我将FOSFacebookBundle和FOSUserBundle与 Symfony2 一起使用来管理我的用户。我在本地一切正常。但是，当我将所有内容推送到我的暂存环境时，我注意到用户在注册时并没有持久化（使用原则实体管理器）。
我检查的第一件事是我是否可以使用实体管理器保留其他东西，这很好。接下来我继续检查日志，发现插入语句在那里：
INSERT INTO user (username, username_canonical, email, email_canonical, enabled, salt, password, last_login, locked, expired, expires_at, confirmation_token, password_requested_at, roles, credentials_expired, credentials_expire_at, firstname, lastname, facebookID, date_of_birth, locale, gender, has_profile_pic, created_at, updated_at)
VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
({"1":"1234","2":"1234","3":"foo@gmail.com","4":"foo@gmail.com","5":true,"6":"","7":"","8":null,"9":0,"10":false,"11":null,"12":null,"13":null,"14":["ROLE_FACEBOOK"],"15":0,"16":null,"17":"Mr","18":"Foo","19":"1234","20":{"date":"1986-12-09 00:00:00","timezone_type":3,"timezone":"PRC"},"21":"nl_NL","22":"male","23":1,"24":{"date":"2012-07-06 01:34:47","timezone_type":3,"timezone":"PRC"},"25":{"date":"2012-07-06 01:34:47","timezone_type":3,"timezone":"PRC"}})
当我用准备好的语句的值替换问号并手动发出查询时，一切正常。
有没有人知道这可能是什么？我也会很高兴得到有关如何进一步调试的提示，因为我不知道下一步该往哪里看..
提前致谢！
更新：
我又看了一眼 mysql 日志，我注意到 INSERT 语句正在准备中，但从未执行（与 select 语句不同）。我在错误日志中找不到任何错误。这是mysql日志：

有什么线索吗？
更新 2：
我一直在学说库中记录执行 PDO 语句的一些返回值，结果我在开发环境中得到了正常的返回值 (1)。但是，我在生产环境中没有得到任何返回值。似乎是另一个提示，但我不知道该怎么做。
顺便PDOStatement::errorCode返回 00000（表示一切正常）
