The second-hand recycling website developed using PHP supports the return/exchange function

As people's awareness of environmental protection continues to increase, the second-hand recycling business is becoming more and more popular. Many people like to buy second-hand goods, which not only saves money, but also contributes to environmental protection. In second-hand recycling websites, it is very important to support return/exchange functions. This article will introduce how to use PHP to develop a second-hand recycling website and add return/exchange functions.

First, we need to create a database to store product and order information. We can use a MySQL database to create a database named "recycle" and create two tables in it: a product table named "products" and an order table named "orders".

The product table contains the following columns:

• id (primary key, auto-increment)
• name (product name)
• description (product description)
• price (product price)
• image (product image path)

The order table contains the following columns:

• id (primary key , self-increasing)
• product_id (id of the associated product table)
• user_name (user name)
• email (user email)
• address (user address )
• order_type (order type, 1 means purchase, 2 means return/exchange)
• create_time (order creation time)

Next, we have to write PHP code to handle return/exchange functionality. First, we need to display the user's order list and let the user select the order they want to return/exchange. We can get the user's order list by querying the order table:

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "root", "", "recycle");

// 查询用户的订单列表
$query = "SELECT * FROM orders WHERE user_name = '用户名'";
$result = mysqli_query($conn, $query);

// 展示订单列表
while ($row = mysqli_fetch_assoc($result)) {
    echo "<tr>";
    echo "<td>" . $row['id'] . "</td>";
    echo "<td>" . $row['product_id'] . "</td>";
    echo "<td>" . $row['user_name'] . "</td>";
    echo "<td>" . $row['email'] . "</td>";
    echo "<td>" . $row['address'] . "</td>";
    echo "<td>" . $row['order_type'] . "</td>";
    echo "<td>" . $row['create_time'] . "</td>";
    echo "</tr>";
}
?>

After the user selects the order to be returned/exchanged, we can query the product table according to the product ID of the order to obtain the detailed information of the product, and displayed to the user. At the same time, we need to provide a form for users to fill in the reasons and requirements for return/exchange:

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "root", "", "recycle");

// 获取选择的订单ID
$order_id = $_GET['order_id'];

// 查询订单信息
$query = "SELECT * FROM orders WHERE id = $order_id";
$result = mysqli_query($conn, $query);
$row = mysqli_fetch_assoc($result);

// 查询产品信息
$product_id = $row['product_id'];
$query = "SELECT * FROM products WHERE id = $product_id";
$result = mysqli_query($conn, $query);
$product = mysqli_fetch_assoc($result);

// 展示产品信息
echo "<h2>" . $product['name'] . "</h2>";
echo "<p>" . $product['description'] . "</p>";
echo "<p>价格：" . $product['price'] . "</p>";
echo "<img src='" . $product['image'] . "' alt='产品图片'>";

// 展示退货/换货表单
echo "<form action='handle_return.php' method='post'>";
echo "<input type='hidden' name='order_id' value='" . $order_id . "'>";
echo "<textarea name='reason' placeholder='请填写退货/换货原因和要求'></textarea>";
echo "<input type='submit' value='提交'>";
echo "</form>";
?>

Finally, we need to write code to handle return/exchange requests. Update the order type in the order table according to the order ID, and save the reasons and requirements for returns/exchanges to the order table:

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "root", "", "recycle");

// 获取退货/换货请求的订单ID和原因
$order_id = $_POST['order_id'];
$reason = $_POST['reason'];

// 更新订单表中的订单类型为退货/换货
$query = "UPDATE orders SET order_type = 2 WHERE id = $order_id";
mysqli_query($conn, $query);

// 将退货/换货的原因和要求保存到订单表中
$query = "UPDATE orders SET reason = '$reason' WHERE id = $order_id";
mysqli_query($conn, $query);

// 提示退货/换货请求成功
echo "退货/换货请求已提交，我们会尽快处理。";
?>

Through the above code, we have implemented a function that supports returns/exchanges Second hand recycling website. Users can browse the order list, select the order to return/exchange, and submit a return/exchange request. Administrators can handle returns/exchanges upon request and provide timely feedback to users.

To sum up, using PHP to develop a second-hand recycling website and adding return/exchange functions can provide users with a better shopping experience and also improve the service quality of the website. I hope the code examples in this article can help developers develop better second-hand recycling websites.
