Hi @hiroshi
I’m afraid this is not possible because ACF will try to get the parents if the taxonomy is hierarchical so that it can show the terms in a tree layout. To fix it, you need to modify the core file. In “wp-content/plugins/advanced-custom-fields-pro/fields/taxonomy.php”, please search this line of code:
// this will fail if a search has taken place because parents wont exist
if( empty($args['search']) ) {
Kindly change it to this one:
// this will fail if a search has taken place because parents wont exist
if( empty($args['search']) && $parent ) {
After that, you can use this code to show only the child:
function myfunction( $args, $field, $post_id ) {
$parents_args = array(
'hide_empty' => 0,
'parent' => 0,
'fields' => 'ids',
);
$parent_ids = get_terms( 'custom-taxonomy', $parents_args );
$args['exclude'] = $parent_ids;
return $args;
}
add_filter('acf/fields/taxonomy/query/name=taxonomy', 'myfunction', 10, 3);
Also, could you please open a new ticket so this issue can be passed directly to the plugin author? You can open a new ticket here: https://support.advancedcustomfields.com/new-ticket.
Thanks 🙂
