I saw this on the old modx forum and I know there are probably a million different ways to do this. I thought this might help someone else down the road. Of course if anyone has a better way I am completely open to modify it!
<?php
/* ShowNav snippet
[[!NextPrev_Snip? &parents=`8,9,11` &chunk=`nextPrevChk`]]
*/
// input from snippet for parent ids
$parentIds = explode(',', $parents);
// get parent id
$parentId = $modx->resource->get('parent');
// if there is a match show chunk otherwise hide
if (in_array($parentId, $parentIds)) {
// get a custom chunk to output anything based on parent id
$output = $modx->getChunk($chunk);
}
return $output;
The chunk can be anything, I used a chunk to with the snippet [[pdoNeighbors]] “prev / next” buttons.
