我之前使用的是 this answer根据选择的送货方式隐藏结帐字段，在更新(3.4.2 当前版本)之前它工作正常我认为不确定发生了什么变化但它不再按预期工作。

Previously when local pickup was chosen some fields were hidden and made optional and when delivery was chosen it would show those fields again all via dynamically without reloading the page.

Now it shows and hides the fields as required however, when delivery is chosen it is showing the correct fields marked as mandatory but also has the (optional) sign next to it and it makes it optional. 见下图。

下面是我修改后的截图:

add_filter('woocommerce_default_address_fields', 'custom_default_checkout_fields', 10, 1 );
function custom_default_checkout_fields( $address_fields ) {
$custom_fields = array( 'country', 'address_1', 'address_2', 'state', 'postcode');
foreach($custom_fields as $field)
    $address_fields[$field]['required'] = false;
return $address_fields;
}

add_action( 'wp_footer', 'custom_checkout_field_script' );
function custom_checkout_field_script() {

$pickpoint = 'local_pickup:2';
$free_delivery = 'free_shipping:1';
$flat_rate = 'flat_rate:3';

$required = esc_attr__( 'required', 'woocommerce' );
?>
<script>
    jQuery(function($){

        var shippingMethod = $('input[name^="shipping_method"]:checked'),
            required = '<abbr class="required" title="<?php echo $required; ?>">*</abbr>',
            shippingChecked = $('input#ship-to-different-address-checkbox');

        shippingChecked.change( function(){
            console.log('Shipping Checked: '+shippingChecked.prop('checked'));
        });

        function showHide( actionToDo='show', selector='' ){
            if( actionToDo == 'show' )
                $(selector).show(function(){
                    $(this).addClass("validate-required");
                    $(this).removeClass("woocommerce-validated");
                    $(this).removeClass("woocommerce-invalid woocommerce-invalid-required-field");
                    if( $(selector+' > label > abbr').html() == undefined )
                        $(selector+' label').append(required);
                });
            else
                $(selector).hide(function(){
                    $(this).removeClass("validate-required");
                    $(this).removeClass("woocommerce-validated");
                    $(this).removeClass("woocommerce-invalid woocommerce-invalid-required-field");
                    if( $(selector+' > label > abbr').html() != undefined )
                        $(selector+' label > .required').remove();
                });
        }

        if( shippingMethod.val() == '<?php echo $pickpoint; ?>' )

            showHide('hide','#billing_address_1_field' );

更新 2

要从 Woocommerce 版本 3.4 引入的结帐字段标签中删除 “(可选)” 文本，就像以前一样，您需要添加以下代码:

// PHP: Remove "(optional)" from our non required fields
add_filter( 'woocommerce_form_field' , 'remove_checkout_optional_fields_label', 10, 4 );
function remove_checkout_optional_fields_label( $field, $key, $args, $value ) {
    // Only on checkout page
    if( is_checkout() && ! is_wc_endpoint_url() ) {
        $optional = '&nbsp;<span class="optional">(' . esc_html__( 'optional', 'woocommerce' ) . ')</span>';
        $field = str_replace( $optional, '', $field );
    }
    return $field;
}

// JQuery: Needed for checkout fields to Remove "(optional)" from our non required fields
add_filter( 'wp_footer' , 'remove_checkout_optional_fields_label_script' );
function remove_checkout_optional_fields_label_script() {
    // Only on checkout page
    if( ! ( is_checkout() && ! is_wc_endpoint_url() ) ) return;

    $optional = '&nbsp;<span class="optional">(' . esc_html__( 'optional', 'woocommerce' ) . ')</span>';
    ?>
    <script>
    jQuery(function($){
        // On "update" checkout form event
        $(document.body).on('update_checkout', function(){
            $('#billing_country_field label > .optional').remove();
            $('#billing_address_1_field label > .optional').remove();
            $('#billing_postcode_field label > .optional').remove();
            $('#billing_state_field label > .optional').remove();
            $('#shipping_country_field label > .optional').remove();
            $('#shipping_address_1_field label > .optional').remove();
            $('#shipping_postcode_field label > .optional').remove();
            $('#shipping_state_field label > .optional').remove();
        });
    });
    </script>
    <?php
}

代码进入事件子主题(或事件主题)的 function.php 文件。在 Woocommerce 版本 3.4+ 中测试并工作。

You could merge the included jQuery code with your existing jQuery code…
