PHP搜索结果分页显示问题
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($result)){ echo "
"; echo "
"; } } private function setCurPage($curPage){ if($curPage $this->totalPages){ $curPage = $this->totalPages; } $this->curPage = $curPage; } private function showFoot(){ echo '首页丨'; echo '上一页丨'; echo '下一页丨'; echo '尾页丨'; echo "共有".$this->totalPages."页丨"; echo "当前第 ".$this->curPage." 页"; } }$keyword=$_POST['search'];$sql=mysql_query("select * from didian where name like '%$keyword%'");$raw=@mysql_fetch_object($sql);if(!$raw){ echo "您搜索的信息不存在，请使用类似的关键字进行检索!";}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($keyword){ case '桂林':$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':$pages = new Page('SELECT * FROM `image_xishuangbanna`', 3);break;} 后面是html搜索框跳转
不知道为什么这样。。求教。。。
回复讨论(解决方案)
翻页你没有把keyword参数带过去。
private function showFoot(){
echo '首页丨';
echo '上一页丨';
echo '下一页丨';
echo '尾页丨';
echo "共有".$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';

首页没参数怎么办？这是首页的http://localhost:808/Web/search.php
这是第二页的http://localhost:808/Web/search.php?curPage=&curPage=2
表单的action不用加什么吗？我按你的改了
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"; } $keyword 并没有传入 showFoot，当然是不行的
$keyword 并没有传入 showFoot，当然是不行的
那又该如何改才好呢？不知道哪改好。。
至少需要这样
echo ' rivate function showFoot(){ echo '首页丨'; echo '上一页丨'; echo '下一页丨'; echo '尾页丨'; echo "共有".$this->totalPages."页丨"; echo "当前第 ".$this->curPage." 页"; }
你这个方法不能获取到$keyword，所以为空。
改成这样，加个参数 dispNum = $dispNum; $this->keyword = $keyword; $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($result)){ echo " "; echo "
"; } } private function setCurPage($curPage){ if($curPage $this->totalPages){ $curPage = $this->totalPages; } $this->curPage = $curPage; } private function showFoot(){ echo '首页丨'; echo '上一页丨'; echo '下一页丨'; echo '尾页丨'; echo "共有".$this->totalPages."页丨"; echo "当前第 ".$this->curPage." 页"; } }$keyword=$_POST['search'];$sql=mysql_query("select * from didian where name like '%$keyword%'");$raw=@mysql_fetch_object($sql);if(!$raw){ echo "您搜索的信息不存在，请使用类似的关键字进行检索!";}?>
调用时需要加参数。
$pages = new Page('SELECT * FROM `image_guilin`', $keyword, 3);

$pages = new Page('SELECT * FROM `image_guilin`', $keyword, 3);
还是不行耶。。我搜索出来的首页没带后缀参数http://localhost:808/Web/search.php一直这个状态
至少需要这样
echo ' $keyword=$_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 dispNum = $dispNum; $this->keyword = $keyword; $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($result)){ echo " "; echo "
"; } } private function setCurPage($curPage){ if($curPage $this->totalPages){ $curPage = $this->totalPages; } $this->curPage = $curPage; } private function showFoot(){ echo '首页丨'; echo '上一页丨'; echo '下一页丨'; echo '尾页丨'; echo "共有".$this->totalPages."页丨"; echo "当前第 ".$this->curPage." 页"; } }$keyword=$_REQUEST['search'];$sql=mysql_query("select * from didian where name like '%$keyword%'");$raw=@mysql_fetch_object($sql);if(!$raw){ echo "您搜索的信息不存在，请使用类似的关键字进行检索!";}?>
$keyword=$_POST['search'];
