[fw-mvc] Fetch data to Json conversion issue

Dear Sir,

 

 

Hello ! Well I am calling ajax request from my javascript function which in turn is called from dojo.combobox onChange event. I want to return Json output to this javascript from my action. It works well on hard coded array $arr but does not work with $data which has actual dynamic table data.

 

 

      public function gettaskAction()

      {

            $taskhead = new Taskhead();

            $data= $taskhead->fetchAll();

            $arr = array (identifier=>'name',

                  items=>array(

                  array('name'=>'Bidding', 'label'=>'Bidding'),

                  array('name'=>'Response-proposal    ', 'label'=>'Response-proposal')

               )

            );

            $this->_helper->json($data, array('enableJsonExprFinder' => true));          

      }

 

If I put above $arr in place of $data in json call, it works well and populate my comboxbox but putting $data it does not work, might be not proper json format is converted.

 

Please guide me on this.

 

Thanks in Advance !
