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。
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。
