謝謝各位大大的回覆：
我現在碰到了一個問題
我上下一頁都寫好了
但按下一頁，網址的變數是有在跑啦！！但內容卻沒變，不知是哪裡寫錯
請大大幫我指證一下，謝~~
以下是我的程式
------------------------------------------------------
<?
//計算筆數
$str="select count(*) from album";
$list=mysql_query($str,$link);
$start_num=$read_num*($page_num-1);
list($album_count)=mysql_fetch_row($list);
//下一頁
$pages=intval($album_count/$read_num)+1;
if($page_num>$pages){$page_num=$pages;}
?>
<div align="center">目前共有<font face="Arial" color="red"><? echo $album_count; ?></font>本相簿</div>
<td height="40" width="120" valign="top" align="center">

<?

if($page_num<1){$page_num=1;}
$start_num=$read_num * ($page_num-1);
$str="select album_no, album_date, MyFile, album_name, album_describ from album order by $sort limit

$album_name=substr($album_name,0,12).".....";
}
if($close_html){ //關閉HTML語法功能之後，進行資料轉換。

$j++;
if ($j % 5 == 0) {echo "</tr>\n";}
}

?>
<p></p>
