Filters the query $args used by WP_Term_Query to display terms in the Taxonomy field when displayed as a Select or Multiselect dropdown.


  • Added in version 5.0.0


apply_filters( 'acf/fields/taxonomy/query', $args, $field, $post_id );
  • $args (array) The query args. See WP_Term_Query for available args.
  • $field (array) The field array containing all settings.
  • $post_id (int|string) The current post ID being edited.


This filter provides modifiers to target specific fields. The following filter names are available:

  • acf/fields/taxonomy/query Applies to all fields.
  • acf/fields/taxonomy/query/name={$name} Applies to all fields of a specific name.
  • acf/fields/taxonomy/query/key={$key} Applies to all fields of a specific key.


This example demonstrates how to modify some of the Taxonomy field query args.


add_filter('acf/fields/taxonomy/query', 'my_acf_fields_taxonomy_query', 10, 3);
function my_acf_fields_taxonomy_query( $args, $field, $post_id ) {

    // Show 40 terms per AJAX call.
    $args['number'] = 40;

    // Order by most used.
    $args['orderby'] = 'count';
    $args['order'] = 'DESC';

    return $args;
