當我更改產品數量並更新數據時，它會丟失，而update命令實際上會將總列設置爲0（實際上更新代碼工作正常，直到我編輯了表單頁面包括在底部總，下面是屏幕截圖，以及更新代碼更新數據庫

你的量被設置爲0，因爲INTVAL不能投你的量的有效數字。您需要調試$ item提交中返回的內容。

當我有後期結果，它給這個數組（[item] => Array（[0] => Array（[Pquantity] => 2）[1] => Array（[Pidno] = > 123））[tprice] => 24 [submit2] =>提交），因爲這個字段我輸入的數量是2 – lostty84 2012-02-15 13:35:46

您的輸出顯示$ item沒有'Pquantity'鍵。該值在一個子陣列中。看起來你需要$ item [0] ['Pquantity']或在你的循環$ item [$ i] ['Pquantity'] – davidethell 2012-02-15 21:47:20

那是真的，我可以看到你在說什麼 – lostty84 2012-02-16 09:28:03

腳本你在哪裏得到上線

"<input type='text' name='item[$i][Pquantity]' id='Pquantity' value='".htmlspecialchars($row['Pquantity'])."' />"

的$i？您是否拋出所有錯誤，以便您可以看到PHP是否在抱怨什麼？你的錯誤級別是多少？

另外，你的代碼的最後一塊可以使用SUM SQL聚合函數，如：

SELECT SUM(Tprice) FROM repplac WHERE Uname = '{$_SESSION['username']}'
