PHP and Vue: How to automatically update membership points based on the payment amount

In modern society, many companies and merchants will provide customers with a membership points system. In this way To encourage customer consumption and enhance customer loyalty. For some small and medium-sized enterprises, many will choose to use PHP and Vue to develop their own websites or malls and implement such membership points functions.

This article will use specific code examples to introduce how to use PHP and Vue to automatically update membership points based on the payment amount.

1. Backend Development (PHP)
   First, we need to write code in the backend to handle the logic of payment and points update. We can use PHP to accomplish this task.

(1) Create a database table
First, we need to create a database table named "members" to store member information and points.

CREATE TABLE members (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(50),
  points INT DEFAULT 0
);

(2) Add members and update points
Next, we need to write PHP code to add new members and update points.

<?php
// 连接到数据库
$conn = mysqli_connect("localhost", "username", "password", "database_name");

// 检查连接是否成功
if (!$conn) {
    die("连接数据库失败: " . mysqli_connect_error());
}

// 添加新会员
$name = $_POST['name'];
$sql = "INSERT INTO members (name) VALUES ('$name')";
if (mysqli_query($conn, $sql)) {
    echo "新会员添加成功";
} else {
    echo "添加会员失败: " . mysqli_error($conn);
}

// 更新积分
$points = $_POST['points'];
$member_id = $_POST['member_id'];
$sql = "UPDATE members SET points = points + $points WHERE id = $member_id";
if (mysqli_query($conn, $sql)) {
    echo "积分更新成功";
} else {
    echo "积分更新失败: " . mysqli_error($conn);
}

// 关闭数据库连接
mysqli_close($conn);
?>

2. Front-end development (Vue)
   Next, we need to use Vue to handle the front-end payment and points update functions.

(1) Create a Vue component containing payment form and points update logic.

<template>
  <div>
    <form @submit="handlePayment">
      <label for="amount">支付金额:</label>
      <input type="number" id="amount" v-model="amount" required>
      <button type="submit">支付</button>
    </form>
  </div>
</template>

<script>
export default {
  data() {
    return {
      amount: 0,
    };
  },
  methods: {
    handlePayment(event) {
      event.preventDefault();

      // 调用后端API来添加新会员
      axios
        .post('/api/addMember', { name: 'John Doe' })
        .then((response) => {
          console.log(response.data);
        })
        .catch((error) => {
          console.error(error);
        });

      // 调用后端API来更新积分
      axios
        .post('/api/updatePoints', { member_id: 1, points: this.amount })
        .then((response) => {
          console.log(response.data);
        })
        .catch((error) => {
          console.error(error);
        });
    },
  },
};
</script>

3. Integrate back-end and front-end
   Finally, we need to integrate the back-end PHP code and the front-end Vue code.

In the PHP project, create a file named "api.php" and add the following code in it.

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $request_uri = $_SERVER['REQUEST_URI'];

    if ($request_uri === '/api/addMember') {
        // 添加会员的代码
    }

    else if ($request_uri === '/api/updatePoints') {
        // 更新积分的代码
    }
}
?>

In the Vue project, introduce the Vue components for payment and points update into the required pages.

<template>
  <div>
    <h1>Pay and Update Points</h1>
    <payment-form></payment-form>
  </div>
</template>

<script>
import PaymentForm from './PaymentForm.vue';

export default {
  components: {
    PaymentForm,
  },
};
</script>

The above is a code example that uses PHP and Vue to automatically update membership points based on the payment amount. In this way, we can easily implement a simple member points system and update members' points based on the payment amount. Of course, this is just a basic example, and more business requirements and security measures need to be considered in actual systems. Hope this article is helpful to you!
