\Phalcon\Mvc\View's setContent() not working in action

I have a question about how the \Phalcon\Mvc\View works. This class has a setContent() method, yet the content set with it won't be part of the output of $this->getContent() - neither in views/example/overview.phtml nor views/index.phtml. Shouldn't foobar show up in one of those views?

Use-Case: I have different HTML codes for some contents, saved in a database. Those codes should be setable as the content for overviewAction (and some other actions in different controllers) and I don't want to create view files for all those actions, yet the content should be included in/be part of the main layout. That's why simply returning the content won't work.

ExampleController.php

class ExampleController extends \Phalcon\Mvc\Controller {
    public function overviewAction () {
        //This doesn't work, too:
        //$this->view->disableLevel([\Phalcon\Mvc\View::LEVEL_ACTION_VIEW => true]);
        $this->view->setContent('foobar');
    }
}

index.php:

$di->setShared('view', function() use ($events_manager, $di) {
    $view = new \Phalcon\Mvc\View();

    //Disable layout-level
    $view->disableLevel([\Phalcon\Mvc\View::LEVEL_LAYOUT => true]);

    //Bind the EventsManager to the view component
    $view->setEventsManager($events_manager);

    $view->setVar('f', $di->get('filter'));

    return $view;
});

Hi @fabsn182 to render any view file what you want you have to use pick() method from the view to select them.

Tip: don't need set filter service in view because is already injected in DI and the view too. Then you can use filter in the view files.

// view.phtml
<h1>Hello <?=$this->filter->sanitize($userName, 'string')?></h1>

Good luck

I don't want to render any view for those actions. I want to set the content without having to create and/or pick a specific view file.

That's what the setContent() method is for, isn't it? Because returning anything from an action results in only that content being shown - without being wrapped with the layout file

//I am not setting the filter service, I am setting a shortcut ($f) for all views

Well you have to use response service for that


class SomeController extends \Phalcon\Mvc\Controller {
    public function indexAction() {
        return $this->response->setContent('hello world!')->send();     
    }
}

Please read what I wrote:

returning anything from an action results in only that content being shown - without being wrapped with the layout file

And that is an unwanted behaviour

I dont know what view->setContent() actually does, but this is working for me:

class ExampleController extends \Phalcon\Mvc\Controller {
    public function overviewAction () {
        echo 'foobar';
    }
}
<p>
<h1>Some content page</h1>
{{ content() }}
</p>

Result is

Some content page

foobar

so RTFM

Oh boi, calm your tits. There's nothing in the "manual" about that. Lajos Bencz's answer works but feels wrong. Echoing in a controller? Meh.
