Use PHP framework CodeIgniter to develop an efficient after-sales management system and provide after-sales service

With the rapid development of the e-commerce field, after-sales management has become an issue of great concern. In order to improve the efficiency and quality of after-sales services, many companies have begun to introduce after-sales management systems. This article will introduce how to use the PHP framework CodeIgniter to develop an efficient after-sales management system to achieve better after-sales service.

1. System requirements analysis
A complete after-sales management system should have the following functional requirements:

1. User registration and login;
2. Consumer complaint function;
3. After-sales service management function;
4. After-sales service record query and statistical analysis function;

2. System design

1. Architecture Design
   This system adopts MVC architecture design, which divides the system into three parts: Model, View and Controller. The Model layer is mainly responsible for interacting with the database, including adding, deleting, modifying, and querying operations on the database; the View layer is mainly responsible for rendering pages and interacting with users; the Controller layer plays the role of a bridge, converting user requests into data requests, and converting the results Passed to the View layer; at the same time, the Controller layer will also respond to data requests from the Model layer.
2. Database Design
   This system database will contain 4 tables, namely user table, complaint table, service table and statistics table.

3. System implementation

1. User registration and login function
   In order to protect the user’s information security, this system requires users to provide their real name and password when registering Phone number. User information is stored in the User table, and the active record provided by CodeIgniter is used to perform addition, deletion, modification and query operations.
2. Consumer Complaint Function
   Users can make complaints through the complaint function, and the complaint information is stored in the Complaint table. After receiving a complaint, the system administrator can provide corresponding after-sales service processing based on the user's complaint information.
3. After-sales service management function
   The administrator has the right to handle complaints. After the administrator handles the complaint, the system will send a text message notification to the user based on the administrator's processing status. The after-sales service management function mainly implements the following functions: handling complaints, viewing complaints, querying after-sales service records, etc.
4. After-sales service record query and statistical analysis function
   Provides users with the function of querying and statistically analyzing after-sales service records. The system administrator can also view the user's after-sales service records. At the same time, administrators can also perform statistical analysis on users' after-sales service records and make decisions based on the data results.

4. System deployment and testing
This system uses the php mysql platform. After installing php and mysql, you need to upload the system source code to the specified directory on the server and use mysql to import the default database data. After completing the above operations, the system is ready for online use. During the testing phase, the system should be rigorously tested to prevent system vulnerabilities.

5. Summary
This article uses the PHP framework CodeIgniter to develop an efficient after-sales management system, which makes after-sales management simpler and faster, and provides enterprises with more professional and complete after-sales services. It also provides a new reference solution for today's e-commerce.
