Yii CDbCriteria compare 2 attributes to a single value - php

Question

Hi I am new to yii and I am currently working on a project and I am having trouble with CDbCriteria.
My target query is:
title LIKE '$_GET['search']%' OR description LIKE '$_GET['search']%'
Is it possible to attain same result like this using CDbCriteria compare?
Controller action :
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));
}
My model:
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,
),
));
}

Answer 1

Try:
$criteria->condition = "title LIKE :t OR description LIKE :d";
$criteria->params = array(
':t' => trim( Yii::app()->request->getParam('search') ).'%',
':d' => trim( Yii::app()->request->getParam('search') ).'%');
Better using Yii::app()->request->getParam($var_name)
UPDATED
$criteria->compare('classified_category_id',$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;
