The site referenced below is running on MODX 2.2.6-pl on a standard LAMP environment.
So here's what I'm attempting to do: I've got individual portfolio pages on my site. These portfolio pages are all child resources of a Container named "Portfolio". So in the MODX tree I have a basic setup like this:
-- Portfolio
--- ABC Widgets
--- XYZ Widgets
--- ACME products inc.
--- Cool Company Project
etc.
Each one of these child Resources of "Portfolio" has a T.V. named "Work Category". The "Work Category" is a T.V. with radio options pulling the names of child Resources from a container that I have in the tree named "Work Category". The "Work Category" is a container which child resources like "Web Design", "Print", "Packaging", "CMS", etc. When I setup a new Portfolio page to put in the "Portfolio" container, I choose from the radio options which category this Portfolio item is categorized.
So here's my challenge. When a visitor views anyone of the Portfolio pages above, I will have a link the user can click named "Next Project" so they can view the next portfolio item in the tree that has the same T.V. Category chosen for the "Work Category". My goal is that every time they click "Next Project", they basically are traversing the MODX tree to find the next resource tagged with the same T.V. They'll basically be cycling through the tree. Hope that makes sense.
Thanks!

I think you'd have to do something custom with a getCollection query... don't know if there's anything pre-packaged that will do this for you.

So let me see if I understand you correctly, you want to go from ACB Widgets Work Category to XYZ Widgets Work Category items?
I can't quite understand if you want to traverse from ABC Widgets to XYZ Widgets or from ABC Widgets Work Category Items to XYZ Widgets Work Category items.
I think you could probably make a navigation using getResources and filter which resources by the TV value of the category, again I'm not clear on what you want to achieve.

That's just tagging; this would be no different than having links to items with the same tag. I think there are some extras that deal with this.

Hey benmarte, thanks for asking me to clarify that...sorry if I didn't communicate that point well. I want to traverse the tree to go to the next Resource that has the same T.V. category tagged as the current Resource being viewed. So if a visitor is on a page that is tagged in MODX as "CMS", when they click the next page link, it will take them to the next Resource in the MODX tree that is tagged with "CMS" for that same T.V. You can see a live example on a site I recently viewed:
http://viget.com/work/hellowallet
If you notice on the left and right side of the page, there are arrows leading the site visitor to the either the next page that is in the db. Not sure how exactly they're deciding what is the next page (publication date or some other variable), but I'm trying to recreate that same UI functionality, but I just need to figure out how to traverse the MODX tree to find the previous and next Resource that is tagged with the same category.
Hope that helps.

I think you want something like this snippet (untested):
<?php
$tvId =12; /* ID of the WorkCategory TV */
/* get the category for this page */
$currentCategory = $modx->resource->getTVValue($tvId);
/* you probably want to make this a query with sortby */
$tvrs = $modx->getCollection('modTemplateVarResource', array('tmplvarid' => $tvId, 'value' => $currentCategory));
/* Now you have an array of modTemplateVarResource objects for Resources with the same category
(will include the current one). */
/* make a new array of Resource Ids to get consecutive indexes (0,1,2,... */
$linkList = array();
$output = "";
foreach($tvrs as $tvr) {
$linkList[] = $tvr->get('contentid')
}
/* grab the index of the current resource */
$current = array_search($modx->resource->get('id'), $linkList);
$maxIndex = count($linkList) - 1;
/* Previous link for all but first doc */
if ($current != 0) {
$url = $modx->makeUrl($linkList[$current - 1], "", "", "full");
$output .= '<a href="' . $url . '">Previous -</a>';
} else {
$output .= 'Previous -'; /* non link */
}
/* Next link for all but the last doc */
if ($current < $maxIndex) {
$url = $modx->makeUrl($linkList[$current + 1], "", "", "full");
$output .= '<a href="' . $url . '">- Next</a>';
} else {
$output .= '- Next'; /* non link */
}
return $output;

Hey BobRay,
Thanks so much...this is really good stuff. I'm gonna play around with this code right now. Thanks!
