I’m trying to figure out a way to dynamically pull in posts based off of the posts attached taxonomy terms in a custom post type.

I have a custom post type ‘Products’ set up with a few associated custom taxonomies. The one I’m trying to target for this project is ‘Vendors’ (slug = product-vendor).

I need to figure out how to do this dynamically because there are 30 vendors and they wil be adding more every once in awhile, I don’t want to do and if statement for every single one… or I’ll have to update the theme everytime they add a new vendor.

There will only be 1 vendor attached to each product, so I thought this would be the best way to get it to pull the most recent 5 products.
