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($result)){ echo ""; echo "<br />"; } } private function setCurPage($curPage){ if($curPage $this->totalPages){ $curPage = $this->totalPages; } $this->curPage = $curPage; } private function showFoot(){ echo '首页丨'; echo 'curPage - 1).'">上一页丨'; echo 'curPage + 1).'">下一页丨'; echo 'totalPages.'">尾页丨'; echo "共有".$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>";}
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':$pages = new Page('SELECT * FROM `image_xishuangbanna`', 3);break;}
后面是html搜索框跳转
<div id="search_box"> </div>
不知道为什么这样。。求教。。。
回复讨论(解决方案)
翻页你没有把keyword参数带过去。
private function showFoot(){
echo ‘首页丨’;
echo ‘curPage – 1).'”>上一页丨’;
echo ‘curPage + 1).'”>下一页丨’;
echo ‘totalPages.'”>尾页丨’;
echo “共有”.$this->totalPages.”页丨”;
echo “当前第 “.$this->curPage.” 页”;
}
这里要加上keyword参数传递。
echo ‘curPage – 1).'”>上一页丨’;

依然没数据呢
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:/
搞gaodaima代码/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 'curPage - 1).'">上一页丨'; echo 'curPage + 1).'">下一页丨'; echo 'totalPages.'">尾页丨'; echo "共有".$this->totalPages."页丨"; echo "当前第 <font color="red">".$this->curPage."</font> 页"; }
$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 'curPage - 1).'">上一页丨'; echo 'curPage + 1).'">下一页丨'; echo 'totalPages.'">尾页丨'; echo "共有".$this->totalPages."页丨"; echo "当前第 <font color="red">".$this->curPage."</font> 页"; }
你这个方法不能获取到$keyword,所以为空。
改成这样,加个参数
<?phpinclude_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 private $keyword;// 关键字 public function __construct($queryStr='', $keyword='', $dispNum=3){ $result = mysql_query($queryStr); $totalNum = mysql_num_rows($result); $this->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($result)){ echo ""; echo "<br />"; } } private function setCurPage($curPage){ if($curPage $this->totalPages){ $curPage = $this->totalPages; } $this->curPage = $curPage; } private function showFoot(){ echo 'keyword.'&curPage=1">首页丨'; echo 'keyword.'&curPage='.($this->curPage - 1).'">上一页丨'; echo 'keyword.'&curPage='.($this->curPage + 1).'">下一页丨'; echo 'keyword.'&curPage='.$this->totalPages.'">尾页丨'; 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>";}?>
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 ‘
首页没有参数呀。。只有下一页地址才带有参数。。
$keyword=$_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
