PHP搜索结果分页显示问题-tutorial php-php.cn

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>";}

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">		<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>

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';

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://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 '<a href="?keyword='.$keyword.'curPage=1">首页</a>丨';            echo '<a href="?keyword='.$keyword.'&curPage='.($this->curPage - 1).'">上一页</a>丨';			echo '<a href="?curPage='.$keyword.'&curPage='.($this->curPage + 1).'">下一页</a>丨';            echo '<a href="?curPage='.$keyword.'&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 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 '<a href="?keyword='.$keyword.'curPage=1">首页</a>丨';            echo '<a href="?keyword='.$keyword.'&curPage='.($this->curPage - 1).'">上一页</a>丨';            echo '<a href="?curPage='.$keyword.'&curPage='.($this->curPage + 1).'">下一页</a>丨';            echo '<a href="?curPage='.$keyword.'&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";        }

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($result)){                echo "<img  src=".$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 = $curPage;        }        private function showFoot(){            echo '<a href="?keyword='.$this->keyword.'&curPage=1">首页</a>丨';            echo '<a href="?keyword='.$this->keyword.'&curPage='.($this->curPage - 1).'">上一页</a>丨';            echo '<a href="?keyword='.$this->keyword.'&curPage='.($this->curPage + 1).'">下一页</a>丨';            echo '<a href="?keyword='.$this->keyword.'&curPage='.$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>";}?>

调用时需要加参数。
$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

<?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($result)){                echo "<img  src=".$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 = $curPage;        }        private function showFoot(){            echo '<a href="?search='.$this->keyword.'&curPage=1">首页</a>丨';            echo '<a href="?search='.$this->keyword.'&curPage='.($this->curPage - 1).'">上一页</a>丨';            echo '<a href="?search='.$this->keyword.'&curPage='.($this->curPage + 1).'">下一页</a>丨';            echo '<a href="?search='.$this->keyword.'&curPage='.$this->totalPages.'">尾页</a>丨';            echo "共有".$this->totalPages."页丨";            echo "当前第 <font color=red>".$this->curPage."</font> 页";        }  }$keyword=$_REQUEST['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>";}?>
