PHP Programming Guide: Methods for Implementing Product Multi-Specification SKU

1. Background Introduction

In the field of e-commerce, product multi-specification (Specification ) means that the same product can have different specification options, such as color, size, capacity, etc. SKU (Stock Keeping Unit) refers to the unique identification code of different specifications. SKU can uniquely identify the different specifications of the product.

The method of realizing multiple product specifications SKU is a common requirement in e-commerce system development. This article will introduce a method based on PHP programming to realize the function of multi-specification SKU of products.

2. Data design

First of all, it is necessary to design the database structure to store product, specification and SKU information. Three tables can be designed: products, specifications and skus.

(1)products table: used to store basic information of products, including product name, description, etc.

CREATE TABLE products (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL,
  description TEXT
);

(2)specificationsTable: used to store specification information, including specification name and specification options.

CREATE TABLE specifications (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL
);

CREATE TABLE specification_options (
  id INT PRIMARY KEY AUTO_INCREMENT,
  specification_id INT,
  option_name VARCHAR(255) NOT NULL,
  FOREIGN KEY (specification_id) REFERENCES specifications(id)
);

(3) skus Table: used to store SKU information, including inventory, price, etc.

CREATE TABLE skus (
  id INT PRIMARY KEY AUTO_INCREMENT,
  product_id INT,
  sku_code VARCHAR(255) NOT NULL,
  specification_values TEXT,
  price DECIMAL(10, 2),
  stock INT,
  FOREIGN KEY (product_id) REFERENCES products(id)
);

3. Implementation logic

When realizing the function of product multi-specification SKU, the following core steps are required:

(1) Create products: According to needs, create products and save them to the products table.

$name = $_POST['name'];
$description = $_POST['description'];

$sql = "INSERT INTO products (name, description) VALUES ('$name', '$description')";
// 执行插入操作

$product_id = mysqli_insert_id($conn);  // 获取插入的商品ID

(2) Create specifications and specification options: Create specifications and corresponding specification options according to requirements, and save them to the specifications table and specification_options table.

$specifications = $_POST['specifications'];

foreach ($specifications as $i => $specification) {
  $specification_name = $specification['name'];
  $option_names = $specification['options'];

  $sql = "INSERT INTO specifications (name) VALUES ('$specification_name')";
  // 执行插入操作
  $specification_id = mysqli_insert_id($conn);

  foreach ($option_names as $option_name) {
    $sql = "INSERT INTO specification_options (specification_id, option_name) VALUES ('$specification_id', '$option_name')";
    // 执行插入操作
  }
}

(3) Create SKU: Based on the combination of specifications, create SKU and save it to the skus table.

$specification_values = $_POST['specification_values'];
$price = $_POST['price'];
$stock = $_POST['stock'];

$specification_combinations = getCombinations($specification_values);
foreach ($specification_combinations as $combination) {
  $sku_code = generateSkuCode($product_id, $combination);

  $sql = "INSERT INTO skus (product_id, sku_code, specification_values, price, stock) VALUES ('$product_id', '$sku_code', '$combination', '$price', '$stock')";
  // 执行插入操作
}

4. Code Example

Now, let’s take a look at how to implement the multi-specification SKU function of products based on the above data structure in PHP.

Based on the above code examples and database design, you can realize the function of multi-specification SKU of products.

Summary

This article introduces a method based on PHP programming to realize the function of multi-specification SKU of products. Through database design and code examples, we can easily implement the management of multiple specifications of goods and the generation of SKUs in the e-commerce system. I hope this article will be helpful to you in your e-commerce system development.
