quarter ago
 
8 ) 6 months ago
- 
year ago

year+ ago
 
and it should be available at my advance search function.
here’s what i have at the moment ( I copied the function of the admin controller + view )
//controller
        public function actionAdvancecvsearch()
        {
            $model = new Wsrecruitcvhead('search');
            $model->unsetAttributes();
            if(isset($_GET['Wsrecruitcvhead'])){
                $model->attributes = $_GET['Wsrecruitcvhead'];
            }
                  $this->render('advancecvsearch',array(
                    'model' => $model,
                ));
       }
//model
        const LAST_DAY = 0;
        const LAST_3_DAYS = 1;
        const LAST_5_DAYS = 2;
        const LAST_WEEK = 3;
        const LAST_FORNIGHT = 4;
        const LAST_MONTH = 5;
        const LAST_QUARTER = 6;
        const LAST_6_MONTHS = 7;
        const LAST_YEAR = 8;
        const LAST_YEAR_BEYOND = 9;
/*

* how will I use the  data from the select option to solve it
