PHP and Vue: How to implement points mall shopping with member points

Introduction:
Points mall is a common form of promotional activities in modern e-commerce platforms , users can use their points to redeem products or participate in activities. In this article, we will introduce how to use PHP and Vue to implement a simple membership points mall shopping function, and provide specific code examples.

1. Back-end implementation (PHP):

1. Create a database table
First, we need to create a database table to store member points information. The following is a simple table structure example:

CREATE TABLE `members` (
   `id` INT(11) NOT NULL AUTO_INCREMENT,
   `name` VARCHAR(50) NOT NULL,
   `points` INT(11) NOT NULL DEFAULT '0',
   PRIMARY KEY (`id`)
);

2. Obtain member points information
Next, we need to write a PHP interface to obtain member point information. In this example, we will use a simple GET request to obtain member points information.

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "username", "password", "database");

if (!$conn) {
   die("连接失败: " . mysqli_connect_error());
}

// 获取会员积分信息
$sql = "SELECT * FROM members WHERE id = " . $_GET['memberId'];
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
   // 输出会员积分信息
   while($row = mysqli_fetch_assoc($result)) {
      echo "会员ID: " . $row['id'] . ", 积分: " . $row['points'];
   }
} else {
   echo "会员不存在";
}

// 关闭连接
mysqli_close($conn);
?>

Copy after login

3. Update member points information
After the user redeems gifts or participates in activities, we need to update the member's points information. The following is a sample interface for updating a member's points information. In this example, we assume that each time you redeem an item, a certain amount of points is consumed.

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "username", "password", "database");

if (!$conn) {
   die("连接失败: " . mysqli_connect_error());
}

// 更新会员积分
$sql = "UPDATE members SET points = points - " . $_POST['points'] . " WHERE id = " . $_POST['memberId'];

if (mysqli_query($conn, $sql)) {
   echo "积分更新成功";
} else {
   echo "积分更新失败: " . mysqli_error($conn);
}

// 关闭连接
mysqli_close($conn);
?>

Copy after login

2. Front-end implementation (Vue):

1. Create a Vue project
First, we need to use the Vue CLI to create a new Vue project. Open the terminal and execute the following command:

vue create point-mall

Copy after login

Configure according to the prompts, and enter the project directory after the creation is successful:

cd point-mall

Copy after login

2. Create a page component
Create a file named Home in the src directory The Vue component of .vue is used to display membership points and product lists. The following is a simplified sample code:

<template>
   <div>
      <h1>会员积分商城</h1>
      <p>当前积分: {{ points }}</p>
      <h2>商品列表：</h2>
      <ul>
         <li v-for="item in items" :key="item.id">
            {{ item.name }} - {{ item.points }}积分
            <button @click="exchange(item)">兑换</button>
         </li>
      </ul>
   </div>
</template>

<script>
export default {
   data() {
      return {
         points: 0,
         items: [
            { id: 1, name: '商品1', points: 10 },
            { id: 2, name: '商品2', points: 20 },
            { id: 3, name: '商品3', points: 30 }
         ]
      };
   },
   methods: {
      exchange(item) {
         // 发送POST请求更新积分
         fetch('/api/update_points', {
            method: 'POST',
            body: JSON.stringify({
               memberId: 1, // 替换为实际会员ID
               points: item.points
            }),
            headers: {
               'Content-Type': 'application/json'
            }
         })
         .then(response => response.json())
         .then(data => {
            if (data.success) {
               alert('兑换成功');
               // 更新积分
               this.points -= item.points;
            } else {
               alert('兑换失败');
            }
         })
         .catch(error => {
            console.error('错误:', error);
         });
      }
   },
   mounted() {
      // 获取会员积分信息
      fetch('/api/get_points?memberId=1') // 替换为实际会员ID
         .then(response => response.text())
         .then(data => {
            this.points = data;
         })
         .catch(error => {
            console.error('错误:', error);
         });
   }
};
</script>

Copy after login

3. Configure routing and startup projects
Next, we need to configure routing and startup projects. Open the main.js file in the src directory and add the following code:

import Home from './Home.vue';
import VueRouter from 'vue-router';

Vue.use(VueRouter);

const router = new VueRouter({
   routes: [
      { path: '/', component: Home }
   ]
});

new Vue({
   router,
   render: h => h(Home)
}).$mount('#app');

Copy after login

4. Start the project
Execute the following command in the terminal to start the project:

npm run serve

Copy after login

Visit http://localhost :8080 to see the member points mall page.

Summary:
Through the above examples, we can see how to use PHP and Vue to implement a simple points mall shopping function for member points. Obtain and update member points information through the back-end PHP interface, display member points and product lists through the front-end Vue component, and implement the point redemption function. This is just a simple example. In actual applications, security, user authentication and other issues need to be taken into consideration, but this example can be used as a basic framework on which you can expand and optimize.
