How can I get direct children of a specific resource?

I would like to get the title, content etc of direct children to a specific resource to neatly line them in <ul>'s and <li>'s. How can I achieve this?

https://forums.modx.com/thread/31993/getchildren-simple-example-of-xpdo

The example on this page does almost exactly what I want, except that it is for the children of the current page. But I would like to get children from a specific resource.

Any help to this or something similar would be great.

Thanks!

getResources or wayfinder, both can do that.

If you need to create a navigation or something like that, you would prefer to use wayfinder.

For other listings, getResources.

I've tried them but I can't figure out how to do it!

<ul>
[[getResources? &parents=`[[*id]]` &tpl=`yourTplchunk`]]
</ul>

Or, if you prefer a custom-snippet, something like that should do it.

Modified version of Marks one:

<?php

$tpl = $modx->getOption('tpl', $scriptProperties, false);
$parent = $modx->getOption('parent', $scriptProperties, $modx->resource->get('id'));
$o = $modx->getOption('default', $scriptProperties, '');

// Check if there is a tpl set, if not return an error
if (!$tpl) {
    return 'No template given.';
}

// First fetch all the children of any resource
$classname = 'modResource';
$c = $modx->newQuery($classname);
$c->where(array('parent' => $parent));

if ($children = $modx->getCollection($classname, $c)) {
    // Start the output
    $o = '<h2>[[*pagetitle]]</h2><ul>'; // Look through the results...
    foreach ($children as $child) {
        // ... fetching the needed info...
        $out = array(
            'id' => $child->get('id'),
            'pagetitle' => $child->get('pagetitle'),
            'menutitle' => $child->get('menutitle'),
            'longtitle' => $child->get('longtitle')); // ... and adding it to the output as placeholders in the chunk
        $o .= $modx->getChunk($tpl, $out);
    }
    // Don't forget to close the list
    $o .= '</ul>';
}

// Return the output
return $o;

Thanks, that looks like what I want!

How can I call it? I have placed it in a snippet called "getEvents" and I have a chunk called "getChildrenTpl" like the one in the other example.

Would this be correct if the parent resource have id 16:

[[getEvents? &id='16' &tpl='getChildrenTpl']]

When I do this it just empty. Same if I use:

<ul>
[[getResources? &parents=`[[*id]]` &tpl=`yourTplchunk`]]
</ul>

Do I need to do something specific to the resource to make it show? Now its published but hidden from the menu.

try:

[[getEvents? &parent=`16` &tpl=`getChildrenTpl`]]

or:

<ul>
[[getResources? &parents=`[[*id]]` &tpl=`yourTplchunk` &showHidden=`1`]]
</ul>

[[getEvents? &parent=`16` &tpl=`getChildrenTpl`]]

is still empty.

<ul>
[[getResources? &parents=`[[*id]]` &tpl=`yourTplchunk` &showHidden=`1`]]
</ul>

prints the full array of each resource from the resource named Home, the first one with id 1 like:

Array
(
    [tpl] => 'getChildrenTpl'
    [tplOdd] => 
    [tplFirst] => 
    [tplLast] => 
    [sortby] => publishedon
    [sortbyTV] => 
    [sortbyTVType] => string
    [sortbyAlias] => 
    [sortbyEscaped] => 0
    [sortdir] => DESC
    [sortdirTV] => DESC
    [limit] => 5
    [offset] => 0
    [tvFilters] => 
    ...

Its four arrays, one for each child resource under home. But nothing from resource 16 which is on the same level as Home (1). Any ideas?

forgot:

$classname = 'modResource';

added it above.

if you want all the childs of 16 then:

<ul>
[[getResources? &parents=`16` &tpl=`yourTplchunk` &showHidden=`1` &limit=`0` &depth=`1`]]
</ul>

and you will need your own chunk for 'yourTplchunk'
