How to use PHP and Vue to develop and update member points value according to product type after payment

With the popularity of mobile payment, more and more merchants are beginning to use Internet technology Turn offline transactions into online payments. In this process, merchants often hope to update the member's points value based on the type of goods purchased by the user. This article will introduce how to use PHP and Vue technologies to implement this function, and give specific code examples.

1. Back-end development (PHP)

1. Create database table

First, we need to create a database table to store member information, including membership Fields such as ID, member name, member points, member purchases, etc. Create the following table structure:

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

2. Write PHP code to update membership points

In the PHP code, when the user pays successfully, we need to Update the points value of the corresponding member. Write the following PHP code:

<?php
  $productId = $_POST['product_id']; // 获取商品ID
  $memberId = $_POST['member_id']; // 获取会员ID

  // 根据商品ID查询对应的积分增加值
  $points = getPointsByProductId($productId);

  // 更新会员积分
  updateMemberPoints($memberId, $points);

  // 返回更新结果
  echo json_encode(['status' => 'success', 'message' => '积分更新成功']);

  // 根据商品ID查询积分增加值的函数
  function getPointsByProductId($productId) {
    // 根据产品ID查询对应的积分增加值
    // 这里可以根据具体业务逻辑自行实现查询逻辑
    $points = 0;
    switch ($productId) {
      case 1:
        $points = 10;
        break;
      case 2:
        $points = 20;
        break;
      case 3:
        $points = 30;
        break;
      default:
        $points = 0;
        break;
    }
    return $points;
  }

  // 更新会员积分的函数
  function updateMemberPoints($memberId, $points) {
    // 根据会员ID更新会员的积分
    // 这里可以根据具体业务逻辑自行实现更新逻辑
  }
?>

In the above code, we obtain the product ID and member ID passed by the user after successful payment, query the corresponding points increase value based on the product ID, and then update the member's points.

2. Front-end development (Vue)

1. Create Vue project

First, we need to create a Vue project, which can be quickly done using Vue CLI create. Execute the following command in the terminal:

$ vue create member-points

2. Write Vue component

In the Vue project, we need to create a component to implement the function of updating member points after payment. Create the MemberPoints.vue component in the src/components directory and write the following code:

<template>
  <div>
    <h2 id="支付成功-更新会员积分">支付成功，更新会员积分</h2>
    <form @submit.prevent="updatePoints">
      <label>商品ID:</label>
      <input type="number" v-model="productId">
      <label>会员ID:</label>
      <input type="number" v-model="memberId">
      <button type="submit">更新积分</button>
    </form>
  </div>
</template>

<script>
export default {
  data() {
    return {
      productId: '',
      memberId: ''
    }
  },
  methods: {
    updatePoints() {
      // 发送请求到后端更新会员积分
      fetch('/update_points.php', {
        method: 'POST',
        body: JSON.stringify({
          product_id: this.productId,
          member_id: this.memberId
        })
      })
      .then(response => response.json())
      .then(data => {
        console.log(data);
        // 更新成功后的处理逻辑
      })
      .catch(error => {
        console.error(error);
        // 更新失败后的处理逻辑
      });
    }
  }
}
</script>

In the above code, we created a form for entering the product ID and member ID, and sent a POST request to the post through the fetch function Use the update_points.php file on the client to update membership points.

3. Using the MemberPoints component in App.vue

In the src/App.vue file, we can use the MemberPoints component to display the function of updating member points after payment. Modify the App.vue file as follows:

<template>
  <div>
    <h1 id="支付后会员积分更新">支付后会员积分更新</h1>
    <MemberPoints></MemberPoints>
  </div>
</template>

<script>
import MemberPoints from './components/MemberPoints.vue'

export default {
  components: {
    MemberPoints
  }
}
</script>

So far, we have completed using PHP and Vue to develop the function of updating member points value according to product type after payment.

Summary:

By using PHP and Vue technologies, this article introduces how to implement the function of updating member points value according to the product type after payment. The back-end PHP code is used to process the update logic of member points, and the front-end Vue code is used to display and trigger the update operation of member points. Hope this article is helpful to everyone.
