你这个太麻烦我给你推荐一个

<?php

var $pre_page='<';//上一页

var $next_bar='>>';//下一分页条

调用方法：

<?
include("classpage.php");
$queryrow = $DB->query("SELECT * FROM article where article_sortid='$cls' and type='1' ORDER BY article_id DESC");
$rows=$DB->num_rows($queryrow);
$total=$rows;
$pagesize=15;
$currentRow = empty($_GET['page']) ? 0 : ($_GET['page']-1)* $pagesize;
$queryId = $DB->query("SELECT * FROM article where article_sortid='$cls' and type='1' ORDER BY article_id DESC limit $currentRow,$pagesize");
$iiii=1;
while ($a_array=$DB->fetch_array($queryId)) {
?>
<table width="674" border="0" cellspacing="0" cellpadding="0" height="30px">
<tr>
<td width="54"> </td>
<td width="87" align="center" class="news" style="font-size:12px;">
<?php
if($iiii>10)
{
echo $iiii;
}
else
{
echo '0'.$iiii;
}
?>
</td>
<td width="371" class="news" style="font-size:12px;"><a href="newslist.php?id=<?=$a_array[article_id]?>"><?=$a_array['article_title']?></a></td>
<td width="73" class="news" style="font-size:12px;"><?=$a_array['article_hits']?></td>
<td width="89" class="news" style="font-size:12px;"><?=substr($a_array['article_addtime'],0,10)?></td>

</tr>
</table>
<?php
$iiii++;
}
if ($iiii==1) echo "抱歉，没有搜索到任何信息。";
?>
<table width="720" border="0" cellspacing="0" cellpadding="0">
<tr>
<td class="dibu" align="center" valign="top">
<table width="98%" border="0" align="center" cellpadding="0" cellspacing="0">

<tr>
<td width="52%" height="10" align="center"></td>
<td width="48%" align="center"></td>
</tr>
<tr>
<td height="28" colspan="2" align="center" valign="bottom" style="font-size:12px">
<?php
$page=new page(array('total'=>$total,'perpage'=>$pagesize));
$pagehtml=$page->show(6,"page","curr");
echo $pagehtml;
?>

这个是调用方法
$pagehtml=$page->show(6,"page","curr"); 看到这个没有里面是6 我调用的是6这种方法显示的里面可以选择0 ，1， 2， 3， 4， 5， 6，六中方法分页显示不同具体的你可以试试我目前用6的比较多点呵呵

代码是不会给你敲了给你个思路直接给你代码对你没好处
你在文本域中设置一个时间onpressup事件定义代码为空格的代码用JS接收
接收后先去空格然后跳转页面参数才用GET方式提交不懂可以继续问我
