The online voting system project includes the following security measures:
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.
