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.
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.
<?php
$file_name = 'guestbook.txt';
if(!file_exists($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'])){
$username=check_input($_POST['username']);
$message=check_input($_POST['message']);
add_entry($username, $message, $file_name);
}
$final_content = file_get_contents($file_name);
?>

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.
