的代碼應該是一個客戶書爲了保存到數據庫中，它完美罰款一本書。第76到81行有插入語句。然而，如果該人已經購買了兩本書，那麼只有最後一本書被添加到數據庫中。添加屏幕截圖：

這就是它在我的網站上的樣子。正如你所看到的人已經選擇購買兩本書： http://postimg.org/image/3kj1gvytx/ 然而，這是我在我的phpmyadmin網站獲得： http://postimg.org/image/k85hs56xj/ 我們可以看到，只有第二本書（生物學）被存儲在數據庫中。以及這兩本書的總數

任何想法如何我可以解決這個問題，並存儲這兩本書。

感謝

在這種情況下，你可以使用Ajax的異步請求添加項目，而不刷新頁面插入語句。 – DDeme 2015-03-19 12:38:48

我該怎麼做？我從來沒有真正使用過Ajax – resontant81 2015-03-19 12:39:51

等一下（我會在這裏更新）... – DDeme 2015-03-19 12:52:44

當你不知道的Ajax，你可以做這樣的事情： 1）重置$結果數組，再次對MySQL查詢選擇項目。 2）用while循環將每個選定的值插入到DB中。

reset($result); 
while($row=mysqli_fetch_array($result)) 
{ 
    $ins = mysqli_query($con, "Here goes insert statement for each"); 
}

編輯

$ISBN = $cart_itm["ISBN"]; 
$con = mysqli_connect("localhost","root","","yourbasename"); 
$result = mysqli_query($con, "SELECT Title,BookDesc, Price FROM books  
WHERE ISBN='$ISBN'"); 
while($row=mysqli_fetch_array($result) 
{ 
    $insert = mysqli_query($con, "INSERT....."); 
}

我假設id把代碼放在if（isset（$ _ POST ['submit_btn']））{ line？ – resontant81 2015-03-19 12:58:58

是的，這是你應該把這個代碼放在哪裏。 – DDeme 2015-03-19 13:00:02

獲得一個錯誤，說出現意外{在第79. – resontant81 2015-03-19 13:01:58
