[Resolved] Filtering by taxonomy when taxonomy is hierarchical

In a nested View, with a post inner and taxonomy outer, set the inner View’s Query Filter to “Set by the parent Taxonomy View.”

If the taxonomy is hierarchical, the filter passes not just the items matching a taxonomical category, but those matching the category’s children as well.

So a post can get shown multiple times, once for its category, once for the category’s parent, once for the category’s grandparent, etc.

This seems like a bug to me, but either way, is there a way to filter only posts that match the categorical term, not those that match the term’s children also?

Dear John,

There isn't such a built-in feature within Views plugin, but you can try with the Views filter hook "wpv_filter_tax_filter_include_children", for example, add below codes into your theme/functions.php:

add_filter('wpv_filter_tax_filter_include_children', 'no_child_term_func', 10, 3);
function no_child_term_func($include_child, $category_name, $view_id){
	if($view_id == 123 && $category_name == 'my-tax-slug'){
		$include_child = false;
	}
	return $include_child;
}

Please replace 123 with the child view's ID, replace "my-tax-slug" with the custom taxonomy slug.

That worked. Thanks!

It would be nice if this were a standard option.
