php留言板分页问题

请问问什么不能跳到下一页<?include 'conn.php'; include("head.php"); ?> <?echo "<div align='center'><a href='add.php'>继续添加</a></div>"; ?> <table width=500 border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#add3ef"> <?php $db=mysql_connect("localhost","root",""); mysql_select_db("form",$db); $pagesize=5; $res=mysql_query("select count(*) from message " ,$db); $myrow = mysql_fetch_array($res); $numrows=$myrow[0]; $pages=intval($numrows/$pagesize); if ($numrows%$pagesize) $pages++; if (!isset($page)) $page=1; if (isset($ys)) if ($ys>$pages) $page=$pages; else $page=$ys; $offset=$pagesize*($page-1); $res=mysql_query("select id,title from message order by id desc limit $offset,$pagesize" ,$db); if ($myrow = mysql_fetch_array($res)) { $i=0; ?> <table width="101%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="5%" bgcolor="#E1E9FB"></td> <td width="95%" bgcolor="#E1E9FB"><font color="#FF6666" size="2">内容</font></td> </tr> <?php do { $i++; ?> <tr> <td width="5%" bgcolor="#E6F2FF"><?php echo $i;?></td> <td width="95%" bgcolor="#E6F2FF"><font size="2"> <a href="javascript:popwin('view.php?id=<?php echo $myrow[0];?>')" ><?php echo $myrow[1];?></a></font></td> </tr> <?php } while ($myrow = mysql_fetch_array($res)); echo "</table>" ; } echo "<div align='center'>共有".$pages."页(".$page."/".$pages.")<br>"; for ($i=1;$i<$page;$i++) echo "<a href='list.php?page=".$i."'>第".$i ."页</a> "; echo "第".$page."页 "; for ($i=$page+1;$i<=$pages;$i++) echo "<a href='list.php?page=".$i."'>第".$i ."页</a> "; echo "<br>"; echo "<form action='list.php' method='post'> "; $first=1; $prev=$page-1; $next=$page+1; $last=$pages; if ($page>1) { echo "<a href='list.php?page=".$first."'>首页</a> "; echo "<a href='list.php?page=".$prev."'>上一页</a> "; } if ($page<$pages) { echo "<a href='list.php?page=".$next."'>下一页</a> "; echo "<a href='list.php?page=".$last."'>尾页</a> "; } echo "转到<input type=text name='ys' size='2' value=".$page.">页"; echo "<input type=submit name='Submit' value='Go'>"; echo "</form>"; echo "</div>"; ?>

按下一页仍在 第一页

Answer 1

没看到你页面有接受 $page的地方?

Answer 2

你的页数 $ys变量拿来干什么。当前页你都没传过来。
