		'select' => array(

                       

                        'Cot.*','d1.photo1')

                       ,

		

		'alias'=>'{{Cot}}',

		

        'condition'=>'status=1 AND re_id='.$id,

		'join'=>'LEFT JOIN details as d1 ON d1.id=re_id',

		

		)));

		$this->render('details',array(

			'dataProvider'=>$dataProvider,


		

		

		));

echo CHtml::encode($data->re_id);
