I create my own tv Input Tag and tried to use getresources but can not get it to run hope someone can help.

$this->xpdo->lexicon->load('tv_widget');

$properties = array(
	'tpl'=>'schauspielerJsonList',
	 'parents'=>'2'
);

$jsonString = $modx->runSnippet('getResources', $properties);

//$jsonString = '{"name":"Arnold","id":"123"}';

$elements = json_decode($jsonString);

return 'elem: '.$jsonString;

I create a chunk that should be field from get resources in json format, than decode it i work with it, but getresources give no data back. Do i need to run the ’runSnippet’ on another way for a custom TV INput?

Would probably help to see the "schauspielerJsonList" template.

And why wouldn’t you just use the Resource list input type? That will create a dropdown list of all resource under the ID you specify in the input options.

Here is the code of the ’schauspielerJsonList’ chunk

{"name":"[[+pagetitle]]","id":"[[+id]]"}

I need it because i want to make a TV input where i can choose an Movie Actor and then write is movie role all in one TV. If i use the Resource Input Tag i can only choose the actor.

I think it’s easier to just use MODX/xPDO objects instead..

$this->xpdo->lexicon->load('tv_widget');

$parent = $modx->getObject('modResource',2);
$children = $parent->getMany('Children');
if (empty($children)) { return; }

$list = array();
foreach ($children as $child) {
  $list[] = array(
    'name' => $child->get('pagetitle'),
    'id' => $child->get('id'));
}

return $modx->toJSON($list);

Maybe I’m misunderstanding you, but I think you’re making this more complicated than it needs to be.

You send getResources() the selection and sorting criteria and the name of the Tpl chunk (with placeholders in it for the fields). getResources returns the HTML output for the screen.

You want something more like this:

<?php
$this->xpdo->lexicon->load('tv_widget');

$properties = array(
	'tpl'=>'schauspielerJsonList',
	 'parents'=>'2'
);

$local_where = array(
      'name'=>'Arnold',
      'id'=> '123',
};

$properties['where'] = $modx->toJSON($local_where);

return 'Elem: ' . $modx->runSnippet('getResources', $properties);

Obviously, this code can be shortened. I spread it out to make it easier to see what’s happening.
