yii修改默认分页每页显示条数，修改排序

修改model中的search函数。增加pagination和sort。

 public function search() {  // @todo Please modify the following code to remove attributes that should not be searched.  $criteria=new CDbCriteria;  $criteria->compare('id',$this->id);  $criteria->compare('name',$this->name,true);  $criteria->compare('parent_id',$this->parent_id);  $criteria->compare('postcode',$this->postcode,true);  $criteria->compare('order',$this->order);  $criteria->compare('status',$this->status);  return new CActiveDataProvider($this, array(   'criteria'=>$criteria,   'pagination'=>array(    'pageSize'=>30, //代表每页显示30条信息   ),   'sort' => array(    'defaultOrder'=>'sort_order ASC, create_time DESC, id DESC',   ),  )); }
