Online Discussion Forum Site in PHP/OOP Free Source Code



This simple project is entitled Online Discussion Forum Site. This is a web-based application project developed in PHP and MySQL Database. This simple project's main goal is to provide an online platform for an organization where they can discuss any topic that is related to the site or organization. The site allows users to post any topic under a certain topic category. Users can post comments on each posted published topic. The system user interface was developed with Bootstrap Framework and AdminLTE Framework. It also consists of user-friendly features and functionalities.

About the Online Discussion Forum Site

I developed this project using the following:

  • XAMPP v3.3.0
  • PHP
  • MySQL Database
  • HTML
  • CSS
  • JavaScript
  • Ajax
  • jQuery
  • Bootstrap
  • Font Awesome
  • AdminLTE

This Online Discussion Forum Site is accessible to anyone and site management. As I mentioned at beginning of this article, the project allows users to post or published certain topics. Each published topic is visible to the public and registered users. The system requires the users to register and log in with their credentials to gain access to posting topics and comments. This project also contains an Admin Panel Site where the site management can manage all the data on the system. This side of the project requires an administrator user credential to gain access to the features and functionalities. On this site, the management can overwrite, and delete users' posts and comments. The admin users also can create a new topic on this site. The Admin Users are the ones who are in charge of populating the topic category list. They can also update the system name, logo, etc.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. After downloading it, you will need a program like Winzip to decompress it.

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
