thanks for your help on this.
I'm trying to get this going, but not having any luck at all, especially
seeing as I haven't used json with zend yet.
I'm getting this error in my controller file.
Method "encodeJson" does not exist and was not trapped in __call()
public function _prepareautocompletion($data) {
$items = array();
foreach ($data as $key => $value) {
$items[] = array('label' => $value, 'name' => $value, 'key' =>
$key);
}
$final = array(
'identifier' => 'key',
'items' => $items,
);
return $this->encodeJson($final);
}
this is my autocompleteAction in CategoryController.php
function autocompleteAction ()
{
$this->getHelper('viewRenderer')->setNoRender();
$request = $this->getRequest();
$category_id = (int)$this->_request->getParam('category_id');
$race = new Race();
$races = $race->getCategoryRaces($category_id); // function to
output all
races
$this->view->races = $this->_prepareautocompletion($races);
}
Ok, now theres a couple things here i'm unsure of.
Firstly because this is setup with the first select box not populated
because it is expecting data from a data store, how am I to pass this info
into the json request. I'm sure I'm way off track with this one.
And Second, why am I getting the json error. Do I need to set something up
before hand for this to work.
thanks
