Multiselect TV: Only show resources from actual context

General
1

Hi,
I have a multiselect-TV hosting resources from two parents which are in two different contexts:

@SELECT pagetitle, id FROM modx_site_content WHERE parent IN (2,4)

parent #2 is in context web
parent #4 is in context lang

I would like to restrict my multiselect-TV to only show the resources from the actual context like you can do with a resourcelist-TV using limitRelatedContext. How is this possible?

Thanks in advance.

So why don’t you just use a resourcelist-TV then?

With the settings:

  • Parents = 2,4
  • Depth = 1
  • Include Parents = No
  • Limit to Related Context = Yes

With a multiselect-TV you probably have to use a @CHUNK binding (instead of @SELECT).

For example use this in the field Input Option Values.

@CHUNK listResources

Then create a chunk listResources that calls a snippet.

[[listResources]]

Then create a snippet listResources with code like this to create the list.

<?php
$current_ctx = $modx->resource->get('context_key'); //context of current resource

$q = $modx->newQuery('modResource', array('parent:IN' => array(2,4), 'context_key' => $current_ctx, 'deleted' => 0));
$q->select(array('id','pagetitle'));
$q->sortby('menuindex','ASC');
$resources = $modx->getCollection('modResource', $q);
$output = array();
foreach ($resources as $resource) {
   $output[] = $resource->get('pagetitle') . '==' . $resource->get('id');
}
return implode('||',$output);

Because I want to select multiple resources and a resourcelist-TV is a single-select dropdown afaik. Or am I wrong here?

Thank you for your code, trying it atm.

In this case you probably can use the SuperBoxSelect extra.

Never heard of that, will try it out.
Your code works perfectly fine, thank you very much!

SuperBoxSelect has some advantages over a multiselect-TV.

It uses paging (with AJAX) which is great if you have a lot of resources to choose from and you can also reorder the selected items which is neat.

I see. Will definitely check out SuperBoxSelect, thanks for the tip and your code, @halftrainedharry !
