Thanks for reporting with such detail. I’ll look into this tomorrow and follow up.

If this helps for more context, I moved the taxonomy out of the Repeater field, like to make it be just a standalone Taxonomy type field in ACF, and got the same results.

After this last attempt that makes me think (in case this is a bug) that this is not related with having the Taxonomy type field nested inside a Repeater ACF field. It looks like wp-graphql/wp-graphql-acf currently is not capable to query the Taxonomy terms from ACF.

Because for the record, querying this Taxonomy the regular way it does returns the terms values as expected.

@elvismdev I'm looking into this now.

Thanks @jasonbahl !

@jasonbahl I have the same Issue with Taxomony-Fields inside a Flexible Content layout

Okay so the problem I had with taxonomies was actually a different one. I didn't get all the pages with all the childPages and therefore the childPage with the taxonomy field wasn't available.

I believe this issue comes from how WPGraphQL Core loaded terms in hierarchical taxonomies.

For a while, WPGraphQL Core's loader would load only top level terms with parent=>0, and you had to explicitly ask for children.

In the case of this ACF field, the underlying query ended up being something like:

$query = new WP_Term_Query( [
  'include' => [ 1, 2, 3 ]
  'parent' => 0
] );

And let's say terms 2 and 3 were child/grandchild.

This query would return just term 1, because it's the only one with parent => 0.

This was fixed in WPGraphQL core and from my testing this seems to be working in WPGraphQL for ACF now.

Current

Current behavior with:

• WPGraphQL v1.3.8
• WPGraphQL for ACF v0.5.2
• ACF Pro v5.9.4

I can set the value of a taxonomy field in a repeater with a top-level term and a grandchild term and get these terms in the response:

Upcoming v0.6.0

In the upcoming v0.6.0 release, the shape of the query changes a bit to respect the post->terms connection better, but the functionality of returning related terms whether they are top-level or children, remains.
