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($result)){
echo ;
echo
;
}
}
private function setcurpage($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 .$this->curpage. 页;
}
}
$keyword=$_post['search'];
$sql=mysql_query(select * from didian where name like '%$keyword%');
[email protected]_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。。。
------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
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 = $curpage;
}
private function showfoot(){
echo 'keyword.'&curpage=1>首页丨';
echo 'keyword.'&curpage='.($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.$this->totalpages.页丨;
echo 当前第 .$this->curpage. 页;
}
}
$keyword=$_request['search'];
$sql=mysql_query(select * from didian where name like '%$keyword%');
[email protected]_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!;
}
