Re: [fw-general] ZF 1.6 + Dojo xhrPost

You know what? Ignore that.. I'm severely under slept and over, erm, drank.

You'll want to call this:
$this->_helper->layout->disableLayout();

If you call:
    $this->_helper->viewRenderer->setNoRender(true);
From somewhere in your controller it will not render anything unless explicitly asked to; which in your case, you do with your call to the render() method on the action controller. But, setting this flag will not render the layout.

Hi there to all first post, so go easy on the newbie :-)

I've done PHP for several years, and a bit of AJAX, though a while ago
(cpaint anyone?). New to ZF and Dojo. Trying to get a simple xhrPost to work 
right and having issues - not sure if it's ZF or Dojo.
When my ajax cal lis returned - it adds in the entire layout to the response div instead of just the partial. Is there a way to just render the partial 
and have that inserted? I think this is something I need to do in the
controller so that the entire layout is not rendered - just the view.
Perhaps something with named segments?

MVC Application

Controller:
    public function editajaxAction(){
        switch($this->_getParam('formType')){
            case "addPlantUse":
                //Insert use data for the plant into the rel table
                Zend_Loader::loadClass('PlantsPlantUses');
                $useObject = new PlantsPlantUses();
                $data = array(
                    "plantID" => $this->_getParam('plantID'),
                    "useAbbreviation" => $this->_getParam('plantUse'));
                $useObject->insert($data);
//Get new list of uses for this plant 
                $plant = new Plants();
                $plantRowSet = $plant->find($this->_getParam('plantID'));
                $plantRow = $plantRowSet->current();
                $plantUses = $plantRow->findManyToManyRowset('PlantUses',
'PlantsPlantUses');
//Add data to the view 
                                $this->view->useList =
$plantUses->toArray();
                $this->render('editPlantUsePartial'); break;
        }
    }
