yii分页组件用法实例分析
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:
publicfunctionactionIndex(){ $user=User::model(); //分页的使用 $count=$user->count();//获取总页数 $pagesize=3;//每一页显示的记录条数 $page=newPage($count,$pagesize); $sql="select*from{{user}}$page->limit"; $info=$user->findAllBySql($sql); $show_page=$page->fpage(); $this->renderPartial("index",array("info"=>$info,'show_page'=>$show_page)); }
在view页面,遍历info即可获取信息,输出show_page即可显示分页列表等信息。
现附上page.php代码如下:
<?php /** *分页类,以组件形式存在于componnets文件中 */ classPage{ private$total;//数据表中总记录数 private$listRows;//每页显示行数 private$limit; private$uri; private$pageNum;//页数 private$config=array('header'=>"个记录","prev"=>"上一页","next"=>"下一页","first"=>"首页","last"=>"尾页"); private$listNum=8; /* *$total *$listRows */ publicfunction__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(); } privatefunctionsetLimit(){ return"Limit".($this->page-1)*$this->listRows.",{$this->listRows}"; } privatefunctiongetUri($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$this->limit; else returnnull; } privatefunctionstart(){ if($this->total==0) return0; else return($this->page-1)*$this->listRows+1; } privatefunctionend(){ returnmin($this->page*$this->listRows,$this->total); } privatefunctionfirst(){ $html=''; if($this->page==1) $html.=''; else $html.="<ahref='{$this->uri}&page=1'>{$this->config["first"]}</a>"; return$html; } privatefunctionprev(){ $html=''; if($this->page==1) $html.=''; else $html.="<ahref='{$this->uri}&page=".($this->page-1)."'>{$this->config["prev"]}</a>"; return$html; } privatefunctionpageList(){ $linkPage=""; $inum=floor($this->listNum/2); for($i=$inum;$i>=1;$i--){ $page=$this->page-$i; if($page<1) continue; $linkPage.="<ahref='{$this->uri}&page={$page}'>{$page}</a>"; } $linkPage.="{$this->page}"; for($i=1;$i<=$inum;$i++){ $page=$this->page+$i; if($page<=$this->pageNum) $linkPage.="<ahref='{$this->uri}&page={$page}'>{$page}</a>"; else break; } return$linkPage; } privatefunctionnext(){ $html=''; if($this->page==$this->pageNum) $html.=''; else $html.="<ahref='{$this->uri}&page=".($this->page+1)."'>{$this->config["next"]}</a>"; return$html; } privatefunctionlast(){ $html=''; if($this->page==$this->pageNum) $html.=''; else $html.="<ahref='{$this->uri}&page=".($this->pageNum)."'>{$this->config["last"]}</a>"; return$html; } privatefunctiongoPage(){ return'<inputtype="text"onkeydown="javascript:if(event.keyCode==13){varpage=(this.value>'.$this->pageNum.')?'.$this->pageNum.':this.value;location=\''.$this->uri.'&page=\'+page+\'\'}"value="'.$this->page.'"style="width:25px"><inputtype="button"value="GO"onclick="javascript:varpage=(this.previousSibling.value>'.$this->pageNum.')?'.$this->pageNum.':this.previousSibling.value;location=\''.$this->uri.'&page=\'+page+\'\'">'; } functionfpage($display=array(0,1,2,3,4,5,6,7,8)){ $html[0]="共有<b>{$this->total}</b>{$this->config["header"]}"; $html[1]="每页显示<b>".($this->end()-$this->start()+1)."</b>条,本页<b>{$this->start()}-{$this->end()}</b>条"; $html[2]="<b>{$this->page}/{$this->pageNum}</b>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(); $fpage=''; foreach($displayas$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。
