PHP搜索结果分页显示问题。。
首页显示没问题，翻页显示数据没有。。。代码
include_once("script/conn.php");<br /> class Page{<br /> private $curPage;//当前页面<br /> private $totalPages;//数据总共分多少页显示<br /> private $dispNum;//每页显示的数据条数<br /> private $queryStr;//查询的SQL语句<br /> private $limitStr;//查询语句后面的limit控制语句<br /> private $currentPage;//获取当前页面<br /> public function __construct($queryStr='',$dispNum=3){ <br /> $result = mysql_query($queryStr);<br /> $totalNum = mysql_num_rows($result);<br /> $this->dispNum = $dispNum;<br /> $currentPage = basename ( $_SERVER["PHP_SELF"] ); //返回路径中的文件名部分<br /> $this->totalPages = ceil($totalNum / $dispNum);<br /> $this->queryStr = $queryStr;<br /> $temp = (isset($_GET["curPage"]) ? $_GET["curPage"] : 1);<br /> $this->setCurPage($temp);<br /> $this->showCurPage();<br /> $this->showFoot();<br /> } <br /> private function showCurPage(){<br /> $this->limitStr = ' LIMIT '.(($this->curPage - 1)* $this->dispNum).','.$this->dispNum;<br /> $result = mysql_query($this->queryStr.$this->limitStr);<br /> while($row = mysql_fetch_assoc($result)){<br /> echo "<img src=".$row['Image']." / alt="PHP搜索结果分页显示有关问题。" >";<br /> echo "<br/>";<br /> }<br /> }<br /> private function setCurPage($curPage){<br /> if($curPage < 1){<br /> $curPage = 1;<br /> }<br /> else if($curPage > $this->totalPages){<br /> $curPage = $this->totalPages;<br /> }<br /> $this->curPage = $curPage;<br /> }<br /> private function showFoot(){<br /> echo '<a href="?curPage=1">首页</a>丨';<br /> echo '<a href="?curPage='.($this->curPage - 1).'">上一页</a>丨';<br /> echo '<a href="?curPage='.($this->curPage + 1).'">下一页</a>丨';<br /> echo '<a href="?curPage='.$this->totalPages.'">尾页</a>丨';<br /> echo "共有".$this->totalPages."页丨";<br /> echo "当前第 <font color=red>".$this->curPage."</font> 页";<br /> }<br /> }<br />$keyword=$_POST['search'];<br />$sql=mysql_query("select * from didian where name like '%$keyword%'");<br />[email protected]_fetch_object($sql);<br />if(!$raw){<br /> 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>";<br />}Nach dem Login kopieren
如果单独这样输出是没问题的。。但加上这条的话翻页就没数据显示了..这是搜索框判断条件
switch($keyword){<br /> case '桂林':$pages = new Page('SELECT * FROM `image_guilin`', 3);break;<br /> case '海南':$pages = new Page('SELECT * FROM `image_hainan`', 3);break;<br /> case '北京':$pages = new Page('SELECT * FROM `image_beijing`', 3);break;<br /> case '九寨沟':$pages = new Page('SELECT * FROM `image_jiuzhaigou`', 3);break;<br /> case '太行山':$pages = new Page('SELECT * FROM `image_taihengshan`', 3);break;<br /> case '香格里拉':$pages = new Page('SELECT * FROM `image_xianggelila`', 3);break;<br /> case '小兴安岭':$pages = new Page('SELECT * FROM `image_xiaoxinganling`', 3);break;<br /> case '西双版纳':$pages = new Page('SELECT * FROM `image_xishuangbanna`', 3);break;<br />}Nach dem Login kopieren
后面是html搜索框跳转
<div id="search_box"><br /> <form id="search_form" method="post" action="search.php"> <br /> <input type="text" id="search" value="城市、景点" onFocus="this.value=''" style="max-width:90%" name="search"/><br /> <input type="submit" id="s_search" value="搜索" name="Submit" onClick="return check(form)"/><br /> </form> <br /> </div>

不知道为什么这样。。求教。。。
------解决思路----------------------$keyword=$_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
