PHP and Vue development: How to obtain membership points for different types of goods after payment
Introduction:
In e-commerce platforms, membership points are a kind of A common incentive mechanism is to earn points by purchasing goods or completing specific tasks. However, there may be differences in how points are earned for different types of products. This article will combine PHP and Vue development to introduce how to obtain membership points for different types of goods after payment, and provide specific code examples. We hope that the explanation in this article can help developers better implement this function.
1. Back-end development (PHP):
- Database design:
Before starting PHP development, you first need to design an appropriate database table structure to store product information and Points information. The following is an example of the product table and points table design:
Product table (goods)
- id: Product ID
- name: Product name
- price: Product price
- type: Product type
- ...
Points table(points)
- id: Points ID
- goods_id: Product ID (associated product table)
- points: Number of points
- ...
- Web back-end interface development:
Next, use PHP to implement the interface for obtaining membership points for different types of products. The following is a simple example:
//Receive parameters passed by the front end
$goodsId = $_POST['goodsId'];
/ / Query product type
$goodsType = queryGoodsType($goodsId);
// Query member points based on product type
$points = queryPointsByType($goodsType);
// Return points information to the front end
echo json_encode(['points' => $points]);
// Method to query product type
function queryGoodsType($goodsId)
{
// 自行实现，例如从数据库中查询商品类型
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", 'root', '');
$stmt = $pdo->prepare("SELECT type FROM goods WHERE id=?");
$stmt->execute([$goodsId]);
$result = $stmt->fetch(PDO::FETCH_ASSOC);
return $result['type'];}
//Method to query points information
function queryPointsByType($goodsType)
{
// 自行实现，例如从数据库中查询对应商品类型的积分信息
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", 'root', '');
$stmt = $pdo->prepare("SELECT points FROM points WHERE goods_id IN (SELECT id FROM goods WHERE type=?)");
$stmt->execute([$goodsType]);
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
return $result;}
?>
In the above code, first receive the product ID parameter passed by the front end, and then query the product type through the queryGoodsType method. According to the product type, use the queryPointsByType method to query the corresponding member points information, and return the result to the front end in JSON format.
2. Front-end development (Vue):
- Create a Vue project:
Use Vue CLI and other tools to create a new Vue project, or directly introduce Vue into the HTML page .js library. - Front-end page development:
In the Vue page, implement the function of obtaining member points after payment. Here is a simple example:
<h2 id="支付成功-获取会员积分">支付成功，获取会员积分</h2>
<select v-model="selectedGoods" @change="getPoints">
<option v-for="item in goodsList" :key="item.id" :value="item.id">{{ item.name }}</option>
</select>
<p>会员积分: {{ points }}</p>
