Online Voting System Project In Php


Creating an Online Voting System involves several components, including a MySQL database schema, file structure, layout design using Bootstrap 5, and complete PHP scripts for user authentication and management. Below is a comprehensive guide to help you set up your system.

Project Introduction

The Online Voting System is designed to provide a secure and efficient platform for conducting elections and managing voter participation. This system allows users to register as voters, create and manage elections, and cast their votes for candidates. With a robust MySQL database backend, the platform ensures secure data management, prevents double voting, and provides a user-friendly experience for all roles, including voters, administrators, and election officers.

Project Objectives

  • To create a secure registration and login system for voters and election officials.
  • To enable voters to create and manage their profiles, including contact information and voting preferences.
  • To facilitate the creation and management of elections, including setting start and end dates.
  • To allow candidates to submit their manifestos and campaign details for each election.
  • To implement a secure voting mechanism that prevents double voting and ensures the integrity of the election process.
  • To provide notifications to users regarding election updates, voting reminders, and results.
  • To offer an administrative dashboard for managing users, elections, and monitoring voting activities.

Project Modules

  1. User Management: Handles user registration, login, and role-based access for voters, admins, and election officers.
  2. Voter Profile Management: Allows voters to create and update their profiles, including personal information and preferences.
  3. Election Management: Enables the creation, updating, and management of elections, including setting criteria and dates.
  4. Candidate Management: Allows candidates to submit their manifestos and campaign details for elections.
  5. Voting System: Manages the voting process, ensuring secure and anonymous voting while preventing double voting.
  6. Notification System: Sends notifications to users about election updates, voting reminders, and results.
  7. Admin Dashboard: Provides administrative tools for managing users, elections, candidates, and monitoring voting activities.

    FOREIGN KEY (election_id) REFERENCES elections(id) ON DELETE CASCADE,
    FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
);
-- Table for votes
CREATE TABLE votes (

    FOREIGN KEY (voter_id) REFERENCES users(id) ON DELETE CASCADE,
    FOREIGN KEY (candidate_id) REFERENCES candidates(id) ON DELETE CASCADE,
    UNIQUE (election_id, voter_id) -- Prevent double voting
);
-- Table for notifications
CREATE TABLE notifications (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id `INT` NOT NULL,
    message VARCHAR(255) NOT NULL,
    is_read TINYINT(1) DEFAULT FALSE,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
