A few days ago i took a look at the proposal, its a good implementation for
the view object, but unfortunately i couldn't use my front controller
plugins - like ACL checking - without reinventing.
Another issue for me was merging the injected data for the view object. i
dont know how far the view enhanced proposal goes, i wanted to get the view
and native data of the view and individualy replace the views data by the
view/widget caller. i also implemented a layout wrapper. the widget helper
looks like:
class RF_View_Helper_Widget extends RF_View_Helper
{
public static $passThroughParamsRecursive = true;
/**
* This method returns the response of a virtual subrequest.
*
* @author Markus Siebeneicher <[EMAIL PROTECTED]>
*
* proxies to [EMAIL PROTECTED] widgetUri()}
*
* @param string $action
* @param string $controller
* @param string $module
* @param array $params URI Parameter aka Query Params
* @param array $passThroughParams params for the front controller
* @return Zend_Controller_Response_Http
*/
public static function widget($action, $controller = NULL, $module =
NULL, $params = array(), $passThroughParams = array())
{
return self::widgetUri(RF_Helper::makeZendUri($action,
$controller,
$module, $params, $passThroughParams));
}
/**
* This method returns the response of a virtual subrequest.
*
* @author Markus Siebeneicher <[EMAIL PROTECTED]>
*
* @todo widget output/errors handeln
*
* @param string|Zend_Uri $uri
* @param array $passThroughParams params for the front controller
* @return Zend_Controller_Response_Http
*/
public static function widgetUri($uri, $passThroughParams = array()) {
$frontParent = RF_Controller_Front::getInstance();
if(self::$passThroughParamsRecursive === true)
if(count((array)
$frontParent->getRuntimeParam("widgetPassThroughParams")) > 0)
$passThroughParams =
self::mergePassThroughParams(
$passThroughParams,
$frontParent->getRuntimeParam("widgetPassThroughParams")
);
$front = RF_Controller_Front::initFrontController($frontParent);
$front->setRuntimeParam("widgetPassThroughParams",
$passThroughParams);
$request = new Zend_Controller_Request_Http($uri);
$response = new Zend_Controller_Response_Http();
ob_start();
$t1 = microtime(true);
$front->dispatch($request, $response);
$t2 = microtime(true);
Zend_Registry::getInstance()->rfLogger->log("Time used to dispatch
widget(". $front->getRequest()->getRequestUri() ."): ". ($t2-$t1),
Zend_Log::DEBUG);
//$front->getResponse()->setBody(ob_get_contents());
ob_end_clean();
RF_Controller_Front::destroyLastInstance();
//unset($front);
return $response;
}
/**
* hier werden zwei arrays gemerged, die elemente werden dem major vom

* wenn der key im major noch nicht existiert
*
* @author Markus Siebeneicher <[EMAIL PROTECTED]>
*
* @param array $majorParams
* @param array $minorParams
* @return array
*/
private static function mergePassThroughParams($majorParams,
$minorParams)
{
//print_r($minorParams);
//print_r($majorParams);
foreach($minorParams AS $_key => $_value) {
if(isset($majorParams[$_key])) {
if(is_array($majorParams[$_key]) &&
is_array($minorParams[$_key])) {
$majorParams[$_key] =
self::mergePassThroughParams($majorParams[$_key], $minorParams[$_key]);
}
} else {
$majorParams[$_key] = $_value;
}
}
return $majorParams;
}
