For at bruge PDO

        $query = "INSERT INTO `event` (`date`, `name`, `signup_start`, `signup_end`) VALUES (:date, :name, :signup_start, :signup_end)";


        $sql = $pdo->prepare($query);


        $sql->bindParam(':date', $this->date->format("Y-m-d"));

        $sql->bindParam(':name', $this->name);

        $sql->bindParam(':signup_start', $this->signup_start->format("Y-m-d H:i:s"));

        $sql->bindParam(':signup_end', $this->signup_end->format("Y-m-d H:i:s"));


        $sql->execute();


        if ($sql->errorCode() != "00000") {

            throw new Exception("[" . $sql->errorCode() . "]" . " " . $sql->errorInfo());

        } else {


            $last_insert_id = $pdo->lastInsertId();


            return true;


        }
