A well-designed database is critical. Below is a simplified schema:
They made sure a voter could only vote once per election using a UNIQUE constraint in the votes table.
// vote.php if ($row['has_voted'] == 1) die("You have already voted in this election.");
$stmt = $conn->prepare("INSERT INTO votes (voter_id, candidate_id, election_id) VALUES (?, ?, ?)"); $stmt->bind_param("sii", $voter_id, $candidate_id, $election_id); if ($stmt->execute()) // Update voters table $conn->query("UPDATE voters SET has_voted = 1 WHERE voter_id = '$voter_id'"); echo "Vote cast successfully!";
The PHP and MySQL-based Online Voting System successfully demonstrates how open-source technologies can digitize the electoral process securely and efficiently. The complete source code is available for download and contribution on GitHub: https://github.com/yourusername/online-voting-system-php. Future improvements may include adding two-factor authentication, blockchain-based vote logging for tamper-proof records, and SMS or email verification for voter identity.
By sharing this project on GitHub, I hope to provide a foundation for students and developers to learn full-stack web development while contributing to more transparent and accessible digital democracy tools.
Note: Replace https://github.com/yourusername/online-voting-system-php with your actual GitHub repository URL if you have one. If you need a ready-made source code example, I can also guide you to existing open-source projects on GitHub.

);
CREATE TABLE candidates (
id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(255),
description TEXT
);
CREATE TABLE votes (
id INT PRIMARY KEY AUTO_INCREMENT,
user_id INT,
candidate_id INT,
FOREIGN KEY (user_id) REFERENCES users(id),
FOREIGN KEY (candidate_id) REFERENCES candidates(id)
);
PHP Code
The PHP code for the online voting system project consists of the following files:
Here is a sample code snippet for the vote.php file:
<?php
include 'config.php';
if (isset($_POST['vote']))
$user_id = $_SESSION['user_id'];
$candidate_id = $_POST['candidate_id'];
$query = "INSERT INTO votes (user_id, candidate_id) VALUES ('$user_id', '$candidate_id')";
mysqli_query($conn, $query);
header("Location: results.php");
exit;
?>
