Zend framework Zend Dojo筛选选择仅返回一个值

大家好，请告诉我为什么下面的代码只返回单个值2，巴斯

来自控制器的自动完成操作

  public function groomappointserviceAction()
   {

    $this->_helper->layout->disableLayout();
    $this->getHelper('viewRenderer')->setNoRender(true);

    // get a list of all grooming services IDs and related procedures
   $gqry= Doctrine_Query::create()
   ->select('g.groomServicesID AS iden , p.groomprocedure AS name')
   ->from('PetManager_Model_Groomservices g')
   ->leftJoin('g.PetManager_Model_Groomprocedures p');
   $result = $gqry->fetchArray();

   //generate and return JSON string 
    $data = new Zend_Dojo_Data('iden',$result);
    echo $data->toJson();
  }

我表格中的筛选选择

  // Create a autocomplete select input for the grooming
    $gservice = new Zend_Dojo_Form_Element_FilteringSelect('gapmtService');
    $gservice->setLabel('Proceedure');
            $gservice->setOptions(array(
            'autocomplete' => true,
            'storeID'   => 'groomappointserviceStore',
            'storeType' => 'dojo.data.ItemFileReadStore',
            'storeParams' => array('url' => "/groomappointments/appointment/groomappointservice"),
      'dijitParams' => array('searchAttr' => 'name')))
        ->setRequired(true)
        ->addValidator('NotEmpty', true)
        ->addFilter('HTMLEntities')            
        ->addFilter('StringToLower')        
        ->addFilter('StringTrim');

当MySQL中相同的（我相信）查询返回时

mysql> select g.groomservicesid AS iden , p.groomprocedure as name
     -> from groomservices AS g LEFT JOIN groomProcedures AS p
     -> on g.groomProcedure = p.groomProceduresID;
 +------+--------------------------+
 | iden | name                     |
 +------+--------------------------+

 |    7 | Bath                     |
 |    8 | Bath                     |
 |    9 | Bath                     |

 |    4 | Nail Clip                |
 |    5 | Nail Clip                |
 |    6 | Nail Clip                |

 |   11 | Bath Brush               |
 |   12 | Bath Brush               |

好的，我已经把代码改成下面的代码，把它分类了。我不知道为什么它现在能工作，因为我之前试过这个，但它不起作用

我的自动完成动作

public function groomappointserviceAction()
{

    $this->_helper->layout->disableLayout();
    $this->getHelper('viewRenderer')->setNoRender(true);

   // get a list of all grooming services IDs and related procedures
   $gqry= Doctrine_Query::create()
       ->select('g.groomServicesID, p.groomprocedure AS name')
       ->from('PetManager_Model_Groomservices g')
      ->leftJoin('g.PetManager_Model_Groomprocedures');
   $result = $gqry->fetchArray();

  //generate and return JSON string 
  $data = new Zend_Dojo_Data('groomServicesID',$result);
  echo $data->toJson();
}

我表格上的过滤器选择

  // Create a autocomplete select input for the grooming
    $gservice = new Zend_Dojo_Form_Element_FilteringSelect('gapmtService');
    $gservice->setLabel('Proceedure');
    $gservice->setOptions(array(
      'autocomplete' => true,
      'storeID'   => 'groomappointserviceStore',
      'storeType' => 'dojo.data.ItemFileReadStore',
      'storeParams' => array('url' => "/groomappointments/appointment/groomappointservice"),
      'dijitParams' => array('searchAttr' => 'name')))
        ->setRequired(true)
        ->addValidator('NotEmpty', true)
        ->addFilter('HTMLEntities')            
        ->addFilter('StringToLower')        
        ->addFilter('StringTrim');

有人知道我在哪里搞砸了吗？
