Snippet to Select Chunks with Wayfinder

Over the last few years I have gotten more and more proficient with building complex, MODx Wayfinder calls to meet my development needs. I have found that if I spend a little extra time constructing my snippet calls I can create single calls that serve my purposes in multiple situations. While this is a satisfying process, once completed, it can be very frustrating to create and test these calls while taking up a lot of valuable time. It finally occurred to me recently that I could take an alternative approach.

Rather than trying to build one-size-fits-all Wayfinder calls, why not build a snippet that allows me to choose from very simple and specific calls dependent on criteria like template ID, document depth (Aaron Ladage’s Count Snippet) and whether the document is a folder or not. These are just examples that I used in my last site development. I imagine that you could use any available MODx variables for your snippet logic.

<?php
$TempId = $modx->documentObject['template'];
$CountLocation = $modx->runSnippet('Count');
$Folder = $modx->documentObject['isfolder'];

if ($TempId=="1" && $CountLocation=="0" && $Folder=="1") {
  $output="{{template1depth0folder1}}";
} else if ($TempId=="1" && $CountLocation=="0" && $Folder=="0") {
  $output="{{template1depth0folder0}}";
} else if ($TempId=="1" && $CountLocation=="1" && $Folder=="0") {
  $output="{{template1depth1folder0}}";
}else if ($TempId=="1" && $CountLocation=="2" && $Folder=="0") {
  $output="{{template1depth2folder0}}";
} else if ($TempId=="2") {
  $output="{{template2}}";
} else {
   $output="{{defaultNavigation}}";
}

return "$output";
?>
