Compilation of code examples of SKU management functions commonly used in PHP mall development

With the vigorous development of the e-commerce industry, more and more companies choose to open their own stores online 's mall. In mall development, SKU (Stock Keeping Unit) management is a very important function, which can help merchants better manage and display products.

This article will compile some code examples of SKU management functions commonly used in PHP mall development to help developers better understand and apply them to actual projects.

1. The concept of SKU

Before starting to write the code for the SKU management function, we must first understand what a SKU is. SKU refers to a set of unique identifiers used by merchants to distinguish and manage different products. Each SKU corresponds to a specific product, which contains the attributes, specifications, price and other information of the product.

In the mall, products may have multiple attributes and specifications, such as color, size, style, etc. Different combinations of attributes and specifications will form different SKUs. Through the SKU management function, merchants can easily add, modify and delete SKUs to meet the needs of different customers.

2. Data structure design for SKU management

In actual development, we can use the database to store and manage SKU-related data. The following is a simple data structure design example for SKU management:

1. products table (products_table)
2. id: product ID
3. name: product name
4. description：Product description
5. ...
6. Attributes table（attributes_table）
7. id：Attribute ID
8. name：Attribute name
9. ...
10. Specifications table (specifications_table)
11. id: specification ID
12. name: specification name
13. ...
14. SKU table (skus_table)
15. id: SKU ID
16. product_id: product ID
17. attribute_id: attribute ID
18. specification_id: specification ID
19. price：price
20. stock：stock
21. ...
22. SKU attribute table (sku_attributes_table)
23. id: SKU attribute ID
24. sku_id: SKU ID to which it belongs
25. attribute_id: attribute ID
26. value: attribute value
27. ...
28. SKU specifications table (sku_specifications_table)
29. id: SKU specification ID
30. sku_id: SKU ID to which it belongs
31. specification_id: Specification ID
32. value: Specification value
33. .. .

The above is a simple data structure design example for SKU management, which developers can modify and expand according to specific needs.

3. Code examples of SKU management functions

The following are code examples of some commonly used SKU management functions for reference:

1. Add SKU

function addSKU($product_id, $attribute_values, $specification_values, $price, $stock) {
    // 创建SKU记录
    $sku_id = createSKURecord($product_id, $price, $stock);
    
    // 添加SKU属性记录
    foreach ($attribute_values as $attribute_id => $value) {
        addSKUAttribute($sku_id, $attribute_id, $value);
    }
    
    // 添加SKU规格记录
    foreach ($specification_values as $specification_id => $value) {
        addSKUSpecification($sku_id, $specification_id, $value);
    }
}

2. Modify SKU

function updateSKU($sku_id, $attribute_values, $specification_values, $price, $stock) {
    // 更新SKU记录
    updateSKURecord($sku_id, $price, $stock);
    
    // 更新或添加SKU属性记录
    foreach ($attribute_values as $attribute_id => $value) {
        if (SKUAttributeExists($sku_id, $attribute_id)) {
            updateSKUAttribute($sku_id, $attribute_id, $value);
        } else {
            addSKUAttribute($sku_id, $attribute_id, $value);
        }
    }
    
    // 更新或添加SKU规格记录
    foreach ($specification_values as $specification_id => $value) {
        if (SKUSpecificationExists($sku_id, $specification_id)) {
            updateSKUSpecification($sku_id, $specification_id, $value);
        } else {
            addSKUSpecification($sku_id, $specification_id, $value);
        }
    }
}

3. Delete SKU

function deleteSKU($sku_id) {
    // 删除SKU属性记录
    deleteSKUAttributes($sku_id);
    
    // 删除SKU规格记录
    deleteSKUSpecifications($sku_id);
    
    // 删除SKU记录
    deleteSKURecord($sku_id);
}

The above code example is just a simple demonstration, the specific implementation method and logic Will vary based on project needs. Developers can modify and optimize it according to their own project requirements.

Summary:

SKU management function plays an important role in PHP mall development. Through good database design and code writing, developers can easily add, modify, and delete SKUs. I hope the code examples compiled in this article will be helpful to PHP mall developers.
