Comprehensive analysis of auction and resale mall system source code

In today's digital era, electronic auction and resale systems are gradually becoming an important part of commercial transactions. This article will provide a comprehensive introduction to the source code of a mall system that integrates backend management, product listing, user bidding, resale and payment functions. The system uses PHP as the back-end development language, and the front-end is built using the UNIAPP framework, providing users with a seamless cross-platform experience.

System core gameplay

Product listing: Administrators or authorized users can easily add products for listing in the background. Detailed description, price and relevant auction rules can be set for each product.
Session setting: Administrators can create and set different auction sessions, including session names, start time, end time, etc. This provides a flexible management method for auction activities for different products or different time periods.
User auction: Registered users can browse and participate in auction activities in the system. After the auction starts, users can grab orders according to the rules and strive to obtain the product they want at the best price.
Pick-up and resale: Users who successfully grab orders can choose to pick up the goods directly or resell the goods to other users. For resale operations, the system will automatically calculate the mark-up percentage according to the rules set in the background to ensure the fairness of the transaction.
Handling fee payment: In order to maintain the normal operation of the system, players need to pay a certain handling fee when consigning goods. The system supports multiple payment methods, including balance payment, Alipay APP payment, Alipay H5 payment and WeChat APP payment, providing users with a convenient payment experience.
Points system: After picking up the goods, users will earn corresponding points based on the value of the goods. These points can be redeemed for other goods in the points mall, providing users with additional benefits and incentives.
technical architecture

Back-end PHP: As a widely used server-side scripting language, PHP has become the first choice for this system because of its efficiency, flexibility and ease of learning. The PHP back-end is responsible for handling user requests, data storage and retrieval, and communicating with the front-end.
Front-end UNIAPP: UNIAPP is a framework that uses Vue.js to develop all front-end applications. It can be compiled into iOS, Android, H5, and various Mini programs (WeChat/Alipay/Baidu/Headline/QQ/Dingnail, etc.). This means that users can use the system on different platforms and enjoy a consistent user experience.
