The second-hand recycling website developed using PHP supports one-click publishing function

With the increasing awareness of environmental protection, second-hand recycling has become a way of life for people. In order to facilitate users to find items that can be reused and promote the development of environmental protection, it is very necessary to develop a second-hand recycling website. This article will introduce a second-hand recycling website developed using PHP and add a one-click publishing function.

First of all, we need to build a basic second-hand recycling website. The following is a simple code example:

// index.php

<!DOCTYPE html>
<html>
<head>
    <title>二手回收网站</title>
</head>
<body>
    <h1>欢迎来到二手回收网站</h1>
    <h2>物品列表</h2>
    <ul>
        <?php
        // 从数据库获取物品列表并展示
        $items = [
            ['id' => 1, 'name' => '电视', 'price' => 500],
            ['id' => 2, 'name' => '手机', 'price' => 800],
            ['id' => 3, 'name' => '电脑', 'price' => 1200]
        ];

        foreach ($items as $item) {
            echo '<li>' . $item['name'] . ' - ¥' . $item['price'] . '</li>';
        }
        ?>
    </ul>

    <h2>发布物品</h2>
    <form action="add_item.php" method="POST">
        <label for="name">物品名称:</label>
        <input type="text" name="name"><br>
        <label for="price">价格:</label>
        <input type="number" name="price"><br>
        <input type="submit" value="发布">
    </form>
</body>
</html>

In the above code, we use a static item list as an example and display it on the page through a foreach loop. Below is a form for publishing items. After the user fills in the information, clicking the publish button will submit the item information to add_item.php for processing.

Next, we need to write add_item.php to handle the adding function of items. The following is a simple code example:

// add_item.php

<?php
// 假设这里连接了数据库

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $name = $_POST['name'];
    $price = $_POST['price'];

    // 进行数据验证和处理
    // ...

    // 将物品信息保存到数据库
    $item = ['name' => $name, 'price' => $price];

    // 假设这里保存到数据库的操作
    // ...

    // 返回首页
    header('Location: index.php');
} else {
    // 如果不是POST请求，则跳转到首页
    header('Location: index.php');
}

In add_item.php, first determine whether the request method is POST. If it is a POST request, we get the name and price of the item from the $_POST array. Then carry out the process of data verification and processing (specifically based on actual needs). Finally, save the item information to the database and redirect the user to the home page through the header function.

By adding add_item.php, we have implemented the one-click publishing function. Users can fill in the item information on the homepage. After clicking the publish button, the item information will be saved to the database and quickly returned to the homepage for other users to browse.

To sum up, the second-hand recycling website we developed using PHP successfully supports the one-click publishing function. Users can easily publish their second-hand items, and other users can browse these items and reuse them, contributing to environmental protection. Of course, in actual development, we still need to consider more functions and security issues, but this article has given a simple solution to the implementation of one-click publishing function. I hope this article can be helpful to PHP developers.
