原来发表过一个脱离数据库的分页类,最近使用的时候发现有些时候搜索的东西过于大的时候,采用url传递参数的方式,可能会有一定的影响或者叫已知的bug,这次做了一些扩展,同时兼容了以前的模式,使用上面很简单的,只需要多设置一个参数就可以了代码如下:
/**
* 功能: 分页类,根据提供的数据总量和页面大小

*/
class pagination
{
var $result = array();
var $pVar = "myp";//page参数分页记数
var $urlParamStr = ""; //页面的所有参数
var $sqlMoveNumber = 0; //数据的偏移量
var $is_post = false;
public function pagination()
{
}
public function set($sum,$pageSize,$page="",$is_post = false)
{
$this->is_post = $is_post;
$this->pVar = defined('PAGE_BAR') ? PAGE_BAR : 'myp' ;
$url = $_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING'];
//计算出总页数
$curPage = $this->getCurPage();
$temp['sumPage'] = ceil($sum/$pageSize);
//修改了,页码超出的bug
if($curPage>$temp['sumPage']) $curPage=$temp['sumPage'];
$temp['curPage'] = $curPage;
$temp['nextPage'] = $temp['sumPage'] > $curPage ? ($curPage+1) : $temp['sumPage'];
$temp['upPage'] = $curPage >1 ? $curPage-1 :1;
$temp['endPage'] = $temp['sumPage'];
$this->urlParamStr = $this->_makeUrl($url);
$temp['urlPageStr'] = ($page=="") ? $this->_makeUrl($url) : $page.$this->urlParamStr;
$this->sqlMoveNumber = $curPage $temp['sqlMoveNumber'] = $this->sqlMoveNumber;
$temp['rowNo'] = $sum;
$this->result = $temp;
return $this->result;
//print_r($temp);exit();
}
public function getSqlMove()
{
return $this->sqlMoveNumber;
}
public function getFooter()
{
$str= "共有 {$this->result['rowNo']} 条 result['upPage']}'";
if($this->is_post) $str .=" onclick='return sanshi_page_post(this.href,{$this->result['upPage']});' ";
$str .=" >上一页 ";
$str .=" 当前 {$this->result['curPage']} 页";
$str .=" 共有 {$this->result['sumPage']} 页";
$str .=" result['nextPage']}'";
if($this->is_post) $str .=" onclick='return sanshi_page_post(this.href,{$this->result['nextPage']});' ";
$str .=" >下一页";
return $str;
}
public function getJumpPage()
{
if($this->is_post)
{
$str = " 跳到第
