php - woocommerce 中有条件地未设置结帐字段

Question

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:

这是代码:

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' );
