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：

public function actionIndex(){  $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  $page=new Page($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/** * 分页类，以组件形式存在于componnets文件中 */class Page {  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   * $listRows   */  public function __construct($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();   $fpage='';   foreach($display as $index){    $fpage.=$html[$index];   }   return $fpage;  }}
