  • Hi @mikiamomik

    I’m afraid this is hard to achieve. I think you can use the acf/fields/taxonomy/query hook to mark if a query is requested by ACF like this:

    function my_taxonomy_query( $args, $field, $post_id ) {
        // add custom args to be checked by get_terms hook
        $args['test'] = 'testing';
        // return
        return $args;
    add_filter('acf/fields/taxonomy/query', 'my_taxonomy_query', 10, 3);

    After that, you can modify the returned terms using the “get_terms” hook like this:

    function example_callback_taxonomy( $terms, $taxonomies, $args ) {
        if(isset($args['test'])){ //check if it called from acf/fields/taxonomy/query
            remove_action('get_terms', 'example_callback_taxonomy', 20);
            // modify the args if you want
            $args['order'] = 'ASC';
            //get it from other blog
            $terms = get_terms( 'category', $args );
            add_filter('get_terms', 'example_callback_taxonomy', 20, 3);
            return $terms;
    add_filter( 'get_terms', 'example_callback_taxonomy', 20, 3 );

    The value wasn’t showing up because ACF is checking if your current blog has the taxonomy or not. You need to modify the select 2 field using jQuery and the acf/input/admin_footer.

    I hope this makes sense.
