How to use PHP and CGI to implement the event calendar function of the website

With the development of the Internet, the functions of the website are becoming more and more abundant. A common feature is the event calendar, which can help users better organize their time and understand important events and activities. In this article, we will introduce how to use PHP and CGI to implement the event calendar function of the website.

Create database

First, we need to create a database to store event information. We can use MySQL to create a database called "events". In this database, we need to create a table called "event" that will store information such as the title, date, and description of the event.

The following is the SQL statement to create the "event" table:

CREATE TABLE IF NOT EXISTS event (
    id INT(11) PRIMARY KEY AUTO_INCREMENT,
    title VARCHAR(255),
    date DATE,
    description TEXT
);

Create a web form

Next, we need to create a web form, using Used to allow the user to enter event information. We can use HTML and CSS to create a simple form as shown below:

<!DOCTYPE html>
<html>
<head>
    <title>添加事件</title>
    <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
    <h1>添加事件</h1>
    <form action="add_event.php" method="post">
        <label for="title">标题:</label>
        <input type="text" id="title" name="title" required>

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

        <label for="description">描述:</label>
        <textarea id="description" name="description" required></textarea>

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

Handling form submission

In the previous step, we created a form, When the user submits the form, we need to use PHP to process the form's data and add the data to the database.

We can create a PHP file named "add_event.php" to handle form submission. Here is a code example for "add_event.php":

<?php
// 连接到数据库
$mysqli = new mysqli("localhost", "username", "password", "events");

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

// 获取用户提交的数据
$title = $_POST['title'];
$date = $_POST['date'];
$description = $_POST['description'];

// 预处理SQL语句
$stmt = $mysqli->prepare("INSERT INTO event (title, date, description) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $title, $date, $description);

// 执行SQL语句
if ($stmt->execute()) {
    echo "事件添加成功!";
} else {
    echo "事件添加失败: " . $stmt->error;
}

// 关闭连接
$stmt->close();
$mysqli->close();
?>

Display event calendar

Finally, we need to create a page to display the event calendar. We can use PHP to read event information from the database and display it in the form of a calendar.

The following is a simple code example for displaying an event calendar:

<?php
// 连接到数据库
$mysqli = new mysqli("localhost", "username", "password", "events");

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

// 查询数据库，获取事件的信息
$result = $mysqli->query("SELECT title, date, description FROM event");

// 显示事件日历
echo "<h1>事件日历</h1>";

while ($row = $result->fetch_assoc()) {
    echo "<h3>{$row['date']}</h3>";
    echo "<p>{$row['title']}</p>";
    echo "<p>{$row['description']}</p>";
}

// 关闭连接
$result->free();
$mysqli->close();
?>

Copy after login

Through the above steps, we can implement a simple event calendar function on the website. Users can add new events through the add event form and view all events on the events calendar page.

Summary:

By using PHP and CGI, we can easily implement the event calendar function of the website. We first need to create a database to store event information, and then create a web form to allow users to enter event information. Next, we use PHP to handle form submission and add the data to the database. Finally, we use PHP to read the event information from the database and display it on the event calendar page. With these steps, we can provide users with a functional calendar of events on our website.
