I need the list of category names, but only the categories that have been tagged in entries that are related (a Playa relationship) to another entry (I know, it's getting down to snow-fortress Inception levels).
Here's my Low Variable (an early-parsed textarea variable), called "lv_region_entry_ids":
{exp:channel:entries url_title="{segment_3}"}{exp:playa:parent_ids}{/exp:channel:entries}
And here's the place I'm trying to use it:
{exp:gwcode_categories entry_id="{lv_region_entry_ids}"} (some code) {/exp:gwcode_categories}
That doesn't work, and I've read in a few places that when dealing with LV and Playa you have to use the pair tag instead of the the global variable syntax. But that's where I'm drawing a blank on how to do that.
{lv_region_entry_ids}
in a template by itself? Is it actually being parsed?
