Analysis of the mall order evaluation mechanism developed using PHP

1. Introduction
On modern e-commerce platforms, user evaluation is a very important function. User evaluations of products can help other users make purchasing decisions, and are also an important basis for merchants to understand user satisfaction and improve product quality. This article will introduce how to use the PHP developer mall order evaluation mechanism to add user evaluation functions to the e-commerce platform.

2. Database design
Before starting development, we first need to design a database table to store order and evaluation-related data. A basic database design is as follows:

  1. Order table (order):
    Field name type description
    order_id varchar(20) Order ID
    user_id int User ID
    product_id int product ID
    order_time datetime order time
  2. Product table (product):
    Field name type description
    product_id int product ID
    product_name varchar(50) product name
    price decimal(8,2) Product price
  3. User table (user):
    Field name type description
    user_id int User ID
    username varchar(20) User name
  4. Evaluation table (comment):
    Field name type description
    comment_id int Evaluation ID
    order_id varchar(20) Order ID
    user_id int User ID
    comment text Evaluation content
    comment_time datetime evaluation time
    star int rating

3. Evaluation function implementation

  1. Display orders to be evaluated
    We first need to display the user on the user center page List of orders to be evaluated. We can use PHP code to query the database, obtain the current user's order list to be evaluated, and display it on the page. The sample code is as follows:

4f390db700832c71b95880a170ec0472

  1. Submit evaluation
    When the user clicks the evaluation link, we need to insert the user's evaluation data into the evaluation table and update the evaluation status in the order table. When designing the evaluation table, pay attention to setting foreign key constraints to ensure the relationship between evaluation and orders. The sample code is as follows:

4. Administrator management evaluation
The administrator needs to be able to view Reviews from all users and perform operations on the reviews, such as deleting reviews, etc. We can add a review management page in the administrator backend to display a list of all users' reviews and provide a deletion function. The sample code is as follows:

The above is the basic implementation mechanism for order evaluation using PHP Developer City. Of course, in actual development, issues such as security, performance optimization, and permission control also need to be considered. This article only provides a simple reference. Hope it helps you!
