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);
?>

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);
?>

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

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

cd point-mall

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 id="会员积分商城">会员积分商城</h1>
      <p>当前积分: {{ points }}</p>
      <h2 id="商品列表">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>

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');

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

npm run serve

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.
