Discussion on the evaluation and complaint handling of mall after-sales service developed by PHP

With the rapid development of e-commerce, the importance of mall after-sales service has gradually emerged. Consumers’ evaluation of after-sales service directly affects the mall’s reputation and user retention rate. This article will discuss the after-sales service evaluation and complaint handling of the mall developed by PHP, and give some practical experience combined with code examples.

1. Evaluation system design

The mall's evaluation system is a platform for users to evaluate products and after-sales services. Through evaluation, you can intuitively understand the quality of products and after-sales services. In a mall developed in PHP, a simple evaluation system can be implemented through the following code example.

<?php
// 创建评价表的数据库表
CREATE TABLE `evaluations` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `order_id` int(11) NOT NULL,
  `goods_id` int(11) NOT NULL,
  `rate` int(11) NOT NULL,
  `content` varchar(255) NOT NULL,
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
);

// 用户评价商品
public function evaluateGoods($user_id, $order_id, $goods_id, $rate, $content) {
  $sql = "INSERT INTO `evaluations` (`user_id`, `order_id`, `goods_id`, `rate`, `content`) VALUES (?, ?, ?, ?, ?)";
  $stmt = $this->db->prepare($sql);
  $stmt->bind_param("iiiss", $user_id, $order_id, $goods_id, $rate, $content);
  $stmt->execute();
  $stmt->close();
}

// 获取商品评价列表
public function getGoodsEvaluations($goods_id) {
  $sql = "SELECT * FROM `evaluations` WHERE `goods_id` = ?";
  $stmt = $this->db->prepare($sql);
  $stmt->bind_param("i", $goods_id);
  $stmt->execute();
  $result = $stmt->get_result();
  $evaluations = $result->fetch_all(MYSQLI_ASSOC);
  $stmt->close();
  return $evaluations;
}
?>

Through the above code example, we can enable users to evaluate products and obtain the product evaluation list.

2. Complaint handling design

During the operation of the mall, it is inevitable that users will complain about after-sales service. A good complaint handling mechanism can help the mall improve its services and enhance user satisfaction. Below is a basic complaint handling code example.

<?php
// 创建投诉表的数据库表
CREATE TABLE `complaints` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `order_id` int(11) NOT NULL,
  `content` varchar(255) NOT NULL,
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
);

// 用户提交投诉
public function submitComplaint($user_id, $order_id, $content) {
  $sql = "INSERT INTO `complaints` (`user_id`, `order_id`, `content`) VALUES (?, ?, ?)";
  $stmt = $this->db->prepare($sql);
  $stmt->bind_param("iis", $user_id, $order_id, $content);
  $stmt->execute();
  $stmt->close();
}

// 获取投诉列表
public function getComplaints() {
  $sql = "SELECT * FROM `complaints`";
  $result = $this->db->query($sql);
  $complaints = $result->fetch_all(MYSQLI_ASSOC);
  return $complaints;
}

// 处理投诉
public function handleComplaint($complaint_id, $handle_result) {
  $sql = "UPDATE `complaints` SET `handle_result` = ? WHERE `id` = ?";
  $stmt = $this->db->prepare($sql);
  $stmt->bind_param("si", $handle_result, $complaint_id);
  $stmt->execute();
  $stmt->close();
}
?>

Through the above code examples, we can implement the functions of users submitting complaints, obtaining complaint lists, and handling complaints.

Summary:

In a mall developed by PHP, excellent after-sales service evaluation and complaint handling mechanism play an important role in the operation and user experience of the mall. By designing a reasonable evaluation system and complaint handling mechanism, the mall can help the mall improve its services and increase user satisfaction. It is hoped that the above code examples and practical experience can provide some reference for the after-sales service evaluation and complaint handling of malls developed in PHP.
