Application of the sales order tracking module developed by PHP in the enterprise resource planning (ERP) system

With the development of information technology, the enterprise resource planning (ERP) system has become an important tool for modern enterprise management. Among them, sales order tracking is a key module in the ERP system, which can help enterprises monitor and grasp the order status during the sales process, and provide enterprises with timely and accurate sales data analysis. This article will introduce how to use PHP to develop a sales order tracking module, and illustrate it with code examples.

1. Implement demand analysis of the sales order tracking module
   The sales order tracking module mainly includes the following functions:
2. Record the basic information of the sales order, such as order number, customer information, etc.;
3. Track order status changes, such as order creation, pending, shipped, etc.;
4. Provide query and analysis functions for sales orders, such as filtering orders by customer, time range, etc.;
5. Provide statistical chart display functions, such as statistical charts of sales amount and order quantity.
6. Database Design
   In the MySQL database, we can define a table named "sales_orders" to store sales order information. The table structure is as follows:

CREATE TABLE sales_orders (
id INT(11) AUTO_INCREMENT PRIMARY KEY,
order_number VARCHAR(20) NOT NULL,
customer_id INT(11) NOT NULL ,
status ENUM('Created', 'Processing', 'Shipped', 'Delivered') NOT NULL,
order_date TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);

where, "order_number The "field is used to store the order number, the "customer_id" field is used to associate customer information, the "status" field is used to record the order status, and the "order_date" field is used to record the creation time of the order.

3. Develop sales order tracking module using PHP
   First, we need to create a PHP file named "sales_order_tracking.php" to handle the tracking function of sales orders. The following is a code example:

<?php
// 连接数据库
$mysqli = new mysqli("localhost", "username", "password", "database");

// 检查连接是否成功
if ($mysqli->connect_error) {
    die("数据库连接失败： " . $mysqli->connect_error);
}

// 查询销售订单
$sql = "SELECT * FROM sales_orders";
$result = $mysqli->query($sql);

// 输出销售订单
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "订单号：" . $row["order_number"] . "<br>";
        echo "客户ID：" . $row["customer_id"] . "<br>";
        echo "订单状态：" . $row["status"] . "<br>";
        echo "订单日期：" . $row["order_date"] . "<br><br>";
    }
} else {
    echo "没有找到销售订单。";
}

// 关闭数据库连接
$mysqli->close();
?>

The above code first connects to the MySQL database, then queries the sales order table, and outputs the basic information of the order through loop traversal. Finally close the database connection.

4. Sales order query and analysis function
   In order to implement the query and analysis function of sales orders, we can add the following code in the "sales_order_tracking.php" file:

<?php
// ...

// 根据客户ID查询订单
$customer_id = 1;
$sql = "SELECT * FROM sales_orders WHERE customer_id = " . $customer_id;
$result = $mysqli->query($sql);

// 输出查询结果
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "订单号：" . $row["order_number"] . "<br>";
        echo "客户ID：" . $row["customer_id"] . "<br>";
        echo "订单状态：" . $row["status"] . "<br>";
        echo "订单日期：" . $row["order_date"] . "<br><br>";
    }
} else {
    echo "没有找到相关的销售订单。";
}

// ...

// 查询销售订单的统计数据
$sql = "SELECT COUNT(*) as total_orders, SUM(order_amount) as total_amount FROM sales_orders";
$result = $mysqli->query($sql);

// 输出统计结果
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "总订单数量：" . $row["total_orders"] . "<br>";
        echo "总销售金额：" . $row["total_amount"] . "<br>";
    }
} else {
    echo "没有找到销售订单。";
}

// ...
?>

In the above code, we add query statements to implement the function of querying orders and querying order statistics based on customer IDs. According to specific needs, more query conditions and statistical indicators can be added.

Through the above code example, we can see the application of the sales order tracking module developed using PHP in the enterprise resource planning (ERP) system. It can help enterprises grasp the status information of sales orders in real time, provide more comprehensive and accurate sales analysis reports, and provide strong support for enterprise decision-making.
