Phalcon: HMVC view not working - view

Question

I got a problem rendering nested view, here is what I'm trying to do
I changed your 'request' of HMVC (HMVC-GitHub or/and HMVC-Pattern) function into an Elements module
namespace Modules\Main\Libraries;
/**
* Elements
*
* Helps to build UI elements for the application
*/
class Elements extends \Phalcon\Mvc\User\Component
{
public function loadModule($path = '', $data = array()) {
$di = clone $this->getDI();
$dispatcher = $di->get('dispatcher');
$paths = explode('/', $path);
$data = is_array($data) ? $data : array($data);
// get controller name
if (isset($paths[0])) {
$controller = $paths[0];
}
// get action name
if (isset($paths[1])) {
$action = $paths[1];
}
// get params
if (isset($paths[2])) {
array_splice($paths, 0, 2);
$params = array_merge($paths, $data);
} else {
$params = $data;
}
if (!empty($controller)) {
$dispatcher->setControllerName($controller);
} else {
$dispatcher->setControllerName('index');
}
if (!empty($action)) {
$dispatcher->setActionName($action);
} else {
$dispatcher->setActionName('index');
}
if (!empty($params)) {
if(is_array($params)) {
$dispatcher->setParams($params);
} else {
$dispatcher->setParams((array) $params);
}
} else {
$dispatcher->setParams(array());
}
$dispatcher->dispatch();
$response = $dispatcher->getReturnedValue();
if ($response instanceof ResponseInterface) {
return $response->getContent();
}
return $response;
}
}
and I have 2 controllers:
namespace Modules\Main\Controllers;
class IndexController extends ControllerBase
{
public function indexAction()
{
$secondContent = $this->elements->loadModule('test/hello/json');
$this->view->setVar('secondContent', $secondContent);
}
}
and
namespace Modules\Main\Controllers;
use \Phalcon\Http\Response;
class TestController extends ControllerBase
{
public function indexAction()
{
}
public function helloAction($format='html', $param = 'empty')
{
$this->view->setVar('content', 'Hello this is test value "'.$param.'"');
$content = $this->view->getContent();
return (string)$content;
// return 'Hello this is test value "'.$param.'"';
}
}
my DI
$di['elements'] = function() {
return new \Modules\Main\Libraries\Elements();
};
Views files
IndexController::Index
<h1>Congratulations!</h1>
<p>You're now flying with Phalcon. Great things are about to happen!</p>
<p>Second content: {{ secondContent}}</p>
<p>HMVC: {{ elements.loadModule('test/hello/json', 'test') }}</p>
and HelloController::test
This is :: {{ content }}
expecting to get
Congratulations!
You're now flying with Phalcon. Great things are about to happen!
Second content: This is :: Hello this is test value "empty"
HMVC: This is :: Hello this is test value "test"
but it only rendering the HelloController (First call from IndexController::indexAction):
This is :: Hello this is test value "empty"
if I change IndexController::indexAction to
public function indexAction()
{
$secondContent = '';
$this->view->setVar('secondContent', $secondContent);
}
and TestController::helloAction to
public function helloAction($format='html', $param = 'empty')
{
$this->view->setVar('content', 'Hello this is test value "'.$param.'"');
$content = $this->view->getContent();
//return (string) $content;
return 'Hello this is test value "'.$param.'"';
}
the result that i get is (Second content is empty):
Congratulations!
You're now flying with Phalcon. Great things are about to happen!
Second content:
HMVC: Hello this is test value "test"
Any solution to solve this ?
Thanks,

Phalcon have built-it modules feature, you dont have to built your own module loader, you just need create module bootstrap that extend ModuleDefinitionInterface.
Just take a look this sample from phalcon multi module
https://github.com/phalcon/mvc/tree/master/multiple
this example below is taken from link above, This contain module bootstrap code.
<?php
namespace Multiple\Frontend;
class Module
{
public function registerAutoloaders()
{
$loader = new \Phalcon\Loader();
$loader->registerNamespaces(array(
'Multiple\Frontend\Controllers' => '../apps/frontend/controllers/',
'Multiple\Frontend\Models' => '../apps/frontend/models/',
));
$loader->register();
}
/**
* Register the services here to make them general or register in the ModuleDefinition to make them module-specific
*/
public function registerServices($di)
{
//Registering a dispatcher
$di->set('dispatcher', function () {
$dispatcher = new \Phalcon\Mvc\Dispatcher();
//Attach a event listener to the dispatcher
$eventManager = new \Phalcon\Events\Manager();
$eventManager->attach('dispatch', new \Acl('frontend'));
$dispatcher->setEventsManager($eventManager);
$dispatcher->setDefaultNamespace("Multiple\Frontend\Controllers\\");
return $dispatcher;
});
//Registering the view component
$di->set('view', function () {
$view = new \Phalcon\Mvc\View();
$view->setViewsDir('../apps/frontend/views/');
return $view;
});
$di->set('db', function () {
return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
"host" => "localhost",
"username" => "root",
"password" => "secret",
"dbname" => "invo"
));
});
}
}
you can load module using this code below
$app = new \Phalcon\Mvc\Application();
$app->registerModules(array(
'frontend' => array(
'className' => 'Multiple\Frontend\Module',
'path' => '../apps/frontend/Module.php'
),
'backend' => array(
'className' => 'Multiple\Backend\Module',
'path' => '../apps/backend/Module.php'
)
));
