Title: A second-hand recycling website developed using PHP to support one-click quick purchase

Introduction: With the development of social economy and the improvement of living standards, people are paying more and more attention to environmental protection and sustainability. . The concept of second-hand recycling also emerged, providing people with a sustainable way to use resources. In order to facilitate people to buy and sell second-hand items, we can use PHP to develop a second-hand recycling website and provide convenient services through the one-click quick purchase function.

1. Website construction

First, we need to build a simple website. You can use a PHP framework such as Laravel, or write simple PHP code yourself. The process of building a website is beyond the scope of this article. We will focus on the function of realizing one-click quick purchase.

2. Database design

Before building the website, we need to design a database to store user information, product information and transaction records. The following is a simple example:

• User table (user): stores user registration information, such as user name, password, email, etc.

  CREATE TABLE user (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(255) NOT NULL,
    password VARCHAR(255) NOT NULL,
    email VARCHAR(255) NOT NULL,
    ...
  );

• Product table (product): stores product information, such as name, description, price, etc.

  CREATE TABLE product (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    description TEXT NOT NULL,
    price DECIMAL(10, 2) NOT NULL,
    ...
  );

• Order table (order): stores user purchase records and associates user tables and product tables.

  CREATE TABLE order (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT NOT NULL,
    product_id INT NOT NULL,
    datetime DATETIME NOT NULL,
    FOREIGN KEY (user_id) REFERENCES user(id),
    FOREIGN KEY (product_id) REFERENCES product(id),
  );

3. One-click quick purchase function implementation

The one-click quick purchase function is designed to allow users to click a button after selecting the product. The function of automatic order placement can be realized. The following is a simple code example:

// 商品详情页
$product_id = $_GET['product_id']; // 从url中获取商品id
$user_id = $_SESSION['user_id']; // 从session中获取用户id

// 查询商品信息
$query = "SELECT * FROM product WHERE id = $product_id";
$product = $db->query($query)->fetch_assoc();

// 提交订单
$query = "INSERT INTO order (user_id, product_id, datetime) VALUES ($user_id, $product_id, NOW())";
$db->query($query);

// 页面跳转到订单详情页
header("Location: order.php?id=".$db->insert_id);
exit;

In the above code, we first obtain the product id and user id, then query the product information, and insert the user id, product id, and current time into the order table. Finally, jump to the order details page.

4. Other function extensions

Based on the above implementation, we can add other functions, such as delivery address management, shopping cart function, etc., to provide better user experience. You can use PHP's related libraries and frameworks to implement these functions, such as Laravel's Eloquent ORM for database operations, or use the Smarty template engine to render pages.

Conclusion: The second-hand recycling website developed using PHP can provide users with convenient second-hand item transaction services through the one-click quick purchase function. Through reasonable database design and simple PHP code implementation, we can create a fully functional and user-friendly second-hand recycling platform to promote sustainable development and environmental protection.
