내가 이것을 테스트하기 위해 PHP로 기계에 아니지만, 당신이 querie이 로 다음과 변수들 ...

"select id from votes where username = '$user' and article_id = $this->id" 

나는 많은 있다는 ...

"select id from votes where username = '$user' and article_id = ${this->id}" 

또는

"select id from votes where username = '$user' and article_id = " . $this->id
