beginTransaction(); try // Double-check voting status inside transaction loop $stmt = $conn->prepare("SELECT voted FROM users WHERE id = ? FOR UPDATE"); $stmt->execute([$user_id]); if($stmt->fetch()['voted'] == 1) throw new Exception("Already voted."); // Process choices foreach($_POST as $key => $candidate_id) if(strpos($key, 'position_') !== false) // Extract position ID from input array name $position_id = filter_var($key, FILTER_SANITIZE_NUMBER_INT); $insert = $conn->prepare("INSERT INTO votes (position_id, candidate_id) VALUES (?, ?)"); $insert->execute([$position_id, $candidate_id]); // Lock the user from voting again $update = $conn->prepare("UPDATE users SET voted = 1 WHERE id = ?"); $update->execute([$user_id]); $conn->commit(); echo "Vote submitted successfully!"; catch (Exception $e) $conn->rollBack(); echo "Submission Error: " . $e->getMessage(); ?> Use code with caution. Enhancing System Portability
A clean, modular directory structure is vital for portability. It allows developers to download the GitHub repository and run the application instantly without altering complex path variables. // Mark voter as voted mysqli_query($conn
if($voter['has_voted'] == 0) // Update candidate votes mysqli_query($conn, "UPDATE candidates SET votes = votes + 1 WHERE id=$candidate_id"); // Mark voter as voted mysqli_query($conn, "UPDATE voters SET has_voted=1 WHERE voter_id='$voter_id'");
In today's digital age, online voting systems have become increasingly popular as they provide a convenient, secure, and transparent way to conduct elections. In this article, we will discuss an online voting system project in PHP and MySQL, including its features, source code, and GitHub repository. We will also provide a portable version of the project that can be easily deployed on any server.
