The second-hand recycling website uses the product release and review function developed by PHP

With the rapid development of the second-hand commodity trading market, the second-hand recycling website has become the first choice platform for users to deal with idle items. However, in order to ensure the security and quality of transactions, the website needs to implement a product release review function. This article will introduce how to use PHP to develop the product release review function of a second-hand recycling website, and provide some code examples for reference.

Requirements Analysis
Before implementing the product release review function, you first need to clarify the requirements. Generally speaking, the product release review function should have the following functions:

After the user releases the product, the administrator needs to review and confirm whether it meets the transaction standards stipulated by the website;
Administrators can review, pass or reject the published products, and give corresponding feedback information;
Users can check whether the products they published have passed the review, and view the administrator's review opinions .

Database design
In order to realize the product release review function, it is necessary to design the corresponding database table. The following is the design of the sample table:

users table: stores user information, including user ID, user name, password, etc.
products table: stores product information, including product ID, title, description, price, etc.
product_review table: stores product review information, including review ID, product ID, review status (pass/reject), review opinions, etc.

Page development
First, we need to design the page for the administrator to review the product. After logging in, the administrator can view the list of products to be reviewed. Click on a product to view details and conduct review. The following is a simple page example:

<?php
// 待审核商品列表页面
session_start(); // 启动会话

// 检查管理员是否已登录，若未登录则跳转到登录页面
if (!isset($_SESSION['admin'])) {
    header("Location: login.php");
    exit();
}

// 查询待审核的商品列表
$query = "SELECT * FROM products WHERE status = 'pending'";
$result = mysqli_query($conn, $query);
?>

<!DOCTYPE html>
<html>
<head>
    <title>商品审核</title>
</head>
<body>
    <h1>待审核商品列表</h1>
    <table>
        <tr>
            <th>商品ID</th>
            <th>标题</th>
            <th>价格</th>
            <th>操作</th>
        </tr>
        <?php while ($row = mysqli_fetch_assoc($result)): ?>
            <tr>
                <td><?php echo $row['id']; ?></td>
                <td><?php echo $row['title']; ?></td>
                <td><?php echo $row['price']; ?></td>
                <td><a href="review.php?id=<?php echo $row['id']; ?>">审核</a></td>
            </tr>
        <?php endwhile; ?>
    </table>
</body>
</html>

When the administrator clicks the "review" link of a product, it will jump to the review page. The following is a sample code for the audit page:

<?php
// 审核具体商品页面
session_start(); // 启动会话

// 检查管理员是否已登录，若未登录则跳转到登录页面
if (!isset($_SESSION['admin'])) {
    header("Location: login.php");
    exit();
}

// 获取商品ID
$id = $_GET['id'];

// 查询商品信息
$query = "SELECT * FROM products WHERE id = $id";
$result = mysqli_query($conn, $query);
$row = mysqli_fetch_assoc($result);

// 提交审核结果
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $status = $_POST['status'];
    $feedback = $_POST['feedback'];
    
    // 更新商品审核信息
    $updateQuery = "UPDATE product_review SET status = '$status', feedback = '$feedback' WHERE product_id = $id";
    mysqli_query($conn, $updateQuery);
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>商品审核</title>
</head>
<body>
    <h1>审核商品</h1>
    <h2><?php echo $row['title']; ?></h2>
    <p><?php echo $row['description']; ?></p>
    <form method="POST">
        <input type="radio" name="status" value="approved"> 通过
        <input type="radio" name="status" value="rejected"> 拒绝
        <br>
        <textarea name="feedback" placeholder="审核意见"></textarea>
        <br>
        <input type="submit" value="提交">
    </form>
</body>
</html>

Database operation
In the audit page, the audit results need to be saved to the database. The following is a simple code example:

// 提交审核结果
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $status = $_POST['status'];
    $feedback = $_POST['feedback'];
    
    // 更新商品审核信息
    $updateQuery = "UPDATE product_review SET status = '$status', feedback = '$feedback' WHERE product_id = $id";
    mysqli_query($conn, $updateQuery);
}

The above example is just a simple demonstration, and the actual business logic and page design may be more complex. But through this example, we can understand how to use PHP to develop the product release review function of a second-hand recycling website. Hope this article helps you!
