How to build a complete product classification and commodity management system in PHP mall development?

With the popularization of the Internet and the rapid development of e-commerce, more and more merchants have begun to transfer their business online. In this context, various e-commerce platforms and malls have emerged. In the process of building a mall, the design of product classification and commodity management systems is very important.

As a PHP developer, we need to understand how to build a complete product classification and merchandise management system. This article will introduce how to build such a system, starting from actual needs, analyzing and implementing it from a technical perspective.

1. Demand analysis

To build a product classification and commodity management system, you first need to conduct demand analysis to understand the actual needs of the mall and the user's usage habits and needs. The following is a simple requirements analysis:

1. Product Category

1.1 Category Management

• Supports adding, modifying, and deleting categories;
• Supports hierarchical relationships of categories;
• Supports sorting of categories.

1.2 Category display

• When the category is displayed in the foreground, it supports the display of first-level and second-level categories;
• Click on the category to display lower-level categories or Product list.

2. Product Management

2.1 Product Attributes

• Supports adding, modifying, and deleting product attributes;
• Support unified platform attributes and customized non-platform attributes;
• Support attribute type, value, unit, and sorting.

2.2 Product Management

• Supports adding, modifying, and deleting products;
• Supports basic attributes of products, such as name, price, inventory, status, etc. ;
• Supports batch import and export of products.

3. Other requirements

• Support product search and filtering;
• Support shopping cart and order management;
• Support product evaluation and user comments;
• Support product recommendations and promotions, etc.

2. Technical Implementation

After understanding the requirements, we need to analyze and implement this system from a technical perspective. The following is the specific implementation plan:

1. Database design

Based on demand analysis, we need to design the following tables:

• category: classification Table, including classification id, name, parent id, sorting and other fields;
• attribute: attribute table, including attribute id, name, type, unit, sorting and other fields;
• attribute_value : Attribute value table, including attribute value id, attribute id, value, sorting and other fields;
• product: Product table, including product id, name, price, inventory, status and other fields;
• product_attribute: product attribute table, including product id, attribute id, attribute value id and other fields.

2. Implementing classification management

Category management functions include adding, modifying, deleting categories, and supporting hierarchical relationships and sorting of categories. Regarding the hierarchical relationship of categories, we can use the parent id to achieve it. If the parent id is 0, it is the top category. Sorting of categories can be achieved by setting a sort field.

3. Realize classified display

Categorized display is a way for users to browse products. We can do this by recursively traversing subcategories, or using a tree structure. When clicking a category, you can query the corresponding subcategory and product list based on the category ID.

4. Implement product attributes

Product attributes include platform attributes and non-platform attributes, which can be distinguished by a type field. Platform attributes refer to attributes that most products have, such as color, size, etc. Non-platform attributes refer to attributes that are unique to certain special products, such as movie directors and actors, etc.

Attribute values ​​can be stored in another table. Each attribute corresponds to multiple attribute values, and there is a one-to-one correspondence between attribute values ​​and attributes.

5. Realize product management

Product management includes adding, modifying, and deleting products, as well as supporting basic attributes of products such as name, price, inventory, and status. Batch import and export of products can be implemented using CSV files or Excel files.

6. Implement shopping cart and order management

The shopping cart function is to facilitate users to add products to the shopping cart at any time without having to purchase immediately. Order management includes functions such as generating orders, querying orders, shipping, returning and canceling orders. Regarding the generation and payment of orders, a third-party payment platform can be used.

7. Realize product reviews and evaluations

Users can evaluate and comment on products. A review is an evaluation of the overall quality of a product, while a review is a review of specific aspects of the product. Evaluations and comments can be implemented in the form of star ratings and text comments.

8. Realizing product recommendations and promotions, etc.

Product recommendation can be implemented using collaborative filtering, which is to recommend related products based on the user's behavior and preferences.

Promotional activities include discounts, discounts, gifts, etc. In specific implementation, different activity rules can be adopted according to different types of promotional activities.

3. Summary

This article briefly introduces how to build a complete product classification and commodity management system in PHP mall development. Through the explanation of requirements analysis and technical implementation, I hope to be able to provide you with some help. In actual development, you also need to consider issues such as performance optimization, security, and scalability, and hope to improve your capabilities through continuous learning and practice.
