I don’t get the documentation for acf/update_field() either. It says the $field parameter is the field array containing all settings. All the settings of what? The field I want to collect data from? In that case it seems this should work but it doesn’t.

function save_updated_acf_fields($location)
{
    // Collect GM field data
    $location = get_field('field_634147f894e08', $post_id);
    $gmap_street_name = $location['street_name'];
    $gmap_street_nbr = $location['street_number'];

    // Fields retrieving updated values
    $empty_street_name = get_field('field_6341483d94e09', $post_id);
    $empty_street_nbr = get_field('field_634151528a090', $post_id);

    if ($location) {
        $empty_street_name = $gmap_street_name;
        $empty_street_nbr = $gmap_street_nbr;
    }
}

add_filter('acf/update_field ', 'save_updated_acf_fields', 10, 1);

Would you please translate the documentation into something a plain dummy like myself can understand?
