Pulling Data from Parent Resource

Hello

I have minor issue thats taking me for a ride.
I use getResources to generate the slides of a slideshow.
The images are sub resources, but i want to pull the Introtext from the Parent Resource.

Somehow I can only get the ID of the parent ressource ( it returns the number (x), but i want the introtext from that resource (x)
The template chunk i am using looks like this:

<div class="slide">
  <img src="[[phpThumbOf? &input=`assets/images/[[+document-image]]` &options=`&w=640`]]"alt="[[+pagetitle]]"/>
  <p class="description">[[+parent[[+introtext]]]]</p>
  <a href="[[++filemanager_path]][[+document-image]]">Original Image</a>
</div>

It´s probably straight forward, but i thought i would post it, because the template chunk might inspire someone

You can’t use it like that - [[+parent[[+introtext]] - the only thing that’s available in any resource is the [[+parent]] placeholder which holds the ID like you said.

You can simply use a snippet to fetch the rest of the parent though. Have a look at getResourceField.

You could do it with a custom snippet -- something like this:

[[!ParentIntrotext? &pid=`[[+parent]]`]]

<?php
/* ParentIntrotext snippet */
$parent = $modx->getObject('modResource', $scriptProperties['pid']);
if ($parent) {  /* make sure there *is* a parent */
    return $parent->get('introtext');
}

Thanks
One problem - multiple solutions - that´s MODX in a nutshell tongue

@Mark
I was just trying not to use getResourceField since it is beta, and i wanted to avoid to many snippet calls within snippet calls. Also i just upgraded to 2.1 and now the download of getResourceField via Package Management doesn´t work anymore. Guess it is one of those Add-Ons that need a rewirte for 2.1

@Bob
Tried your code. Created a snippet with the name: ParentIntrotext, but it didn´t work. I think i found 2 minor typos. A missing backtick here:

[[!ParentIntrotext? $pid=`[[+parent]] ]]`]]

And the snippet call wasn´t properly closed:

<?php
/* ParentIntrotext snippet */
$parent = $modx->getObject('modResource', $scriptProperties['pid']);
if ($parent) {  /* make sure there *is* a parent */
    return $parent->get('introtext');
}

Am i missing anything else ?
Thanks and no worries, you all inspired me for a plan B.

Sorry I am new to this forum. I made a typo.

It should be:

[[!ParentIntrotext? $pid=`[[+parent]]`]]

Should be:

[[!ParentIntrotext? &pid=`[[+parent]]`]]

With an ’&’
