Simple snippet (output filter) for MODX Revolution related items. Call as [[snippetname? &tpl=`chunkname` &input=`[[*your-comma-delimited-id-tv]]`]]

gistfile1.php

<?php
if ($input == null) { return 'No relevant items found.'; }

  $tpl = $modx->getOption('tpl',$scriptProperties,null);
  if (($tpl === null) || (!$modx->getChunk($tpl))) { return 'No template found'; }

  $ids = explode (',', $input);
  foreach ($ids as $a => $key) {
    $document = $modx->getObject('modResource', array(
      'published' => 1,
      'id' => $key));
    if ($document) {
      $output[] = $modx->getChunk($tpl,$document->toArray());
    }
  }
  return implode(', ',$output);
?>

Did you select any items in your TV?

What do you get if you just output [[*relatedPages]] in your template or content?

Yep, have 4 items selected in the listbox.

When I just call the TV, I get a comma-delimited list of the ids I've chosen.

Hi Mark,

I've had a little look at this again this morning.

It seems that part of the snippet is working. When I remove &input, I get the 'No relevant items found' messgae, and when I remove &tpl, I get the 'No template found message.

It just won't display anything when I do include both the input and the template. I've tried altering the template to just display the id, or the pagetitle, but with no luck.

Any thoughts would be much appreciated!

I suspect you mistyped the chunk name.. It worked fine for me.

Updated the gist above with some better error reporting for chunks.
