Within Flexible content, I have a taxonomy field type, but this returns ALL categories, which is fine if you only have a few categories of the same type.
But when you have lots of categories that are grouped, showing all the categories is unnecessary and confusing.
So, in my case, I have several categories under “membership levels”, but also other categories for news. In the flexible content field, I want the user to select from a list that only includes the membership levels – having all the “news” categories listed makes no sense.
Is there a way to natively filter this field so it shows a list of taxonomies that includes ONLY the children of a parent category?
Thank you
You can limit the terms shown using one of these two filters
if you are using a select field – acf/fields/taxonomy/query
If you are using a radio or checkbox field – acf/fields/taxonomy/wp_list_categories
John, thanks for the response. I read through the link you provided and worked it out! In my case, I was able to add the following code, and because I linked it to the key of the field, it only affected that one set of radio buttons. Perfect! Here’s my code:
add_filter(‘acf/fields/taxonomy/wp_list_categories/key=field_69ee9943be86f’, ‘my_acf_fields_taxonomy_query’, 10, 2);
function my_acf_fields_taxonomy_query( $args, $field ) {
// Order by most used.
$args[‘child_of’] = ’14’;
$args[‘orderby’] = ‘title’;
$args[‘order’] = ‘ASC’;
return $args;
}
Sorry for getting back to you late. Glad that you worked it out.
John – is there any way to INCLUDE the parent category in the list?
You would need to build an array of term IDs to use in the “include” argument
$children = get_term_children($term_id, 'TAXONOMY');
$include = array_merge(array($term_id), $children);
$args['include'] = $include;
