Incentive Voting

Rune-Nexus utilizes a callback feature that will send a GET request to the callback url you specify when adding your server. It is a string, usually an IP Address, username, or randomly generated string. This string comes from your voting script which is appended at the end of the vote url.

Example Callback

For developer use. If you're just setting up your server, this is not relevant.

Your voting script should have a callback feature already built in. If you need it, here's some example php code to handle callbacks. This will most likely not work for any toplist, but the principal is there :)

                                <?php
                                    $log_file = "callbacks.log";

                                    $db_host = 'localhost';
                                    $db_name = 'voting';
                                    $db_user = 'root';
                                    $db_pass = 'password';

                                    if (isset($_POST['callback']) && !empty($_POST['callback']) {
                                        $callback = filter_var($_POST['callback'], FILTER_SANITIZE_STRING);

                                        #Connect to database
                                        try {
                                            $pdo = new PDO("mysql:host=" . $db_host . ";dbname=" . $db_name, $db_user, $db_pass);
                                            $pdo->exec("SET CHARACTER SET utf8");

                                        }

                                        # prepare query for execution

                                        $count = $stmt->rowCount(); # counts modified rows

                                        # counts modified rows. if 0, then nothing was changed, Log it to log file.
                                        if ($stmt->rowCount() > 0) {
                                            error_log(date('[Y-m-d H:i] ')."[Error] Update query failed! ".PHP_EOL, 3, $log_file);
