PHP development to build an enterprise resource planning (ERP) system with customer order management function

The enterprise resource planning (ERP) system is a very important system in current enterprise management. It can help Enterprises manage and master every aspect to improve work efficiency and management level. Among them, the customer order management function is an extremely important part of enterprise operations. Reasonable and orderly management of customer orders can help enterprises improve production efficiency, optimize supply chains, and improve customer satisfaction.

In this article, we will use PHP to develop a simple enterprise resource planning (ERP) system for customer order management functions.

First of all, set up a development environment in the PHP environment to ensure that you have the basic ability to use PHP for development. Next, we will use PHP to write the following functional modules:

Login module
The login module is the entrance to the ERP system. Only authenticated users can use other functions of the system. The following is a sample code for a simple login function:

<?php
session_start();

function login($username, $password) {
    // 根据用户名和密码进行验证，检查数据库中的用户信息
    $sql = "SELECT * FROM users WHERE username = '$username' AND password = '$password'";
    $result = mysqli_query($conn, $sql);
    
    if(mysqli_num_rows($result) == 1) { // 认证成功
        $_SESSION['username'] = $username;
        $_SESSION['loggedin'] = true;
        header("Location: dashboard.php"); // 跳转到主页
    } else {
       echo "登录失败，请检查用户名和密码。";
    }
}
?>

<html>
<body>
    <form action="login.php" method="POST">
        <input type="text" name="username" placeholder="用户名"><br>
        <input type="password" name="password" placeholder="密码"><br>
        <input type="submit" value="登录">
    </form>
</body>
</html>

Customer order management module
The customer order management module mainly includes functions such as browsing orders, adding orders, deleting orders, and editing orders. . The following is a sample code for a simple order management function:

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "username", "password", "database_name");

// 浏览订单
function browseOrders() {
    $sql = "SELECT * FROM orders";
    $result = mysqli_query($conn, $sql);
    
    while($row = mysqli_fetch_assoc($result)) {
        echo "订单号：" . $row['order_id'] . "<br>";
        echo "客户名称：" . $row['customer_name'] . "<br>";
        // 其他订单信息...
        echo "<br>";
    }
}

// 添加订单
function addOrder($customerName, $orderDate, $totalAmount) {
    $sql = "INSERT INTO orders (customer_name, order_date, total_amount) VALUES ('$customerName', '$orderDate', '$totalAmount')";
    if(mysqli_query($conn, $sql)) {
        echo "订单添加成功。";
    } else {
        echo "添加订单失败，请重试。";
    }
}

// 删除订单
function deleteOrder($orderId) {
    $sql = "DELETE FROM orders WHERE order_id = '$orderId'";
    if(mysqli_query($conn, $sql)) {
        echo "订单删除成功。";
    } else {
        echo "删除订单失败，请重试。";
    }
}

// 编辑订单
function editOrder($orderId, $customerName, $orderDate, $totalAmount) {
    $sql = "UPDATE orders SET customer_name = '$customerName', order_date = '$orderDate', total_amount = '$totalAmount' WHERE order_id = '$orderId'";
    if(mysqli_query($conn, $sql)) {
        echo "订单编辑成功。";
    } else {
        echo "编辑订单失败，请重试。";
    }
}
?>

Through the above code, we can implement an ERP system with a simple customer order management function. This system can help companies manage orders, improve production efficiency and customer satisfaction.

Of course, the above code is just a simple example. In the actual development process, we need to carry out more function expansion and data processing. At the same time, in order to ensure the security and stability of the system, we also need to reasonably design and maintain the database, as well as perform data verification and permission control.

To sum up, by using PHP to develop the customer order management function of the enterprise resource planning (ERP) system, it can help enterprises improve operational efficiency and management level, realize the automation and standardization of order management, thereby enhancing enterprise competition. power and economic benefits.
