yii分页组件用法实例分析

前端之家收集整理的这篇文章主要介绍了yii分页组件用法实例分析前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

本文实例讲述了yii分页组件用法分享给大家供大家参考,具体如下:

该案例使用时,分页类在yii框架中以组件的形式存在于components中。

action代码如下:

count(); //获取总页数 $pagesize=3; //每一页显示的记录条数 $page=new Page($count,$pagesize); $sql="select * from {{user}} $page->limit"; $info=$user->findAllBysql($sql); $show_page=$page->fpage(); $this->renderPartial("index",array("info"=>$info,'show_page'=>$show_page)); }

在view页面,遍历info即可获取信息,输出show_page即可显示分页列表等信息。

现附上page.PHP代码如下:

PHP;"> "个记录","prev"=>"上一页","next"=>"下一页","first"=>"首 页","last"=>"尾 页"); private $listNum=8; /* * $total * $listRows */ public function __construct($total,$listRows=10,$pa=""){ $this->total=$total; $this->listRows=$listRows; $this->uri=$this->getUri($pa); $this->page=!empty($_GET["page"]) ? $_GET["page"] : 1; $this->pageNum=ceil($this->total/$this->listRows); $this->limit=$this->setLimit(); } private function setLimit(){ return "Limit ".($this->page-1)*$this->listRows.",{$this->listRows}"; } private function getUri($pa){ $url=$_SERVER["REQUEST_URI"].(strpos($_SERVER["REQUEST_URI"],'?')?'':"?").$pa; $parse=parse_url($url); if(isset($parse["query"])){ parse_str($parse['query'],$params); unset($params["page"]); $url=$parse['path'].'?'.http_build_query($params); } return $url; } function __get($args){ if($args=="limit") return $this->limit; else return null; } private function start(){ if($this->total==0) return 0; else return ($this->page-1)*$this->listRows+1; } private function end(){ return min($this->page*$this->listRows,$this->total); } private function first(){ $html=''; if($this->page==1) $html.=''; else $html.=" {$this->config["first"]} "; return $html; } private function prev(){ $html=''; if($this->page==1) $html.=''; else $html.=" {$this->config["prev"]} "; return $html; } private function pageList(){ $linkPage=""; $inum=floor($this->listNum/2); for($i=$inum; $i>=1; $i--){ $page=$this->page-$i; if($page<1) continue; $linkPage.=" {$page} "; } $linkPage.=" {$this->page} "; for($i=1; $i<=$inum; $i++){ $page=$this->page+$i; if($page<=$this->pageNum) $linkPage.=" {$page} "; else break; } return $linkPage; } private function next(){ $html=''; if($this->page==$this->pageNum) $html.=''; else $html.=" {$this->config["next"]} "; return $html; } private function last(){ $html=''; if($this->page==$this->pageNum) $html.=''; else $html.=" {$this->config["last"]} "; return $html; } private function goPage(){ return ' IoUsSibling.value;location=\''.$this->uri.'&page=\'+page+\'\'"> '; } function fpage($display=array(0,1,2,3,4,5,6,7,8)){ $html[0]=" 共有{$this->total}{$this->config["header"]} "; $html[1]=" 每页显示".($this->end()-$this->start()+1)."条,本页{$this->start()}-{$this->end()}条 "; $html[2]=" {$this->page}/{$this->pageNum}页 "; $html[3]=$this->first(); $html[4]=$this->prev(); $html[5]=$this->pageList(); $html[6]=$this->next(); $html[7]=$this->last(); $html[8]=$this->goPage(); $fpage=''; foreach($display as $index){ $fpage.=$html[$index]; } return $fpage; } }

希望本文所述对大家基于yii框架的PHP程序设计有所帮助。
