桌面中心(三)修改数据库
作者：elong
下面这个程序在你输入id后就把那个id的数据列出来。然后你就可以修改后写入了.
<html>
<body>
<h1>数据库的数据更新</h1>
<?
if(isset($id))
{
if(!mysql_connect("localhost","用户名","密码"))
{echo"无法联接数据库";
exit();
}
if(isset($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" ;
$result=mysql_db_query("elong",$query); //执行写入
if (!$result)
{echo "发生错误!";
exit();
}
echo "$id 已经更新!
";
echo "<table>n
<tr>n
<td>ID<td>$id</tr>n
<tr>n

echo "<a href=set.htm>回到首页</a>";
exit();
}
$query="SELECT id,url,mess,fromx,url1,mess1,fromx1,url2,mess2,fromx2,url3,mess3,fromx3 from $jpg
where id=$id" ;
$result=mysql_db_query("elong",$query);
if (!$result)
{echo "发生错误!";
exit();
}
$r=mysql_fetch_array($result);
$id = $r["id"];
$url = $r["url"];
$mess = $r["mess"];
