The second-hand recycling website uses the online reservation service function developed by PHP

Introduction:
With the rapid development of society and the increasing scarcity of resources, second-hand recycling has become an important environmental awareness and resource recycling method of utilization. In order to meet the needs of users and improve user experience, many second-hand recycling websites have begun to introduce online appointment service functions. This article will introduce how to use PHP to develop the reservation service function of a simple second-hand recycling website.

Development environment preparation:

A server with PHP installed;
A database that supports MySQL;
A text editor.

Database design:
Before you start writing code, you first need to design the database. We need to create two tables, one to store user information and the other to store reservation information.

User table (user_table):
Fields: id, name, phone, address

Appointment table (appointment_table):
Fields: id, user_id, date, time, remark

Code implementation:

Create database connection:

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
?>

Copy after login

Create reservation function page:

<!DOCTYPE html>
<html>
<head>
    <title>二手回收预约</title>
</head>
<body>
    <h1>预约二手回收</h1>
    <form method="post" action="submit.php">
        <label for="name">姓名：</label>
        <input type="text" name="name" required><br>

        <label for="phone">电话：</label>
        <input type="text" name="phone" required><br>

        <label for="address">地址：</label>
        <input type="text" name="address" required><br>

        <label for="date">日期：</label>
        <input type="text" name="date" required><br>

        <label for="time">时间：</label>
        <input type="text" name="time" required><br>

        <label for="remark">备注：</label>
        <textarea name="remark"></textarea><br>

        <input type="submit" value="提交">
    </form>
</body>
</html>

Copy after login

Processing appointment submission requests:

<?php
include 'db_connect.php'; // 连接数据库

$name = $_POST['name'];
$phone = $_POST['phone'];
$address = $_POST['address'];
$date = $_POST['date'];
$time = $_POST['time'];
$remark = $_POST['remark'];

// 插入预约信息
$sql = "INSERT INTO appointment_table (user_id, date, time, remark)
VALUES ('$name', '$phone', '$address', '$date', '$time', '$remark')";

if ($conn->query($sql) === TRUE) {
    echo "预约成功！";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>

Copy after login

Summary:
Through the above code example, we can see how to use PHP to develop the appointment service function of a simple second-hand recycling website. Users can fill in the reservation form through the website, and the server saves the reservation information submitted by the user into the database. In this way, both users and website administrators can easily manage and process appointment requests, improving user experience and website operation efficiency. The introduction of this function not only improves the service quality of second-hand recycling websites, but also further promotes the popularization of environmental awareness and recycling of resources.
