The onChange url needs to send back a Json-encoded response- basically an
array of rows containing name-value pairs passed to Zend_Json_Encoder.
In my "data" controller I have a generic "lookup" action. All you need is a
model that can return rows of city names and id's.
public function lookupAction()
{
$tableName = $this->_request->getParam('table');
$filterName = $this->_request->getParam('filterName');
$filterValue = $this->_request->getParam('filterValue');
if (empty($tableName))
{
return;
}
// TODO: Should be generic for all lookup tables
if ('city' === $tableName) {
$_model = new NAME_OF_YOUR_CITY_MODEL();
// getLookup just returns the rows that match the filter, in this case a
countryId
$data = $_model->getLookup($filterName, $filterValue);
if (null !== $data) {
$items = array();
foreach ($data as $row) {
$items[] = array('label' => $row->name, 'name'
=> $row->name,
'key' => $row->cityId);
}
$final = array(
'identifier' => 'key',
'items' => $items,
);
echo Zend_Json_Encoder::encode($final);
}
}
}
