Yii使用CPagination分页

 

 

public function actionIndex()
    {
        $criteria = new CDbCriteria();
        $criteria->order = 'createtime desc';
        $count = Article::model()->count($criteria);

        $pager = new CPagination($count);
        $pager->pageSize = 10;
        $pager->applyLimit($criteria);

        $artList = Article::model()->findAll($criteria);
        $this->render('index',array('pages'=>$pager,'list'=>$artList));
    }

 

在视图中代码如下：

<div id="pager">
    php

    $this->widget('CLinkPager',array(
        'header'=>'',
        'firstPageLabel' => '首页',
        'lastPageLabel' => '末页',
        'prevPageLabel' => '上一页',
        'nextPageLabel' => '下一页',
        'pages' => $pages,
        'maxButtonCount'=>13
        )
    );
    ?>
    div>

ps：一般写法：

 

$criteria = new CDbCriteria;
$count = DnOnline::model()->count($criteria);

$pages = new CPagination($count);
$pages->pageSize = 5;
$pages->applylimit($criteria);

$model = DnOnline::model()->findAll($criteria);

CDB写法：

    $criteria = new CDbCriteria;
    $sql = "SELECT * FROM USER";
    $model= Yii::app()->db->createCommand($sql)->queryAll();
    $pages = new CPagination(count($model));
    $pages->pageSize = 4;
    $pages->applylimit($criteria);

    $model=Yii::app()->db->createCommand($sql." LIMIT :offset,:limit");
    $model->bindValue(':offset', $pages->currentPage*$pages->pageSize);
    $model->bindValue(':limit', $pages->pageSize);
    $model=$model->queryAll();

$criteria=new CDbCriteria();
            $result = Yii::app()->db->createCommand($sql_do)->query();
           $pages=new CPagination($result->rowCount);
          $pages->pageSize=2;
            $pages->applyLimit($criteria);
          $result=Yii::app()->db->createCommand($sql_do." LIMIT 2");
           $result->bindValue(':offset', $pages->currentPage*$pages->pageSize);
         $result->bindValue(':limit', $pages->pageSize);
         $list=$result->query();

在yii中有自带的分页方式，通过cgridview等

mongo扩展使用统一方法

    /**
     * 分页查询
     * @param DBModel           $model      数据所在表的模型对象
     * @param EMongoCriteria    $criteria   查询过滤器
     * @param int               $size       每页记录数，默认10
     * @return 包含查询结果[rs]和分页信息[pages]的数组
     */
    public function makePage($model, $criteria=array(), $size=10){
        $count = $model->count($criteria);

        //创建分页数据并加入到查询器中
        $pager = new CPagination($count);
        $pager->pageSize = $size;
        $criteria->offset($pager->getCurrentPage()*$pager->getPageSize());
        //无法使用$pager->applyLimit($criteria);代替
        $criteria->limit($pager->getPageSize());

        //获取用户数据
        $rs = $model->findAll($criteria);
        return array('rs'=>$rs,'pages'=>$pager);
    }
