Placeholders in TV Input Option

getOption() first checks for a User Setting, then a Context Setting, then a System Setting. I think the problem is that the current context is 'mgr' and there's no context setting there.

The best solution would probably be @EVAL global $modx; return $modx->runSnippet();
with a custom snippet to generate the output.

The resource's context is available with $resource->get('context_key');

The problem is that AFAIK, you can't use $modx->resource reliably at that point -- only in the front end.

Ok,I think I know how to do it. Last thing what I need is:
Any function how to get context_key from documentId? Can't find.
Thanks a lot.

$doc = $modx->getObject('modResource', $documentId);
if ($doc) {
    $contextKey = $doc->get('context_key');
}

You can leave out the 'if' if you're absolutely sure that the documentId is valid. If it's not, the get() will throw a PHP error.

SOLVED.

I needed just something like that to generate a list in the TV when editing a resource.

@SELECT pagetitle, id FROM modx_site_content WHERE parent=[[++shop]]

Unfortunately this simple code doesn't work.

So the solution is:

TV input option

@EVAL $documentId = $modx->resource->get('id'); return $modx->runSnippet('getCheckboxes',array('documentId' => $documentId, 'option' => 'shops'));

Snippet getCheckboxes

<?php
$doc = $modx->getObject('modResource', $documentId);
if ($doc) {
    $contextKey = $doc->get('context_key');
    $modx->switchContext($contextKey);
    $resId = $modx->getOption($option);
}


$output = $modx->runSnippet (
  "getResources" , array(
     "tpl" => "checkboxTpl", 
     "parents"=> $resId,      
     "limit"=>"80",
     "depth"=>"0",
     "sortby"=>"menuindex",
     "sortdir"=>"ASC"   
     ) 
);
return $output;

Thank you very much Bob and Sottwell!

You might want to do this, especially if the context switch causes any trouble:

$oldContext = $modx->context->get('key);
$modx->switchContext($contextKey);
$resId = $modx->getOption($option);
$modx->switchContext($oldContext);

Here's another (maybe better) alternative that would keep you from having to switch contexts at all. This will get the Context Setting directly:

$contextKey = $doc->get('context_key');
$context = $modx->getObject('modContext', array('key' => $contextKey));
$resId = $context->getOption($option);
