首页显示没问题，翻页显示数据没有。。。代码
include_once("script/conn.php"); class Page{ private $curPage;//当前页面 private $totalPages;//数据总共分多少页显示 private $dispNum;//每页显示的数据条数 private $queryStr;//查询的SQL语句 private $limitStr;//查询语句后面的limit控制语句 private $currentPage;//获取当前页面 public function __construct($queryStr='',$dispNum=3){ $result = mysql_query($queryStr); $totalNum = mysql_num_rows($result); $this->dispNum = $dispNum; $currentPage = basename ( $_SERVER["PHP_SELF"] ); //返回路径中的文件名部分 $this->totalPages = ceil($totalNum / $dispNum); $this->queryStr = $queryStr; $temp = (isset($_GET["curPage"]) ? $_GET["curPage"] : 1); $this->setCurPage($temp); $this->showCurPage(); $this->showFoot(); } private function showCurPage(){ $this->limitStr = ' LIMIT '.(($this->curPage - 1)* $this->dispNum).','.$this->dispNum; $result = mysql_query($this->queryStr.$this->limitStr); while($row = mysql_fetch_assoc($result)){ echo "<img src=".$row['Image']." / alt="PHP搜索结果分页显示问题" >"; echo "<br/>"; } } private function setCurPage($curPage){ if($curPage < 1){ $curPage = 1; } else if($curPage > $this->totalPages){ $curPage = $this->totalPages; } $this->curPage = $curPage; } private function showFoot(){ echo '<a href="?curPage=1">首页</a>丨'; echo '<a href="?curPage='.($this->curPage - 1).'">上一页</a>丨'; echo '<a href="?curPage='.($this->curPage + 1).'">下一页</a>丨'; echo '<a href="?curPage='.$this->totalPages.'">尾页</a>丨'; echo "共有".$this->totalPages."页丨"; echo "当前第 <font color=red>".$this->curPage."</font> 页"; } }$keyword=$_POST['search'];$sql=mysql_query("select * from didian where name like '%$keyword%'");$raw=@mysql_fetch_object($sql);if(!$raw){ echo "<font color='red'>您搜索的信息不存在，请使用类似的关键字进行检索!</font>";}switch($keyword){ case '桂林':$pages = new Page('SELECT * FROM `image_guilin`', 3);break; case '海南':$pages = new Page('SELECT * FROM `image_hainan`', 3);break; case '北京':$pages = new Page('SELECT * FROM `image_beijing`', 3);break; case '九寨沟':$pages = new Page('SELECT * FROM `image_jiuzhaigou`', 3);break; case '太行山':$pages = new Page('SELECT * FROM `image_taihengshan`', 3);break; case '香格里拉':$pages = new Page('SELECT * FROM `image_xianggelila`', 3);break; case '小兴安岭':$pages = new Page('SELECT * FROM `image_xiaoxinganling`', 3);break; case '西双版纳':$pages = new Page('SELECT * FROM `image_xishuangbanna`', 3);break;}<div id="search_box"> <form id="search_form" method="post" action="search.php"> <input type="text" id="search" value="城市、景点" onFocus="this.value=''" style="max-width:90%" name="search"/> <input type="submit" id="s_search" value="搜索" name="Submit" onClick="return check(form)"/> </form> </div>
翻页你没有把keyword参数带过去。
private function showFoot(){
echo '首页丨';
echo '上一页丨';
echo '下一页丨';
echo '尾页丨';
echo "共有".$this->totalPages."页丨";
echo "当前第 ".$this->curPage." 页";
}
这里要加上keyword参数传递。
echo '上一页丨';

$keyword 并没有传入 showFoot，当然是不行的
调用时需要加参数。
$pages = new Page('SELECT * FROM `image_guilin`', $keyword, 3);
调用时需要加参数。
$pages = new Page('SELECT * FROM `image_guilin`', $keyword, 3);
$keyword=$_POST['search'];
1.你获取参数的名称是search，不是keyword.
2.因为分页是用的是get，所以不能获取。
改成这样就可以了
