For JSON exchange I doing special module 'json' named.
Addition I create "config" folder for "json" module and create
"view.yml" whithout template.
My actions sample:
public function executeNewChart(sfWebRequest $request) {
$retData = array();
/*
only ajax request
*/
if ($request->isXmlHttpRequest()) {
/* any manipulation data */
$this->getUser()->setAttribute('statYear', $request-
>getParameter('statChartType', 'p3') );
$retData['statYear'] = $this->getUser()->getAttribute
('year', date('Y', time() ) );
$retData['statView'] = $this->getUser()->getAttribute
('statView', 'toCommon');
$retData['statTypeService'] = $this->getUser()-
>getAttribute('statTypeService', 'hosting');
$retData['statChartType'] = $request->getParameter
('statChartType'); //$newReport->createStatData($this->getUser()-
>getAttribute('statTypeService'));
$newReport = new statHarvester( $this->getUser()-
>getAttribute('statTypeService'), $request->getParameter('year'));
$retData['newReport'] = '';
/* create JSON*/
$retData = json_encode( $retData );
/* Prepare JSON data */
$this->renderText( $retData );
}
// without template and RETURN
return sfView::NONE;
}
You remember, if use "dev" env - Symfony send add information, can
destroy JSON data - use "PROD" dev for testing and debug.
Sorry for my english, but I think what my understand.
