php编辑字段未更新

使用 sql 以及 php . 在申请表中，我有一个 Edit 允许用户更新字段的按钮 doctorFname,doctorLname, idDepartment, and specialty . 当用户输入新数据并单击 save ，它应该发布到 mysql . 这是我的项目的最后一步，我很难弄清楚为什么它没有更新。我可以 delete 并添加 new 用户。我会把代码贴在下面。任何帮助都将不胜感激，因为我离完成任务只有一步之遥。再次感谢！
更新：我已经 error reporting 这就是我得到的错误。 Cannot modify header information - headers already sent by (output started at /Users/moe/Desktop/CRUD/index.php:1) in /Users/moe/Desktop/CRUD/formprocessor.php on line 87 更新2：看了我的 UPDATE 用户单击 update 巴顿，我忘了加一个 ' 进入 sql 声明。在中运行相同的查询之后 sql workbench 为了让它发挥作用，我试着看看我最终是否做对了。但我得到下面的错误 Incorrect integer value: '' for column 'idDepartment' at row 1 更新3：我尝试使用以下正则表达式来获取 integer 价值 idDepartment 自 mysql 期待着一个 int 但是收到一封信 string 相反。这没有帮助，我仍然面临着这个问题。
$idDepart = preg_replace("/[^0-9,.]/", "", $idDepart); Doctor Table ```
