Use PHP to develop the mall logistics interface: code to control the goods delivery process!

With the development of the e-commerce industry, more and more people choose to purchase goods online, which brings huge development opportunities to the logistics industry. As a developer, we need to provide an efficient and reliable logistics interface for shopping malls to realize the scheduling and control of the goods out-of-warehouse process.

In this article, we will use PHP language to develop a simple logistics interface to control the outbound process of goods. First, we need to build a database to store product information and order information. We use the MySQL database and create two tables, one for the products and one for the orders. The product table contains the following fields: product ID, product name, and product inventory quantity; the order table contains the following fields: order ID, product ID, order quantity, and order status.

Next, we started writing PHP code to control the product delivery process. First, we need to connect to the database, and we can use PHP's mysqli extension library to achieve the connection. Then, we can obtain product information and order information through SQL query statements for subsequent process control.

In order to simplify the code, we can use an object-oriented approach to development. We can create a class called Logistics, which contains some methods to handle the goods outbound process. First, we can get the inventory quantity of the product through the product ID, and then judge whether it can be shipped out based on the order status in the order form. If it can be shipped out of the warehouse, the order status is modified to shipped out, and the corresponding inventory quantity is updated. If it cannot be shipped out of the warehouse, the user information will be prompted.

The following is a simple sample code:

<?php

// 连接数据库
$mysqli = new mysqli("localhost", "username", "password", "database");
if ($mysqli->connect_error) {
    die("数据库连接失败: " . $mysqli->connect_error);
}

// 商品出库流程控制类
class Logistics {
    
    private $mysqli;
    
    // 构造函数
    public function __construct($mysqli) {
        $this->mysqli = $mysqli;
    }
    
    // 商品出库
    public function goodsOutbound($orderID) {
        $sql = "SELECT * FROM orders WHERE orderID = '$orderID'";
        $result = $this->mysqli->query($sql);
        
        if ($result->num_rows > 0) {
            $row = $result->fetch_assoc();
            $status = $row["status"];
            
            if ($status == "未出库") {
                $goodsID = $row["goodsID"];
                $quantity = $row["quantity"];
                
                $sql = "SELECT * FROM goods WHERE goodsID = '$goodsID'";
                $result = $this->mysqli->query($sql);
                $row = $result->fetch_assoc();
                $stock = $row["stock"];
                
                if ($stock >= $quantity) {
                    $stock -= $quantity;
                    
                    $sql = "UPDATE goods SET stock = '$stock' WHERE goodsID = '$goodsID'";
                    $this->mysqli->query($sql);
                    
                    $sql = "UPDATE orders SET status = '已出库' WHERE orderID = '$orderID'";
                    $this->mysqli->query($sql);
                    
                    echo "商品出库成功！";
                } else {
                    echo "商品库存不足，无法出库！";
                }
            } else {
                echo "订单已经出库！";
            }
        } else {
            echo "订单不存在！";
        }
    }
}

// 实例化物流类
$logistics = new Logistics($mysqli);

// 商品出库
$logistics->goodsOutbound("1001");

// 关闭数据库连接
$mysqli->close();

?>

Through the above sample code, we can implement a simple product delivery process control system. When the user calls the goodsOutbound method, we can determine whether it can be shipped out based on the incoming order ID and handle it accordingly.

To sum up, using PHP to develop a shopping mall logistics interface can help merchants control and manage the goods out-of-warehouse process. We need to build a database, create the required tables, and use PHP code to connect to the database and manipulate the data. Through object-oriented development, we can encapsulate and reuse code more easily. Hope this article can be helpful to you!
