案頭中心(三) 修改資料庫

下面這個程式在你輸入id後就把那個id的資料列出來。然後你就可以修改後寫入了.

資料庫的資料更新

if(isset($id))
{
if(!MySQL_connect("localhost","使用者名稱","密碼"))
{echo"無法聯結資料庫";
exit();
}
if(isset($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'" ;
$result=mysql_db_query("elong",$query); //執行寫入

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

";
echo "

echo "回到首頁";
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 "發生錯誤!";
exit();
}
$r=mysql_fetch_array($result);
$id = $r["id"];
$url = $r["url"];
$mess = $r["mess"];
$fromx = $r["fromx"];
$url1 = $r["url1"];
$mess1 = $r["mess1"];
$fromx1 = $r["fromx1"];
$url2 = $r["url2"];
$mess2 = $r["mess2"];
$fromx2 = $r["fromx2"];
$url3 = $r["url3"];
$mess3 = $r["mess3"];
$fromx3 = $r["fromx3"];
echo"

}
else
{?>

請輸放需要更改的id:
