Question

我正在构建一个小型Web应用程序，允许用户在MySQL数据库中编写反馈。这是负责编写反馈的功能：

public function add(Feedback $feedback) {
        $query = $this->db->prepare('INSERT INTO feedback SET country = :country, country-other = :countryOther, find-out = :findOut, find-out-other = :findOutOther, what-tour = :whatTour, booking-rating = :bookingRating, booking-comments = :bookingComments, checkin-rating = :checkinRating, checkin-comments = :checkinComments, journey-rating = :journeyRating, journey-comments = :journeyComments, guides-informative-rating = :guidesInformativeRating, guides-informative-comments = :guidesInformativeComments, guides-professional-rating = :guidesProfessionalRating, guides-professional-comments = :guidesProfessionalComments, tour-rating = :tourRating, tour-comments = :tourComments, tour-length = :tourLength, recommendation = :recommendation, comments = :comments');
        $query->bindValue(':country', $feedback->country());
        $query->bindValue(':countryOther', $feedback->countryOther());
        $query->bindValue(':findOut', $feedback->findOut());
        $query->bindValue(':findOutOther', $feedback->findOutOther());
        $query->bindValue(':whatTour', $feedback->whatTour());
        $query->bindValue(':bookingRating', $feedback->bookingRating());
        $query->bindValue(':bookingComments', $feedback->bookingComments());
        $query->bindValue(':checkinRating', $feedback->checkinRating());
        $query->bindValue(':checkinComments', $feedback->checkinComments());
        $query->bindValue(':journeyRating', $feedback->journeyRating());
        $query->bindValue(':journeyComments', $feedback->journeyComments());
        $query->bindValue(':guidesInformativeRating', $feedback->guidesInformativeRating());
        $query->bindValue(':guidesInformativeComments', $feedback->guidesInformativeComments());
        $query->bindValue(':guidesProfessionalRating', $feedback->guidesProfessionalRating());
        $query->bindValue(':guidesProfessionalComments', $feedback->guidesProfessionalComments());
        $query->bindValue(':tourRating', $feedback->tourRating());
        $query->bindValue(':tourComments', $feedback->tourComments());
        $query->bindValue(':tourLength', $feedback->tourLength());
        $query->bindValue(':recommendation', $feedback->recommendation());
        $query->bindValue(':comments', $feedback->comments());

        // $query = $this->db->prepare('INSERT INTO feedback (country) VALUES (:country)');
        // $country = $feedback->country();
        // echo $country;
        // $query->bindParam(':country', $country);
        $query->execute();
    }

注释行显示我做过的测试，看它是否在DB上写，但事实并非如此。

所以问题是我没有收到任何错误消息。我确信我已正确连接到数据库（同样的功能正在进行项目的第一次绘制，其中包括一个更简单的数据库）。

我检查了$ feedback对象包含所有正确的参数，确实如此。

那么我的错误是什么？谢谢你的帮助。

好的，我一定很傻。我通过更改所有＆＃39; - ＆＃39;来解决问题。在＆＃39; _＆＃39;在DB结构中。通常最简单的解决方案都有效。
