Title: Using the Layui framework to develop a shopping platform that supports instant group buying and coupons

Introduction:
With the development of e-commerce, shopping platforms have become a An important channel for purchasing goods. In order to attract users and enhance the shopping experience, it is important to develop a shopping platform that supports instant group buying and coupons. This article will introduce how to use the Layui framework to develop such a shopping platform and provide corresponding code examples.

1. Preparation

1. Install and configure the Layui framework
   Before starting development, we first need to install the Layui framework. You can download the latest version of the framework from the Layui official website (https://www.layui.com/) and configure it according to the official documentation.
2. Design database structure
   The shopping platform needs to store product information, user information, group purchase information, coupon information, etc. Based on requirements, design corresponding database tables and create relevant fields.

2. Develop a shopping platform

1. Product display page
   First, we need to develop a product display page to allow users to browse and select products. This page should display the name, price, pictures and other information of the product, and provide a purchase button.

HTML code example:

<div class="layui-container">
  <div class="layui-row">
    <div class="layui-col-md3">
      <img src="商品图片URL" alt="商品图片">
      <h3>商品名称</h3>
      <p>商品价格</p>
      <button class="layui-btn layui-btn-normal">购买</button>
    </div>
    <!-- 其他商品 -->
  </div>
</div>

2. Group buying function
   In order to support instant group buying, we need to develop a group buying function. Users can join an ongoing group buying activity by clicking the group buying button.

HTML code example:

<div class="layui-col-md3">
  <img src="商品图片URL" alt="商品图片">
  <h3>商品名称</h3>
  <p>商品价格</p>
  <button class="layui-btn layui-btn-normal" onclick="joinGroupBuy(商品ID)">团购</button>
</div>

JavaScript code example:

function joinGroupBuy(商品ID) {
  // 发送HTTP请求，加入团购活动
  layui.$.ajax({
    url: "join_groupbuy.php",
    method: "POST",
    data: { productID: 商品ID },
    success: function (res) {
      layui.layer.msg("已成功加入团购活动！");
    },
    error: function (xhr, textStatus, errorThrown) {
      layui.layer.msg("加入团购活动失败！");
    }
  });
}

3. Coupon function
   In order to support the coupon function, we need to develop a Coupon page allows users to view and receive coupons.

HTML code example:

<div class="layui-container">
  <div class="layui-row">
    <div class="layui-col-md3">
      <h3>优惠券名称</h3>
      <p>优惠券描述</p>
      <button class="layui-btn layui-btn-normal" onclick="claimCoupon(优惠券ID)">领取</button>
    </div>
    <!-- 其他优惠券 -->
  </div>
</div>

JavaScript code example:

function claimCoupon(优惠券ID) {
  // 发送HTTP请求，领取优惠券
  layui.$.ajax({
    url: "claim_coupon.php",
    method: "POST",
    data: { couponID: 优惠券ID },
    success: function (res) {
      layui.layer.msg("已成功领取优惠券！");
    },
    error: function (xhr, textStatus, errorThrown) {
      layui.layer.msg("领取优惠券失败！");
    }
  });
}
