Overcome caching limitation when you call a snippet inside another snippet

Uncached snippets might put a big load on you server. To solve this problem we'll have to create a new snippet and make use of runSnippet() API.

<?php
$parentparent = $modx->runSnippet("ParentParent");
$wayfinderOutput = $modx->runSnippet("Wayfinder", array('startId' => $parentparent));
return $wayfinderOutput;
?>

Because Wayfinder does not know how to get the second level parent ID of the current document, I had to create my own snippet: ParentParent. You can download this snippet here.

For readability sake, I saved the output of the ParentParent into a variable and then used it in the Wayfider call.

Not so hard! Leave a message if you know other solutions.

Nice one! Typo in the title - "cashing" should be "caching"
