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.
数据库的数据更新
if(isset($id))
{
if(!MySQL
(和PHP搭配之最佳组合)_connect("localhost","用户名","密码"))
{echo"无法联接数据库";
exit();
}
if(isset($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" ;
$result=MySQL
(和PHP搭配之最佳组合)_db_query("elong",$query); //执行写入
if (!$result)
{echo "发生错误!";
exit();
}
echo "$id 已经更新!
