How to conduct user evaluation and complaint handling of PHP flash sale system

How to conduct user evaluation and complaint handling of the PHP flash sale system requires specific code examples

With the rapid development of the e-commerce industry, flash sale activities have become an important way to attract users important means. However, due to the large number of participants, flash sale activities often face problems with user reviews and complaints. This article will introduce how to handle user reviews and complaints in the PHP flash sale system, and provide specific code examples.

1. User evaluation processing

1. How to determine evaluation
   Users can evaluate through different methods such as text comments and ratings. In the PHP flash sale system, we can build an evaluation module to display the user evaluation list at the bottom of the product details page and provide an evaluation input box and submit button.
2. Storing evaluation data
   In PHP, we can use a database to store user evaluation data. Create an evaluation table, including evaluator ID, product ID, evaluation content, rating and other fields. When the user submits an evaluation, the evaluation data is inserted into the database.

The following is a sample code for creating a review table in the database:

CREATE TABLE `evaluation` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `product_id` int(11) NOT NULL,
  `content` text NOT NULL,
  `score` int(11) NOT NULL,
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3. Display review data
   At the bottom of the product details page, use the PHP code from Read the evaluation data from the database and display it to the user in the form of a list. The code example is as follows:

<?php
$productId = 1; // 假设商品ID为1

// 查询评价数据
$sql = "SELECT * FROM `evaluation` WHERE `product_id` = $productId";
$result = mysqli_query($conn, $sql);

// 循环输出评价数据
while ($row = mysqli_fetch_assoc($result)) {
  echo "<p>用户" . $row['user_id'] . "评价：" . $row['content'] . "</p>";
}
?>

4. User's additional evaluation
   Some users may add or modify their evaluations later. In order to support the user's additional evaluation function, we can add an updated_at field to the evaluation table to store the last modification time of the evaluation. When the user adds a review, we only need to update the corresponding record in the review table.

2. User Complaint Handling

1. Provide Complaint Channels
   In order to discover and resolve user complaints in a timely manner, we need to provide a convenient complaint method in the flash sale system channel. User complaint information can be collected through a complaint page or by contacting customer service.
2. Storing complaint data
   Like evaluation data, user complaint data should also be stored in the database. Create a complaint table that contains complainant ID, complaint content, complaint time and other fields, and insert the user's complaint data into the database.

The following is a sample code for creating a complaint table in the database:

CREATE TABLE `complaint` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `content` text NOT NULL,
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3. Handling complaints
   When the user submits a complaint, we need to respond to the complaint in a timely manner for processing. The handling method can be determined according to the specific situation, which can include accepting complaints, communicating and resolving them, making compensation, etc. Regardless of the processing results, timely feedback should be given to the user and the processing results should be recorded in the database.

The following is a sample code for handling user complaints:

<?php
$userId = 1; // 假设用户ID为1
$content = "投诉内容"; // 假设用户投诉内容为"投诉内容"

// 将投诉数据插入到投诉表
$sql = "INSERT INTO `complaint` (`user_id`, `content`) VALUES ($userId, '$content')";
$result = mysqli_query($conn, $sql);

// 处理投诉逻辑
// ...
?>

The above is a detailed introduction and code example on how to conduct user evaluation and complaint handling of the PHP flash sale system. Through reasonable design and implementation, we can better handle user reviews and complaints, improve user experience, and increase user stickiness. Hope this article is helpful to you!
