Design and implementation of after-sales service system for PHP mall

As online shopping becomes more and more popular in today's society, more and more merchants use online platforms to sell products, and PHP, as a widely used server-side scripting language, has naturally become the first choice for many mall systems. However, after purchasing goods, consumers' after-sales service needs gradually increase. How to design an efficient PHP mall after-sales service system has become an important issue.

1. Demand analysis of after-sales service system

The after-sales services involved in the PHP mall mainly include return and exchange and repair services. Returns and exchanges refer to consumers applying for returns or exchanges when the goods they receive have quality problems, inappropriate sizes, colors that do not match the actual products, etc.; while repair services refer to when consumers have problems during use. Perform repairs or maintenance.

Therefore, the after-sales service system of the PHP mall should have the following functions:

1. User feedback: Allow users to submit after-sales service applications, including return and exchange requests and repair service requests.
2. Service processing: Mall staff receive users’ after-sales service requests, determine whether the service conditions are met, and process them as soon as possible.
3. Notification of processing results: Mall staff will notify users based on the processing results, including refund information, logistics information, etc.
4. Establish an audit mechanism: The mall needs to establish an audit mechanism to ensure that after-sales service processing is fair and legal.
5. Service data statistics: The mall needs to collect statistics on after-sales service data so that problems can be discovered in a timely manner and optimized and improved.

2. Design and implementation of after-sales service system

1. Database design

The after-sales service system needs to use a database to store application information and review Information, processing results and other data. For PHP malls, common data table designs include:

1). Service application form: used to store after-sales service request information submitted by users, including user ID, application time, service type, reason, etc.

2). Audit form: a record form for mall staff to review after-sales service applications, including application ID, reviewer ID, review time, review results, etc.

3). Processing result table: a record table of after-sales service applications processed by mall staff, including application ID, processor ID, processing time, processing results, etc.

2. Implementation of after-sales service system

When implementing the after-sales service system, you can consider using the MVC model for development. Specifically, it can be implemented using the Yii framework.

(1) Model layer

The model layer is responsible for interacting with the database, including data addition, editing, query and other operations. For the after-sales service system, three models can be defined:

1). ServiceRequest: Corresponds to the service application form and provides related operation methods, such as create, delete, findByPk, etc.

2). ServiceAudit: Corresponds to the audit form and provides related operation methods.

3). ServiceProcess: Corresponds to the processing result table and provides related operation methods.

(2) View layer

The view layer is mainly responsible for the performance of the UI. For the after-sales service system, the following views can be designed:

1). Service application form: collects after-sales service application information submitted by users.

2). Review list view: Displays application records to be reviewed.

3). Processing results view: Displays processed application records.

4). Statistics page: Displays after-sales service statistical information, such as completion rate, service type proportion, etc.

(3) Controller layer

The controller layer is responsible for controlling the business logic process and connecting the model and the view. For the after-sales service system, the following program flow can be implemented:

1). The user submits an after-sales service request and submits it to the application form.

2). After the application form is successfully operated, it will enter the pending review list.

3). The mall staff will review the application and enter the pending list after successful review.

4). The mall staff processes the application. After the processing is completed, it enters the processed list.

5). The mall staff sends a processing result notification to the user, and the after-sales service is completed.

3. Summary

The after-sales service system of the PHP mall is an important part of the services provided by the online mall. Its functional perfection and efficient operation play a key role in the development of the mall. When designing and implementing, it is necessary to fully consider user experience, ease of use and operational standardization, and continuously optimize and improve. At the same time, during the implementation process, it is also necessary to pay attention to the security and reliability of data to ensure the high-quality operation of the after-sales service system.
