PHP development to build an enterprise resource planning (ERP) system with sales order management functionality

PHP development of an enterprise resource planning (ERP) system that builds sales order management functions An important tool for your business. Among them, the sales order management function plays a vital role in business operations. This article will introduce how to use PHP to develop an enterprise resource planning (ERP) system with sales order management functions, and provide corresponding code examples.

1. Environment setup
First, we need to set up a PHP development environment locally. Here, we have chosen to use XAMPP as our local server environment. The specific steps are as follows:

Download and install XAMPP;

Start XAMPP;
1. Open the XAMPP control panel and start the Apache and MySQL services.
3. 2. Database design
Before developing the ERP system with sales order management function, we need to design the corresponding database first. In this example, we will need to create three tables: order, product, and customer.

Order table (order):
CREATE TABLE

order

(
idINT(11) NOT NULL AUTO_INCREMENT,
product_idINT(11) NOT NULL,
customer_idINT(11) NOT NULL,
quantityINT(11) NOT NULL,
total_priceDECIMAL(10, 2) NOT NULL,
PRIMARY KEY (id)
);Product table (product):
CREATE TABLE

product

(
idINT(11) NOT NULL AUTO_INCREMENT,
nameVARCHAR(50) NOT NULL,
priceDECIMAL(10, 2) NOT NULL,
PRIMARY KEY (id)
);Customer table (customer):
CREATE TABLE

customer

(
idINT(11) NOT NULL AUTO_INCREMENT,
nameVARCHAR(50) NOT NULL,
PRIMARY KEY (id)
);3. PHP development

Configuring the database connection

In PHP development, we need to configure the database connection to interact with the MySQL database . The following is an example database connection configuration code:

1. connect_error) { die("连接失败：" . $conn->connect_error); } ?>

Add order function

In the sales order management function, we need to provide the function of adding orders. The following is an example order addition code:

2. query($sql); $row = $result->fetch_assoc(); $price = $row['price']; // 计算订单总价 $total_price = $price * $quantity; // 插入订单到数据库 $sql = "INSERT INTO `order` (product_id, customer_id, quantity, total_price) VALUES ($product_id, $customer_id, $quantity, $total_price)"; if ($conn->query($sql) === TRUE) { echo "订单添加成功"; } else { echo "发生错误：" . $conn->error; } // 关闭数据库连接 $conn->close(); ?>

   Copy after login
   
   
Query order function

In the sales order management function, we also need to provide the function of querying orders. The following is an example order query code:

3. query($sql); // 输出查询结果 if ($result->num_rows > 0) { while ($row = $result->fetch_assoc()) { echo "订单号：" . $row['order_id'] . "
   "; echo "产品名：" . $row['product_name'] . "
   "; echo "客户名：" . $row['customer_name'] . "
   "; echo "数量：" . $row['quantity'] . "
   "; echo "总价：" . $row['total_price'] . "
   "; echo "
   "; } } else { echo "没有订单记录"; } // 关闭数据库连接 $conn->close(); ?>

   Copy after login
   
   IV. Summary
By using PHP to develop an enterprise resource planning (ERP) system with sales order management functions, we can add and query orders. Function. The above is a simple example, you can further improve and expand the system according to actual needs. I hope this article will be helpful to you in the development of enterprise resource planning (ERP) system for sales order management functions.
