的問題 ，如果我去了現場我想編輯，然後單擊更新我的href我採取了一個頁面來輸入新的值，我這樣做，updateameac.php顯示成功，但我看這些字段並沒有被編輯。
我想
我想編輯在數據庫中反映本質上它的工作笑。當談到PHP時，我是一個begginer，所以我希望你們中的一個很好的程序員能夠解決我的問題。
我懷疑我沒有在updateameac.php中正確地描述字段值，我不知道如何糾正它。
在您的更新PHP頁面..我看不出你從你的形式傳遞值。此外，你的代碼容易受到注入攻擊..我真的希望這不是現場。 – Daedalus 2013-04-07 03:54:53
@ updateameac.php，啓動的變量在哪裏？ – daison12006013 2013-04-07 04:09:26
