The second-hand recycling website developed using PHP supports multiple payment methods

With the progress of society and the improvement of environmental awareness, second-hand recycling has become an important way of life. In order to meet people's needs, it is crucial to develop a second-hand recycling website that supports multiple payment methods. In this article, we will develop such a website using PHP and give relevant code examples.

1. Build a website framework

First, we need to build a basic website framework. We can use popular PHP frameworks like Laravel, CodeIgniter or Symfony. Choose a framework that suits your needs and experience, and follow the framework's documentation to set it up.

2. Database design

Next, we need to design a database to store our user and product information. We can use MySQL or other relational database. Here is an example of a simple user table and product table:

CREATE TABLE users (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(50) NOT NULL,
  email VARCHAR(100) NOT NULL,
  password VARCHAR(100) NOT NULL
);

CREATE TABLE items (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(100) NOT NULL,
  description TEXT,
  price DECIMAL(10, 2) NOT NULL,
  user_id INT,
  FOREIGN KEY (user_id) REFERENCES users(id)
);

3. User Registration and Login

On a website, users need to be able to register and log in. The following is a sample code for a registration and login page:

Registration page (register.php):

<form action="register.php" method="POST">
  <input type="text" name="name" placeholder="姓名" required>
  <input type="email" name="email" placeholder="邮箱" required>
  <input type="password" name="password" placeholder="密码" required>
  <button type="submit">注册</button>
</form>

Login page (login.php):

<form action="login.php" method="POST">
  <input type="email" name="email" placeholder="邮箱" required>
  <input type="password" name="password" placeholder="密码" required>
  <button type="submit">登录</button>
</form>

When the user submits When registering and logging in forms, we can use PHP to handle user input and add data to the database or validate user information.

4. Product release and payment function

Our second-hand recycling website needs to have a page to display the currently released products and a page for releasing products. Users can Fill in the product information here and select the payment method.

Product display page (show_items.php):

<?php
  // 查询数据库中的商品信息
  $items = DB::table('items')->get();

  foreach ($items as $item) {
    echo $item->name . ' - ￥' . $item->price;
    echo '<a href="buy_item.php?id=' . $item->id . '">购买</a>';
    echo '<br>';
  }
?>

Publish product page (create_item.php):

<form action="create_item.php" method="POST">
  <input type="text" name="name" placeholder="商品名称" required>
  <textarea name="description" placeholder="商品描述" required></textarea>
  <input type="number" name="price" placeholder="商品价格" required>
  <select name="payment_method">
    <option value="alipay">支付宝</option>
    <option value="wechatpay">微信支付</option>
    <option value="bank">银行转账</option>
  </select>
  <button type="submit">发布商品</button>
</form>

When the user submits the product release form, we can use PHP to process user input and store product information in the database.

Buy item page (buy_item.php):

<?php
  $itemId = $_GET['id'];
  $item = DB::table('items')->where('id', $itemId)->first();
?>

商品名称：<?php echo $item->name; ?><br>
商品价格：￥<?php echo $item->price; ?><br>
选择支付方式：<br>
<form action="pay.php" method="POST">
  <input type="hidden" name="item_id" value="<?php echo $itemId; ?>">
  <select name="payment_method">
    <option value="alipay">支付宝</option>
    <option value="wechatpay">微信支付</option>
    <option value="bank">银行转账</option>
  </select>
  <button type="submit">立即支付</button>
</form>

When the user selects the payment method and submits the payment form, we can use PHP to process the user input and make the payment according to the selected payment method .

Payment processing page (pay.php):

<?php
  $itemId = $_POST['item_id'];
  $paymentMethod = $_POST['payment_method'];

  // 根据选择的支付方式进行支付处理

  echo '支付成功！';
?>

In this example, we simply demonstrate how to use PHP to develop a second-hand recycling website that supports multiple payment methods. Depending on actual needs, you may need to continue to develop other functions, such as order management, payment interface integration, etc.

I hope this article can help you understand how to use PHP to develop a second-hand recycling website that supports multiple payment methods. Good luck with your development!
