已更新我的帖子6/15/14我的新問題是我有每個文本輸入旁邊的複選框，這將指示（如果選中）文本框中的文本是正確的答案。但是，當我對某個特定答案的複選框進行更改時，它未被正確保存。從數組中提取變量並插入到mysql
這裏是我的全部更新的代碼

詢問'mysqli_error（）'查詢是否成功。 – mario
mysqli_error（）不會顯示任何錯誤，並且每個文本框的第一個字符都被插入到數據庫中，因此我不希望返回錯誤。我認爲我的錯誤與php本身有關，儘管我無法發現它。 – Jayreis
你的問題不包含任何有關實際表單或'$ _POST'結構的信息。另外'error_reporting'。 – mario
