我創建一個反饋，讓用戶給他們的反饋和使用PHP和庫MySQLi不使用jQuery和AJAX刷新頁面存儲在數據庫中的這種反饋頁面，但問題是，我沒有得到任何插入的數據，雖然我得到了成功的消息 如果有人能幫助我，我會理解，PHP的mysqli阿賈克斯jQuery的

您正在保存數據並返回一個字符串，例如「謝謝..」。 「我沒有插入數據」是什麼意思？不要回復這樣的事情嗎？ – herrjeh42 2013-03-27 07:53:33
什麼是'回聲$ stmt->誤差值;'後您的'$ query2' – 2013-03-27 07:53:43
和：刪除的var_dump，這就可能打破過程:-D – herrjeh42 2013-03-27 07:54:23
