Using Tokeninput extension in Yii fremwork.

1. Download Tokeninput extension for Yii from here.

2. Extract it in your project under protected/extensions/tokeninput
3. Add extension to your main.php file

'import' => 'application.extensions.tokeninput',
4. Now change your view code

 <?php $this->widget('ext.tokeninput.TokenInput', array(  
           'model' => $person,  
           'attribute' => 'name',  
           'id' =>'director',  
           'url' => array('person/personsearch'),  
           'options' => array(  
             'allowCreation' => true,  
             'preventDuplicates' => true,  
             'resultsFormatter' => 'js:function(item){ return "<li><p>" + item.name + "</p></li>" }',  
             'theme' => 'facebook',  
           )  
         )); ?>  

This will give you comma saprated id of persons e.i. 22,33,44
5. here is your controller code to get the data from database. I am using Mysql database

 public function actionPersonsearch($q){  
         $term = trim($q);  
         $response = array();  
         $criteria=new CDbCriteria;  
         $criteria->alias = "PE";  
         $condition = "PE.name like '%" . $term . "%'";  
         $criteria->condition = $condition;  
         $dataProvider = new CActiveDataProvider(get_class(Person::model()), array(  
         'criteria'=>$criteria,'pagination'=>false,  
         ));  
      $persons = $dataProvider->getData();  
      $person_list = array();  
      foreach($persons as $person) {  
       $person_list[] = array(  
              'name'=>$person->name,  
              'id'=>$person->id,  
              );  
      }  
         $response = CJSON::encode($person_list);  
         echo $response;  
     }
