So I’ve changed it to:
/* sets the acf to product type text */
add_filter('acf/load_field/name=product_type', function($field) {
global $post;
$field['value'] = get_product( $post->ID )->get_type();
return $field;
});
… which works, but I get an error (There has been a critical error on this website) when attempting to edit the field group for the acf. What can I do to avoid that (other than temporarily removing the filter above)?
