How to use PHP to write a mall SKU management system

In the modern e-commerce era, merchants are faced with the management of a large number of products and different specifications, and the SKU management system has become indispensable. The missing link. SKU (Stock Keeping Unit) is an important way for merchants to manage product inventory and specifications. For a mall, a good SKU management system can improve inventory efficiency, reduce error rates, and improve user experience. This article will introduce how to use PHP to write a mall SKU management system to help merchants better manage product information.

1. Database design and table structure

The core of the mall SKU management system is the database, which stores and manages product information through a reasonable table structure. In the database, we need to create at least two tables: product information table and SKU specification table.

The product information table is used to store basic information about the product, such as product ID, product name, price, description, etc. The SKU specification table is used to store different specification information of the product, such as specification ID, specification name, inventory, etc.

You can use the following SQL statements to create product information tables and SKU specification tables:

CREATE TABLE `product` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(100) NOT NULL,
  `price` DECIMAL(10, 2) NOT NULL,
  `description` TEXT NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `sku` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `product_id` INT(10) UNSIGNED NOT NULL,
  `spec_name` VARCHAR(50) NOT NULL,
  `stock` INT(10) UNSIGNED NOT NULL,
  PRIMARY KEY (`id`),
  INDEX `product_id` (`product_id`),
  CONSTRAINT `fk_product_id` FOREIGN KEY (`product_id`) REFERENCES `product` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. Front-end interface design

Front-end interface of the mall SKU management system It needs to be convenient for merchants to enter and manage product information and SKU specifications.

You can use HTML, CSS and JavaScript to design the front-end interface, and add add, edit and delete buttons to the product information and SKU specification tables so that merchants can operate on product information and SKU specifications. At the same time, specifications can be dynamically added or deleted, and corresponding SKUs are automatically generated based on the selected specifications.

3. Controller and model writing

Write controllers and models through PHP to interact with the database. The controller is responsible for accepting user requests and parameters, calling the model to perform corresponding database operations, and finally interacting with the front-end interface for data. The model is responsible for adding, deleting, modifying and querying the database.

In the controller, you can write the following methods to implement addition, deletion, modification and query of product information and SKU specifications:

// 获取商品信息
function getProduct($id) {
  // SQL查询语句
  $sql = "SELECT * FROM product WHERE id = $id";
  // 执行查询操作
  // ...
  // 返回结果
  return $result;
}

// 添加商品
function addProduct($name, $price, $description) {
  // SQL插入语句
  $sql = "INSERT INTO product (name, price, description) VALUES ($name, $price, $description)";
  // 执行插入操作
  // ...
  // 返回结果
  return $result;
}

// 编辑商品
function updateProduct($id, $name, $price, $description) {
  // SQL更新语句
  $sql = "UPDATE product SET name = $name, price = $price, description = $description WHERE id = $id";
  // 执行更新操作
  // ...
  // 返回结果
  return $result;
}

// 删除商品
function deleteProduct($id) {
  // SQL删除语句
  $sql = "DELETE FROM product WHERE id = $id";
  // 执行删除操作
  // ...
  // 返回结果
  return $result;
}

// 获取SKU规格
function getSKU($product_id) {
  // SQL查询语句
  $sql = "SELECT * FROM sku WHERE product_id = $product_id";
  // 执行查询操作
  // ...
  // 返回结果
  return $result;
}

// 添加SKU规格
function addSKU($product_id, $spec_name, $stock) {
  // SQL插入语句
  $sql = "INSERT INTO sku (product_id, spec_name, stock) VALUES ($product_id, $spec_name, $stock)";
  // 执行插入操作
  // ...
  // 返回结果
  return $result;
}

// 编辑SKU规格
function updateSKU($id, $spec_name, $stock) {
  // SQL更新语句
  $sql = "UPDATE sku SET spec_name = $spec_name, stock = $stock WHERE id = $id";
  // 执行更新操作
  // ...
  // 返回结果
  return $result;
}

// 删除SKU规格
function deleteSKU($id) {
  // SQL删除语句
  $sql = "DELETE FROM sku WHERE id = $id";
  // 执行删除操作
  // ...
  // 返回结果
  return $result;
}

4. Back-end logic processing

Call methods in the controller through the front-end interface to interact with the back-end logic. The corresponding method is called according to the user's operation, and corresponding prompts and displays are performed on the front-end interface based on the returned results.

For example, when a merchant clicks the add product button, the addProduct method is called based on the product information entered by the user, the data is inserted into the database, and the corresponding results are returned. In the front-end interface, a prompt of "Add successfully" or "Add failed" is displayed based on the return result.

5. Project deployment and testing

After development is completed, deploy the project to the server and perform testing. During the testing process, different user operations and data inputs can be simulated to test whether the mall SKU management system operates normally under various circumstances.
