Online Voting System - Complete Project

Introduction to the Project

The Online Voting System is a secure, web-based application that allows organizations, institutions, or communities to conduct elections digitally. This system provides a platform where administrators can create and manage elections, define candidates, and monitor voting processes, while registered voters can cast their votes securely from anywhere with internet access.

The system implements role-based access control with three distinct user types: Admin, Voters, and Candidates. It ensures one person-one vote through database constraints, provides real-time result tabulation, and maintains voting integrity through session management and secure authentication.

Key Features

Admin Features

Dashboard Overview: View total voters, candidates, elections, and voting statistics
Election Management: Create, activate, deactivate, and delete elections
Candidate Management: Add, edit, and remove candidates for specific elections
Voter Management: View all registered voters and approve/block voter accounts
Result Management: Declare results and view detailed voting analytics
System Controls: Start/stop voting periods, ensure fair elections

Voter Features

User Registration: Register with personal details and unique voter ID
Secure Login: Access the system with credentials
View Elections: See active and upcoming elections
Cast Vote: Vote only once per election (system prevents duplicate voting)
View Results: See election results after declaration
Profile Management: Update personal information

Candidate Features

Candidate Dashboard: View election status and personal vote count
Profile Visibility: Display candidacy information to voters
Campaign Statement: Add personal message to voters

Technology Stack

Frontend: HTML5, CSS3, JavaScript (Vanilla)
Backend: PHP (Core PHP, no frameworks)
Database: MySQL
Server: Apache (XAMPP/WAMP/MAMP recommended)
