桌面中心(三)修改數據庫
作者:elong

下面這個程序在你輸入id後就把那個id的數據列出來。然後你就可以修改後寫入瞭.
<html>
<body>
<h1>數據庫的數據更新</h1>
<?
if(isset($id))
{
if(!MySQL(和PHP搭配之最佳組合)_connect(“localhost”,”用戶名”,”密碼”))
{echo”無法聯接數據庫”;
exit();
}
if(isset($url))
{
$query=”update $jpg set id=’$id’,url=’$url’,mess=’$mess’,
fromx=’$fromx’,url1=’$url1’,mess1=’$mess1’,fromx1=’$fromx1’,url2=’$url2’,
mess2=’$mess2’,fromx2=’$fromx2’,url3=’$url3’,mess3=’$mess3’,fromx3=’$fromx3’
where id=’$id’” ;
$result=MySQL(和PHP搭配之最佳組合)_db_query(“elong”,$query); //執行寫入

if (!$result)
{echo “發生錯誤!”;
exit();
}
echo “$id 已經更新!

“;
echo “<table>n

exit();

$query=”SELECT id,url,mess,fromx,url1,mess1,fromx1,url2,mess2,fromx2,url3,mess3,fromx3 from $jpg
