ProcessWire - Rendering Funktionen

In den Template Strategiene sind einige Methoden beschrieben wie man Seiten in ProcessWire rendern kann. PW stellt aber auch einige Funktionen bereit, mit denen man Dateien oder Seiten direkt rendern kann. Diese arbeiten auch gut mit dem WireCache zusammen. So kann man Teile der Ausgabe rendern und gleich Cachen.

Functions

$files->render $page->render

Snippets

$content .= $files->render('teasers', ['items' => $pages->find("template=article")]);

Check if File is called directly or via wireRenderFile

Is there a way to check in my included template file if this child page is called directly, or whether it has been included from somewhere else? A simple check, so I can use the template in both scenarios (stand-alone view for just this page, or in cases I use wireRenderFile somewhere else). Right now I am passing the child page's ID like this:

wireRenderFile('my_template', array('pid' => $child->id)); And in my_template, to access it's own page fields, etc. I use

$thisPage = pages()->get($pid);
$myField = $thisPage->foo; // etc.

Is that the way to go, or do I overlook something obvious?

d'oh of course, it's as simple as:

if(isset($pid)) {
   $thisPage = pages()->get($pid); // we get called with wireRenderFile
} else {
   $thisPage = $page; // business as usual
}
