[NFR] Fetch current View render level in the events attached to Phalcon\Mvc\View

[temuri416]

1. Phalcon\Mvc\View supports hierarchical view rendering:

Main View -> Controller View -> Action View

1. Phalcon\Mvc\View emits event view to which I can attach a listener:

$eventsManager->attach('view', function($event, $view) {
    if ('afterRenderView' == $event->getType()) {
        // Append length of rendered content.
        $content = $view->getContent();
        $content .= PHP_EOL . '/* Content length: ' . strlen($content) . 'b */' . PHP_EOL;
        $view->setContent($content);
    }
});

I want to be able to retrieve current View::LEVEL_ACTION_* in my event handler to be able to branch necessary action depending on the combination of current level in hierarchy and type of event:

$eventsManager->attach('view', function($event, $view) {
    if ('afterRenderView' == $event->getType() && $view->getCurrentLevel() == View::LEVEL_LAYOUT) {
        // Append length of rendered content.
        $content = $view->getContent();
        $content .= PHP_EOL . '/* Content length: ' . strlen($content) . 'b */' . PHP_EOL;
        $view->setContent($content);
    }
});

Feature Request

Implement $view->getCurrentLevel().

I think what you have implemented is a getter for the value set by:

\Phalcon\Mvc\View::setRenderLevel()

In this ticket I was asking for a getter method for current level that's being rendered by the View.

Do you think that can also be done?

Thanks!

Confirmed - works as expected. Thank you!
