Yii框架实现数据分页及排序的例子

class PostController extends Controller
{
    function actionIndex()
    {
        $criteria = new CDbCriteria();
        $count=Post::model()->count($criteria);
        $pages=new CPagination($count);
 
        // elements per page
        $pages->pageSize=5;
        $pages->applyLimit($criteria);
 
        // sorting
        $sort = new CSort('Post');
        $sort->attributes = array('id', 'title',);
        $sort->applyOrder($criteria);
 
        $models = Post::model()->findAll($criteria);
 
        $this->render('index', array(
            'models' => $models,
            'pages' => $pages,
            'sort' => $sort,
        ));
    }
}

link('id')?>

link('title')?>

foreach($models as $model):?>
   
1. 
          

   id?> - title?>

            group by remitdate
            order by remitdate desc";

        $result = Yii::app()->db->createCommand($sql)->query();
        $pages=new CPagination($result->rowCount);
        $pages->pageSize=2;
        $pages->applyLimit($criteria);
        $result=Yii::app()->db->createCommand($sql." LIMIT :offset,:limit");
