這是錯誤

You have an error in your SQL syntax; check the manual that corresponds

.....

Jobs 
---- 
JobID 
CategoryID 
JobName 
JobDescription 
JobNumber 

Categories 
--------- 
CategoryID // 11 categories.. 
CategoryDescription 

基於來自droplist用戶的選舉，它會選擇分類數據。應貯存在 和插入所有數據用戶在框中領域

進入，如果$表中存在到「Categories.CategotyID」和「Jobs.JobID」是自動遞增，查詢可以是這樣：

$sql = "INSERT INTO Jobs(`JobID`, `CategoryID`, `JobName`,`Description`,`NoStudent`) 
VALUES (NULL,{$table},'$JN','$DES','$NoS'); 

或

$sql = "INSERT INTO Jobs VALUES (NULL,{$table},'$JN','$DES','$NoS'); 

您的查詢包含屬性DuDate，存在到喬布斯？
