Php Yii CDbCriteria将2个属性与单个值进行比较

嗨，我是yii的新手，目前正在从事一个项目，我在CDbCriteria方面遇到了问题

我的目标查询是：

title LIKE '$_GET['search']%' OR description LIKE '$_GET['search']%'

使用CDbCriteria compare是否有可能获得与此相同的结果

控制器操作：

public function actionClassifieds(){
    $model = new Classifieds('search');
    $model->unsetAttributes();
    if(isset($_GET['category'])){
        if( $_GET['category'] == 0 ){
            $model->classified_category_id = '';
        }else{
            $model->classified_category_id = $_GET['category'];
        }
    }
    if(isset($_GET['search'])){
        $model->title = $_GET['search'];
        $model->description = $_GET['search'];
    }
    $this->render('classifieds',array('model'=>$model));
}

我的模型：

public function search()
{
    // Warning: Please modify the following code to remove attributes that
    // should not be searched.

    $criteria=new CDbCriteria;

    $criteria->compare('classified_category_id',$this->classified_category_id);
    $criteria->compare('title',$this->title,true);
    $criteria->compare('description',$this->description,true);
    $criteria->compare('price',$this->price,true);
    $criteria->compare('timestamp',$this->timestamp);

    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
        'pagination'=>array(
            'pageSize'=>10,
        ),
    ));
}

尝试：

最好使用

Yii:：app（）->request->getParam（$var\u name）

已更新

$criteria->compare('classified_category_id',$this->classified_category_id);
$criteria->compare('price',$this->price,true);
$criteria->compare('timestamp',$this->timestamp);

$criteria->addCondition("title LIKE :t OR description LIKE :d");
$criteria->params[':t'] = $this->title;
$criteria->params[':d'] = $this->description;
