Thoughts on the design of mall product SKU management system developed with PHP

Thinking about the design of the mall product SKU management system developed with PHP

Introduction:
In the field of e-commerce, the product SKU management system is very important for merchants. Products can be accurately described and classified through SKU (Stock Keeping Unit), which facilitates merchants to manage inventory, inventory forecasting, price management, etc. This article will introduce how to use PHP to develop a simple mall product SKU management system and give code examples.

1. Demand analysis

1. Commodity SKU attribute management: Products can have multiple attributes, such as color, size, etc., and a powerful attribute management module needs to be designed.
2. Commodity SKU inventory management: Ability to increase and decrease the inventory of product SKUs, and query the real-time inventory of each SKU.
3. Commodity SKU price management: can adjust the price of product SKU, and can query the real-time price of each SKU.
4. Commodity SKU sales statistics: It can count the sales of each SKU, including sales quantity and sales volume, etc.

2. System design

1. Database design
   According to the above requirements, we need to design the following database tables:
2. Product table (product ): Stores the basic information of the product, such as product name, description, etc.
3. SKU table (sku): stores the basic information of product SKU, such as SKU name, inventory, price, etc.
4. SKU attribute table (sku_attribute): stores attribute information of product SKU, such as color, size, etc.
5. SKU attribute value table (sku_attribute_value): stores the value of the SKU attribute, such as red, XL, etc.
6. SKU attribute association table (sku_attribute_relation): associates the attribute information of SKU and products.
7. Page design
   Based on the needs, we need to design the following pages:
8. Product list page: display the basic information of all products, including names, descriptions, etc.
9. SKU management page: Displays the SKU list of products, including SKU name, inventory, price, etc., and provides operations such as adding, editing, and deleting.
10. Attribute management page: displays the attribute list of the product, including attribute names and attribute values, and provides operations such as adding, editing, and deleting.

3. Code Implementation
The following is a code example for using PHP to implement a product SKU management system:

1. Code for querying product list:

   <?php
   // 查询商品列表
   $sql = "SELECT * FROM product";
   $result = mysqli_query($conn, $sql);
   
   // 输出商品列表
   while($row = mysqli_fetch_assoc($result)) {
    echo "商品名称：" . $row['name'] . "<br>";
    echo "商品描述：" . $row['description'] . "<br>";
    echo "<br>";
   }
   
   // 关闭数据库连接
   mysqli_close($conn);
   ?>

2. Query SKU list code:

   <?php
   // 查询SKU列表
   $sql = "SELECT * FROM sku";
   $result = mysqli_query($conn, $sql);
   
   // 输出SKU列表
   while($row = mysqli_fetch_assoc($result)) {
    echo "SKU名称：" . $row['name'] . "<br>";
    echo "库存：" . $row['stock'] . "<br>";
    echo "价格：" . $row['price'] . "<br>";
    echo "<br>";
   }
   
   // 关闭数据库连接
   mysqli_close($conn);
   ?>

3. Add SKU code:

   <?php
   // 获取表单数据
   $name = $_POST['name'];
   $stock = $_POST['stock'];
   $price = $_POST['price'];
   
   // 增加SKU
   $sql = "INSERT INTO sku (name, stock, price) VALUES ('$name', '$stock', '$price')";
   $result = mysqli_query($conn, $sql);
   
   if ($result) {
    echo "SKU添加成功！";
   } else {
    echo "SKU添加失败！";
   }
   
   // 关闭数据库连接
   mysqli_close($conn);
   ?>

4. Summary
This article introduces the design thinking of using PHP developer mall product SKU management system, and gives relevant code examples. Through reasonable demand analysis, system design and code implementation, a powerful mall product SKU management system can be developed to improve merchants' operational efficiency and user experience.

(Note: The above code examples are only for demonstration, and factors such as security and performance optimization need to be considered in actual development.)
