How to implement the website message board function through PHP and Typecho

With the continuous development of the Internet, the communication and interactive functions of the website are becoming more and more important. As an important part of user communication on the website, message boards have also become one of the indispensable functions of many websites. This article will introduce how to implement the website message board function through PHP and Typecho, a simple and easy-to-use blog program.

Typecho is an open source, lightweight and efficient blogging program with a flexible plug-in system and rich themes to choose from. Through Typecho, we can quickly build a fully functional blog website. The following are the steps to implement the website message board function through PHP and Typecho.

1. Download and install Typecho
   First, we need to download Typecho and install it on our web server. Typecho’s official website provides the latest download links and installation instructions. Follow the instructions to complete the installation process. After starting Typecho, we can start setting up the message board function.
2. Create message board page
   In Typecho’s background management interface, select “Page” and then click the “Create Page” button. Then fill in the page title and content and use the page to display the message board.
3. Create message board form
   On the message board page, we need to create an HTML form for users to enter message content. The following is a simple message board form example, which can be inserted into the page code in the edit mode of the page:

<form action="/path/to/message/action.php" method="post">
    <label for="name">姓名：</label>
    <input type="text" id="name" name="name" required>

    <label for="email">邮箱：</label>
    <input type="email" id="email" name="email" required>

    <label for="message">留言内容：</label>
    <textarea id="message" name="message" required></textarea>

    <button type="submit">提交</button>
</form>

In the code, we define a message submission form through the form element, and Specifies the processing address when submitting the form.

4. Processing message board form submission
   Next, we need to create a PHP script to handle message board form submission. In the Typecho installation directory, create a new PHP file named message_action.php. Then insert the following code into the file:

<?php
if($_SERVER['REQUEST_METHOD'] === 'POST'){
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];

    $db = Typecho_Db::get();
    $db->query($db->insert('table.comments')->rows([
        'cid' => 1,
        'name' => $name,
        'mail' => $email,
        'text' => $message,
        'created' => time(),
        'status' => 'approved',
        'type' => 'comment'
    ]));

    $referer = $_SERVER['HTTP_REFERER'];
    header("Location: $referer");
    exit;
}
?>

In the code, we first use $_POST to obtain the name, email address and message content entered by the user in the form. Then, we use the database operation interface provided by Typecho to insert the message information into Typecho's comment table. Finally, use the header function to redirect the page back to the message board page.

5. Display message board content
   Finally, we need to display the message content submitted by the user on the message board page. In the edit mode of the message board page, you can insert the following code snippet through the comment output function provided by Typecho:

<?php
$comments = $this->widget('Widget_Comments_Recent', 'ignoreAuthor=true')->to($comments);
while($comments->next()):
?>
    <div class="comment">
        <h3><?php $comments->author(false) ?></h3>
        <p><?php $comments->text() ?></p>
    </div>
<?php endwhile; ?>

In the above code, we use the Widget_Comments_Recent plug-in provided by Typecho to obtain the latest comments. Then output the author and content of each comment by looping through it.

Through the above steps, we have successfully implemented the website message board function using PHP and Typecho. Users can now fill in their name, email address and message content on the message board page and submit it to the server for processing. The server will save and display messages submitted by users and provide them to other users for review and reply.

This article introduces how to implement the website message board function through PHP and Typecho. By using the database operation interface and comment output function provided by Typecho, we can quickly implement a simple and complete message board function.
