最佳回答：

建議你在提交數據給數據庫前做個斷點，輸出一下你的sql語句，這樣可以驗證一下你的sql語句是否有錯了。
$rs=mysql_query($sql1);
$numRecord=mysql_num_rows($rs);
$totalpage=ceil($numRecord/$pagesize);

$recordSql=$sql1." limit ".(($page-1)*$pagesize).",".$pagesize;
echo $recordSql; //這裡看看你浏覽器點擊第二頁時的sql拼裝是否有問題。
//$result=mysql_query($recordSql);
