本文實例講述了yii分頁組件用法。分享給大家供大家參考，具體如下：
該案例使用時，分頁類在yii框架中以組件的形式存在于components中。
action代碼如下：
public function actionIndex(){ $user=User::model(); //分頁的使用 $count=$user->count(); //獲取總頁數 $pagesize=3; //每一頁顯示的記錄條數 $page=new Page($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頁面，遍歷info即可獲取信息，輸出show_page即可顯示分頁列表等信息。
現附上page.php代碼如下：
<?php/** * 分頁類，以組件形式存在于componnets文件中 */class Page { private $total; //數據表中總記錄數 private $listRows; //每頁顯示行數 private $limit; private $uri; private $pageNum; //頁數 private $config=array('header'=>"個記錄", "prev"=>"上一頁", "next"=>"下一頁", "first"=>"首 頁", "last"=>"尾 頁"); 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 $html.=" <a href='{$this->uri}&page=1'>{$this->config["first"]}</a> "; return $html; } private function prev(){ $html=''; if($this->page==1) $html.=''; else $html.=" <a href='{$this->uri}&page=".($this->page-1)."'>{$this->config["prev"]}</a> "; 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; $linkPage.=" <a href='{$this->uri}&page={$page}'>{$page}</a> "; } $linkPage.=" {$this->page} "; for($i=1; $i<=$inum; $i++){ $page=$this->page+$i; if($page<=$this->pageNum) $linkPage.=" <a href='{$this->uri}&page={$page}'>{$page}</a> "; else break; } return $linkPage; } private function next(){ $html=''; if($this->page==$this->pageNum) $html.=''; else $html.=" <a href='{$this->uri}&page=".($this->page+1)."'>{$this->config["next"]}</a> "; return $html; } private function last(){ $html=''; if($this->page==$this->pageNum) $html.=''; else $html.=" <a href='{$this->uri}&page=".($this->pageNum)."'>{$this->config["last"]}</a> "; return $html; } private function goPage(){ return ' <input type="text" onkeydown="javascript:if(event.keyCode==13){var page=(this.value>'.$this->pageNum.')?'.$this->pageNum.':this.value;location=/''.$this->uri.'&page=/'+page+/'/'}" value="'.$this->page.'" style="width:25px"><input type="button" value="GO" onclick="javascript:var page=(this.previousSibling.value>'.$this->pageNum.')?'.$this->pageNum.':this.previousSibling.value;location=/''.$this->uri.'&page=/'+page+/'/'"> '; } function fpage($display=array(0,1,2,3,4,5,6,7,8)){ $html[0]=" 共有<b>{$this->total}</b>{$this->config["header"]} "; $html[1]=" 每頁顯示<b>".($this->end()-$this->start()+1)."</b>條，本頁<b>{$this->start()}-{$this->end()}</b>條 "; $html[2]=" <b>{$this->page}/{$this->pageNum}</b>頁 "; $html[3]=$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; }} 希望本文所述對大家基于yii框架的PHP程序設計有所幫助。
