREATE TABLE `logistics` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `goods_id` int(11) NOT NULL,
  `status` tinyint(1) DEFAULT NULL,
  `location` varchar(255) DEFAULT NULL,
  `timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  KEY `fk_goods_id` (`goods_id`),
  CONSTRAINT `fk_goods_id` FOREIGN KEY (`goods_id`) REFERENCES `goods` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

3. Implement functions

1. A unique logistics tracking number is generated when the product leaves the warehouse and is bound to the product.

When the goods leave the warehouse, we can use the following code to generate a unique logistics tracking number and bind it to the goods:

function generateTrackingNumber() {
  // 生成一个唯一的物流追踪号，这里我们使用时间戳和随机数相结合
  $trackingNumber = time() . mt_rand(100, 999);
  
  // 将生成的物流追踪号与商品绑定
  $goodsID = $_POST['goods_id']; // 假设表单中有一个名为goods_id的字段
  
  // 将物流追踪号存入数据库
  $sql = "UPDATE goods SET logistics_tracking_number = '{$trackingNumber}' WHERE id = '{$goodsID}'";
  // 执行SQL语句
  // ...
}

2. The logistics company will follow the logistics Enter or update the shipping information of the product with the tracking number.

Logistics companies can enter or update the transportation information of goods through the following code:

function updateShippingStatus() {
  $trackingNumber = $_POST['tracking_number']; // 假设表单中有一个名为tracking_number的字段
  $status = $_POST['status']; // 假设表单中有一个名为status的字段
  $location = $_POST['location']; // 假设表单中有一个名为location的字段
  
  // 根据物流追踪号查询商品ID
  $sql = "SELECT id FROM goods WHERE logistics_tracking_number = '{$trackingNumber}'";
  // 执行SQL语句，并获取查询结果
  // ...
  
  // 将商品的运输信息存入数据库
  $sql = "INSERT INTO logistics (goods_id, status, location) VALUES ('{$goodsID}', '{$status}', '{$location}')";
  // 执行SQL语句
  // ...
}

3. Users can query the transportation status and location of goods based on the logistics tracking number.

Users can query the transportation status and location of goods through the following code:

function getShippingStatus() {
  $trackingNumber = $_POST['tracking_number']; // 假设表单中有一个名为tracking_number的字段
  
  // 根据物流追踪号查询商品的运输状态和位置
  $sql = "SELECT status, location FROM logistics WHERE goods_id IN (SELECT id FROM goods WHERE logistics_tracking_number = '{$trackingNumber}')";
  // 执行SQL语句，并获取查询结果
  // ...
}

4. Summary

Through the above code example, we can implement a simple Logistics information tracking function. Of course, based on specific business needs, we can further optimize the code, such as adding query history, sending transportation status update notifications, and other functions. I believe that through the introduction of this article, readers can have a certain understanding and ideas on how to optimize the logistics information tracking function. I wish you all good results in developing your second-hand recycling website!
