Can't Query a Term from a Custom Taxonomy

[developdaly]

Using the following query I should be able to return a subset of posts with a post type of "listing" in a custom taxonomy of "listing-neighborhood" and term/tag ID of "12".

/?taxonomy=listing-neighborhood&post_type=listing&tag_ID=12

/?taxonomy=listing-neighborhood&post_type=listing works, but I'm not able to specify a term.

I was told this may be due to post_tag still being hardcoded into query.php around line 1940 instead of a term variable.

Try

/?taxonomy=listing-neighborhood&post_type=listing&term=term-slug

When using custom taxonomies you are using terms not tags. It would be confusing if tag_id were able to query any term taxonomy.

marking as invalid

So is there not a method of retrieving terms by their ID?

The backend makes use of /wp-admin/edit-tags.php?action=edit&taxonomy=listing-neighborhood&post_type=listing&tag_ID=12.

Is there a term_ID maybe?

I just looked a bit in WP_Query and it looks like there are no input point to use it querying for a nunerical term_id.

get_category() might be helpfull in that case to convert the numerical id into a category object first and obtain the name.
