Create Guestbook in PHP


Guestbook is not mandatory for site but if you want to have a guestbook where visitor of your site leaves message publicly then this post is for you. Guestbook is a better way to show your site's fame. If a guest appreciate your product on site through contact us form then just you will know but If a visitor publicly posted on guestbook then everyone will know your service or product's fame.

Guestbook Example

Most of guestbook script available on internet is based on PHP and Mysql. That is little lengthy process where you have to setup database and tables. But today I will show you how to create guestbook without MYSQL.  

$file_name = 'guestbook.txt';
if(!file_exists($file_name)) {
        file_put_contents($file_name, '');
function check_input($input){
    if(empty(trim($input))) {
        die('Fill all fields properly');
    } else {
        return htmlspecialchars($input);
function add_entry($username, $message, $file_name) {
    $get_content = file_get_contents($file_name);
    $time = date('Y-m-d h:i A',time());
    $content = '<div class="container border rounded p-3 bg-light"><b>'.$username.'</b><span class="text-muted"> ('.$time.')</span>'.'<p class="text-dark">'.$message."</p></div>\n".$get_content;
    file_put_contents($file_name, $content);
if(isset($_POST['username']) && isset($_POST['message'])){
    add_entry($username, $message, $file_name);
$final_content = file_get_contents($file_name);

    <button class="btn btn-success" data-toggle="modal" data-target="#addMessage">Add New Message</button>
    <div class="row mt-2">
        <div class="col-md-6 offset-md-3 col-sm-12">
            echo $final_content;
<div class="modal fade" id="addMessage" role="dialog">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h3>Leave a Message</h3>
            <div class="modal-body">
                <div class="container border rounded bg-light p-2">
                    <form action="" method="post" class="form">
                        <input type="text" class="form-control mb-1" name="username" placeholder="Full Name(eg. John Doe)" required="">
                        <textarea name="message" id="" cols="10" rows="5" class="form-control" placeholder="Leave your message...." required=""></textarea>
                        <input type="submit" class="btn btn-danger mt-1" value="Submit">

Note: It will create a new file named guestbook.txt on the folder it is uploaded to and store all the guestbook messages. If you deleted guestbook.txt all data will be lost.

Thanks for reading...

Hello, I do believe your site could possibly be having web browser compatibility problems. When I look at your website in Safari, it looks fine however, when opening in IE, it's got some overlapping issues. I merely wanted to provide you with a quick heads up! Besides that, wonderful site!

Currently it seems like Wordpress is the best blogging platform out there right now. (from what I've read) Is that what you're using on your blog?

Nice post. I learn something new and challenging on sites I stumbleupon everyday. It will always be helpful to read through articles from other authors and practice something from other sites.


What's up, after reading this awesome post i am too glad to share my knowledge here with mates.

My programmer is trying to persuade me to move to .net from PHP. I have always disliked the idea because of the costs. But he's tryiong none the less. I've been using WordPress on a number of websites for about a year and am anxious about switching to another platform. I have heard fantastic things about blogengine.net. Is there a way I can transfer all my wordpress content into it? Any kind of help would be greatly appreciated!
