Comment-System-Using-PHP-and-MySQLi

This simple repo shows how to create a comment system using Object Oriented method of PHP and MySQLi. Basically the User Comments are stored in a database. Each comment box has an edit and delete button whereby the user can update his/her comments. The User has to LogIn before updating comments

Creating the MySQL Database

Create database "CommentTut" and create tables "comments" on your localhost:

CREATE TABLE `comments` (
  `id` char(23) NOT NULL,
  `date` varchar(100) NOT NULL DEFAULT '',
  `message` varchar(100) NOT NULL DEFAULT '',
  PRIMARY KEY (`id`),
  UNIQUE KEY `date_UNIQUE` (`date`),
  UNIQUE KEY `message_UNIQUE` (`message`)
) 

ENGINE=InnoDB DEFAULT CHARSET=utf8;

Setup the db.php file

<?php
	$servername = "localhost";
	$username = "root";
	$password = "";
	$database = "CommentTut";

	$db = new mysqli($servername, $username, $password, $database);

	if(!$db){
		//Error Message
		die("Connection failed: " . $db->connect_error);
	}
