yii?CDbCriteria

[qq_20610429]

选择 Date Form 和 Date To,点 Search按钮,会查询出这两个日期间的数据

  public function search() {
        $criteria = new CDbCriteria;

        if(isset($_GET['date1'])&&isset($_GET['date2'])){
            $criteria->addBetweenCondition('news_date',$_GET['date1'], $_GET['date2']);
        }
        //这个功能已经实现
        //现在的问题是:如果用户只选择了 Date Form,就显示Date Form 这个日期之后的所有数据
       // 只选择了 Date To就显示Date To 这个日期之前的所有数据                      
        return new CActiveDataProvider($this, array(
            'criteria' => $criteria,
        ));
    }

给你代码,几乎差不多

public function failureCat()
        {
                $criteria = new CDbCriteria;
                $criteria->compare('t.failItem', $this->failItem);
                $criteria->compare('logInfo.logProcess', $this->failStation);
                $criteria->compare('logInfo.logUpdate', '>=' . $this->dateToDatetime($this->startDate, 1));
                $criteria->compare('logInfo.logUpdate', '<=' . $this->dateToDatetime($this->endDate));
                $criteria->with = array('logInfo');
                return new CActiveDataProvider('TestLogFail', array(
                    'pagination' => array(
                        'pageSize' => Yii::app()->params['pageSize'],
                    ),
                    'criteria' => $criteria,
                    'sort' => array(
                        'defaultOrder' => 'logInfo.logUpdate desc',
                    ),
                ));
        }
