[Closed] Filter a view by child post taxonomy

[heatherS]

I am trying to:
Filter a view by a child post taxonomy

I visited this URL: hidden link

I expected to see:
The posts filtered by the child State and Discipline taxonomies on the child post type Approvals.

Instead, I got:
The posts are not displaying based on Approval State and Discipline taxonomies

In this case the view is displaying Products. Each product has several Approval child posts. Both the Products and the Approval post types use the taxonomies State and Discipline (but for 2 different purposes)

In this view I want the State and Discipline select fields to look into the Approval Child Post, not the Product itself

This is how I have setup the view's search (the slug of Approvals is "hceu-approval")

Hi Heather,

Thank you for contacting our support forum.

From your post I gather you have a Parent/Child relationship on your site.

Then you are trying to filter the Parent posts by the taxonomies of the Child posts using views correct?

Does the Parent CPT have the same taxonomies as the children ?

If not then you are not able to filter the parent view by the child post taxonomies.

Please let me know.

Thanks,
Shane

They have the same taxonomies, but different values for those taxonomies.

Hi Heather,

It wouldn't be possible either since the view can only sort based on the taxonomy terms that are attached to the current custom post type.

So a workaround to this could be that you allow the parent to have the same taxonomy terms as the child.

What is it that you are trying to achieve exactly, maybe I could brainstorm some ideas.

Thanks,
Shane

If we made those fields instead of taxonomies at the child level, could we filter by that?

Hi Heather,

I would need to know what you want to achieve first. Because this would pose the same issue as the taxonomy because the parents wouldn't have the same custom field values or not have the custom fields attached to it.

Look at it like this, if you are displaying the parent posts then you can only filter for attributes of the Parent and not for the child.

Even thought the posts are related in Types, technically they are still separate Post Types.

Please let me know if this helps.
Thanks,
Shane
