With the rapid development of the e-commerce industry, more and more businesses are choosing to open their malls online. In mall development, SKU (Stock Keeping Unit) management is especially important. It helps merchants efficiently manage product information and ensures that product attributes, specifications, and inventory are accurately controlled.
This article will organize common SKU management functions through practical PHP code examples to help developers understand and apply them to real projects.
Before developing the SKU management functionality, we first need to clarify what SKU is. SKU stands for Stock Keeping Unit, a code used by merchants to uniquely identify and differentiate different products. Each SKU represents a specific product and contains information such as product attributes, price, size, etc.
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 proper SKU management, merchants can easily manage different versions of a product to meet the needs of different customers.
In actual development, SKU-related data is usually stored in a database. Below is a simple data structure design example for SKU management:
Product Table (products_table):
Attribute Table (attributes_table):
Specification Table (specifications_table):
SKU Table (skus_table):
SKU Attribute Table (sku_attributes_table):
SKU Specification Table (sku_specifications_table):
Developers can modify or expand the above data structure according to actual needs.
Next, we will show some commonly used PHP code examples for SKU management functions for developers to refer to.
function addSKU($product_id, $attribute_values, $specification_values, $price, $stock) {
// Create SKU record
$sku_id = createSKURecord($product_id, $price, $stock);
// Add SKU attribute records
foreach ($attribute_values as $attribute_id => $value) {
addSKUAttribute($sku_id, $attribute_id, $value);
}
// Add SKU specification records
foreach ($specification_values as $specification_id => $value) {
addSKUSpecification($sku_id, $specification_id, $value);
}
}
function updateSKU($sku_id, $attribute_values, $specification_values, $price, $stock) {
// Update SKU record
updateSKURecord($sku_id, $price, $stock);
// Update or add SKU attribute records
foreach ($attribute_values as $attribute_id => $value) {
if (SKUAttributeExists($sku_id, $attribute_id)) {
updateSKUAttribute($sku_id, $attribute_id, $value);
} else {
addSKUAttribute($sku_id, $attribute_id, $value);
}
}
// Update or add SKU specification records
foreach ($specification_values as $specification_id => $value) {
if (SKUSpecificationExists($sku_id, $specification_id)) {
updateSKUSpecification($sku_id, $specification_id, $value);
} else {
addSKUSpecification($sku_id, $specification_id, $value);
}
}
}
function deleteSKU($sku_id) {
// Delete SKU attribute records
deleteSKUAttributes($sku_id);
// Delete SKU specification records
deleteSKUSpecifications($sku_id);
// Delete SKU record
deleteSKURecord($sku_id);
}
SKU management is an essential feature in PHP mall development. Through well-designed database structures and efficient code implementation, developers can implement functions for adding, updating, and deleting SKUs, while also meeting the diverse needs of e-commerce platforms. It is hoped that the code examples provided in this article will help PHP mall developers in their projects.
