PHP Development Guide: How to Implement Online Booking Function

In today's digital era, more and more enterprises and service providers hope to provide online booking services to their customers. Booking feature. Whether it is hotel booking, flight booking or other service booking, developing a reliable online booking system is crucial for modern businesses. This article will introduce you to how to use PHP to develop online booking functions and provide some code examples.

1. Database design

First, we need to design a database to store reservation information. The following is a simple database table structure example:

CREATE TABLE `bookings` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(100) NOT NULL,
  `email` varchar(100) NOT NULL,
  `date` date NOT NULL,
  `time` time NOT NULL,
  PRIMARY KEY (`id`)
);

2. Create a reservation form

Create an HTML form for users to enter reservation information. The following is a simple form example:

<form method="post" action="booking.php">
  <input type="text" name="name" placeholder="姓名" required>
  <input type="email" name="email" placeholder="邮箱" required>
  <input type="date" name="date" required>
  <input type="time" name="time" required>
  <input type="submit" value="预订">
</form>

3. Handling booking requests

Create a PHP file named booking.php to handle the user's booking request. The following is a simple processing example:

<?php
// 连接数据库
$conn = new mysqli("localhost", "username", "password", "database");

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

// 获取表单提交的数据
$name = $_POST['name'];
$email = $_POST['email'];
$date = $_POST['date'];
$time = $_POST['time'];

// 插入数据到数据库
$sql = "INSERT INTO bookings (name, email, date, time) VALUES ('$name', '$email', '$date', '$time')";

if ($conn->query($sql) === TRUE) {
  echo "预订成功！";
} else {
  echo "预订失败: " . $conn->error;
}

// 关闭数据库连接
$conn->close();
?>

4. Display booking information

If you wish to display the user's booking information, you can query the database and display the results in on the web page. Here is an example of a simple query and displayed results:

<?php
// 连接数据库...

// 查询数据库
$sql = "SELECT * FROM bookings";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  // 输出每一行数据
  while($row = $result->fetch_assoc()) {
    echo "姓名: " . $row["name"]. " - 邮箱: " . $row["email"]. " - 日期: " . $row["date"]. " - 时间: " . $row["time"]. "<br>";
  }
} else {
  echo "暂无预订信息";
}

// 关闭数据库连接...
?>

With the above steps, you can create a simple online booking system. Of course, this is just a basic example, and you can extend and optimize the function according to actual needs.
