Modx Revolution SlideshowManager - list all albums

Question

I am trying to list all albums that are available in the SlideshowManager Addon in a TV List.

To do so I am trying to make a snippet for that like it is described here https://github.com/jgulledge19/Slideshowmanager/blob/master/core/components/slideshowmanager/processors/mgr/album/getlist.php

But I don't get any results. Here is what I have so far.

The TV

@eval return $modx->runSnippet('jgSlideshowAlbum__getList',array());

My Snippet

<?php
// create query
$query = $modx->newQuery('jgSlideshowAlbum');
// $query->limit(10);
$query->where(array('title:=' => 'Main Slideshow'));
// get albums
$albums = $modx->getIterator('jgSlideshowAlbum',$query);
// return result as list
foreach($albums as $album) {
die(print_r($album->toArray()));
}

For the moment I just want some output so I die() if there was found something.

EDIT/UPDATE

Here the output of the Errorlog

Answer 1

How about to call the original processor in your snippet?

<?php

$limit = 0;
$sort = 'id';
$dir = 'ASC';
$query = '';

$properties = array(
    "limit" => $limit,
    "sort" => $sort,
    "dir" => $dir,
    "query" => $query
);

$slideshowmanagerPath = $modx->getOption('slideshowmanager.core_path',null,$modx->getOption('core_path').'components/slideshowmanager/');

$modx->addPackage('slideshowmanager',$slideshowmanagerPath.'model/');

$otherProps = array(
    'processors_path' => $slideshowmanagerPath . 'processors/'
);

$response = $modx->runProcessor('mgr/album/getlist', $properties, $otherProps);
$albums = $modx->fromJSON($response->response);

$output = '';
foreach($albums['results'] as $album) {
    if (!empty($output)) $output .= '||';
    $output .= $album['title'] .'=='.$album['id'];
}

return $output;
