如何有条件地从服务器端取消设置其他两个字段并从中删除所需的验证？

表单如下所示：

代码如下：

function bs_filter_checkout_fields($fields){
    $fields['billing'] = array(

        'add_type' => array(
            'type' => 'radio',
            'label' => __( 'Address Type' ),
            'options' => array( 'house' => __( 'House' ), 'building' => __( 'Building' ), 'office' => __( 'Office' ) ),
            'required' => true
                ),
        'add_house_name' => array(
            'type' => 'text',
            'required'      => true,
            'placeholder' => __( 'House Name/Number' ),
            'label' => __( 'House Name/Number' )
        ),
        'add_building_name' => array(
            'type' => 'text',
            'required'  => true,
            'placeholder' => __( 'Building Name/Number' ),
            'label' => __( 'Building Name/Number' )
        ),
        'add_office_name' => array(
            'type' => 'text',
            'required'  => true,
            'placeholder' => __( 'Office Name/Number' ),
            'label' => __( 'Office Name/Number' )
        ),
    );
return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'bs_filter_checkout_fields' );
function bs_conditional_scripts() {
    wc_enqueue_js( "
        $( '#add_type_house' ).change( function () {

            if ( $( this ).is( ':checked' ) ) {
                $('#add_building_name_field').hide();
                $('#add_office_name_field').hide();
                $( '#add_house_name_field' ).show();
            }

        } ).change();

    $( '#add_type_building' ).change( function () {

        if ( $( this ).is( ':checked' ) ) {
            $( '#add_house_name_field' ).hide();
            $('#add_office_name_field').hide();
            $('#add_building_name_field').show();
        }

    } ).change();


    $( '#add_type_office' ).change( function () {

        if ( $( this ).is( ':checked' ) ) {
            $( '#add_house_name_field' ).hide();
            $('#add_building_name_field').hide();
            $('#add_office_name_field').show();
        }

    } ).change();
    " );
}

add_action( 'wp_enqueue_scripts', 'bs_conditional_scripts' );
