这篇文章主要介绍了php实现分页功能的3种方法,感兴趣的小伙伴们可以参考一下
;
$page=($pageval-1)*$pagesize;
$page.=',';
}
if($num > $pagesize){
if($pageval<=1)$pageval=1;
echo "共 $num 条".
" <a href=$url?page=".($pageval-1).">上一页</a> <a href=$url?page=".($pageval+1).">下一页</a>";
}
$SQL="SELECT * FROM `message` limit $page $pagesize ";
$query=mysql_query($SQL);
while($row=mysql_fetch_array($query)){
?>
<table width=500 border="0" cellpadding="5" cellspacing="1" bgcolor="#add3ef">
<tr bgcolor="#eff3ff">
<td>标题:<?php echo $row[title]?></td> <td>时间:<?php echo $row[lastdate]?></td>
</tr>
<tr bgcolor="#eff3ff">
<td> 用户:<?php echo $row[user]?></td><td></td>
</tr>
<tr>
<td>内容:<?php echo htmtocode($row[content]);?></td>
</tr>
<br>
</table>
<?php
}
?>
方法3:
<script> function viewpage(p){ if(window.XMLHttpRequest){ var xmlReq = new XMLHttpRequest(); } else if(window.ActiveXObject) { var xmlReq = new ActiveXObject('Microsoft.XMLHTTP'); } var formData = "page="+p; xmlReq.onreadystatechange = function(){ if(xmlReq.readyState == 4){ document.getElementByIdx_x('content2').innerHTML = xmlReq.responseText; } } xmlReq.open("post", "hotel_list.php", true); xmlReq.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlReq.send(formData); return false; } </script>
脚本2:
header("Content-Type:text/html;charset=GB2312"); $pagesize=10; //echo $_POST['page']; $result = mysql_query("Select count(DISTINCT hotelname) FROM ".TBL_HOTELS); $myrow = mysql_fetch_array($result); $numrows=$myrow[0]; $pages=intval($numrows/$pagesize); if ($numrows%$pagesize) $pages++; if (isset($_POST['page'])){ $page=intval($_POST['page']); } else{ //设置为第一页 $page=1; } $first=1; $prev=$page-1; $next=$page+1; $last=$pages; //计算记录偏移量 $offset=$pagesize*($page - 1); //读取指定记录数 $result=mysql_query("select `hotelname` , count( * ) from ".TBL_HOTELS." GROUP BY `hotelname` order by id desc limit $offset,$pagesize"); $num = mysql_num_rows($result); while ($row = mysql_fetch_array($result,MYSQL_NUM)) { $hotelname[] = $row[0]; $countpeople[] = $row[1]; } for($a=0;$a<$num;$a++) { //$result=mysql_query("select count(title) from " . TBL_Comments ." where `title`=\"".$title[$a]."\""); //$row = mysql_fetch_row($result); echo "<TABLE style=\"MARGIN-BOTTOM: 20px\" cellSpacing=0 cellPadding=0 width=100% border=0>\n"; echo "<TBODY>\n"; echo "<TR>\n"; echo "<TD style=\"PADDING-TOP: 5px\" vAlign=top align=left width=80>\n"; //rating_bar($title[$a],5); echo "</TD>\n"; echo "<TD style=\"PADDING-TOP: 5px\" align=left width=100%><A title=$hotelname[$a] style=\"FONT-SIZE: 14px\" href=#>$hotelname[$a]</A>\n"; echo "</TD></TR>\n"; echo " <TR>\n"; echo "<TD></TD>\n"; echo "<TD style=\"PADDING-LEFT: 0px\">\n"; echo "<IMG src=\"images/comment.gif\" border=0> 推荐人数:($countpeople[$a]) |\n"; echo "<SPAN>平均分:<STRONG></STRONG> (".$count."票) | 评论数:()</SPAN>\n"; echo "</TD></TR></TBODY></TABLE>\n"; } echo "<TABLE style=\"MARGIN-TOP: 30px\" cellSpacing=0 cellPadding=0 width=\"100%\""; echo "border=0>"; echo "<TBODY><TR><TD colSpan=3 height=20>"; echo "<DIV align=center>"; echo "<P align=left><FONT color=red>第".$page."页/总".$pages."页 | 总".$numrows."条</FONT> | "; if ($page>1) echo "<a onclick=\"viewpage(".$first.")\" href='#'>首页</a> | "; if ($page>1) echo "<a onclick=\"viewpage(".$prev.")\" href='#'>上页</a> | "; if ($page<$pages) echo "<a onclick=\"viewpage(".$next.")\" href='#'>下页</a> | "; if ($page<$pages) echo "<a onclick=\"viewpage(".$last.")\" href='#'>尾页</a>"; echo "转到第 <INPUT maxLength=3 size=3 value=1 name=goto_page> 页 <INPUT hideFocus onclick=\"viewpage(document.all.goto_page.value)\" type=button value=Go name=cmd_goto>"; echo "</P></DIV></TD></TR></TBODY></TABLE>";
