Online Voting System

Online Voting System Using PHP & MySQL

The Online Voting System is a web-based application developed using PHP, MySQL, HTML, CSS and JavaScript. It is designed to provide a simple digital platform for conducting elections and voting activities within colleges, organizations, institutions and other small groups.

The system provides separate functionality for administrators and voters. Administrators can manage candidates, registered voters and voting results, while verified voters can participate in the election and cast their vote through the online voting interface.

The project also includes OTP-based voter verification to add an additional verification step before accessing the voting process. The system maintains voting records and prevents a registered voter from submitting multiple votes.

Voter Module

The voter module allows registered users to complete the verification process and participate in an election.

• Voter Registration
• Enter Personal Details
• Mobile Number Verification
• OTP Verification
• Voter Login

OTP Verification

The system can use OTP verification as an additional authentication layer during voter registration. After entering the required details, the voter verifies their registered mobile number using the OTP provided by the configured OTP service.

OTP verification helps ensure that the voter account is verified before accessing the voting process.

Candidate Management

Administrators can manage the candidates participating in an election. Candidate information can be added and maintained through the administration panel.

• Add Candidate
• Candidate Details
• Edit Candidate
• Delete Candidate
• View Candidate List

Online Voting Module

After successful registration and verification, eligible voters can access the voting interface and select their preferred candidate. The system records the submitted vote in the database.

• Verified Voter Access
• Candidate Selection
• Vote Submission
• Vote Status Tracking
• Duplicate Vote Prevention

Voting Results

The system automatically maintains vote counts based on submitted voting records. Administrators can access the results section to view candidate-wise voting statistics and the overall election outcome.

• Candidate-wise Vote Count
• Total Votes
• Voting Statistics
• Election Results
• Result Management

Technologies Used

• Frontend: HTML5, CSS3, JavaScript
• Backend: PHP
• Database: MySQL
• Server: Apache / XAMPP
• OTP: Configured OTP/API Service

Database

MySQL is used to store voter information, candidate records, authentication details and voting-related data. The database provides the backend storage required for managing the election process.

Installation Guide

1. Download and extract the project ZIP file.
2. Copy the project folder into the XAMPP htdocs directory.
3. Start Apache and MySQL from the XAMPP Control Panel.
4. Open phpMyAdmin in your browser.
5. Create a new database for the voting system.
6. Import the provided SQL database file.
7. Open the database configuration file.
8. Update the database name, username and password according to your MySQL configuration.
9. Configure the OTP/API credentials if OTP verification is enabled.
10. Open the project folder in Visual Studio Code.
11. Run the project through XAMPP localhost.
12. Open the project URL in your browser.
13. Login using the provided Admin credentials.

System Requirements

• Windows / Linux / macOS
• XAMPP
• Apache Server
• PHP

Who Can Use This Project?

This project is suitable for BCA, MCA, B.Tech, M.Tech and other computer science students looking for a practical PHP and MySQL project. It can be used for learning web development, database management, authentication, voting workflows and backend programming.

The system can also serve as a base application for internal elections in colleges, organizations, clubs, societies and other small groups where a customized voting solution is required.

Conclusion

The Online Voting System provides a structured web-based platform for managing voters, candidates and election results. With PHP and MySQL as its core technologies, along with voter verification and duplicate-vote prevention, the project demonstrates how a traditional voting workflow can be implemented as a web application.

This project is intended as an educational and customizable software solution and should not be treated as certified software for public or governmental elections.
