在Woocommerce结帐中，我正在尝试使特定运输国家/地区不需要电话字段。根据“ Make checkout phone field optional for specific countries in WooCommerce” 答案代码（效果很好），我尝试进行一些更改，以使该代码适用于发货国家/地区而不是 >计费国家/地区。
经过大量尝试，我无法弄清楚如何使其工作。
任何帮助都将是很棒的，并且将不胜感激。

以下代码将仅在特定的“发货” 国家/地区要求计费电话字段。
从Woocommerce 3.4+版本开始，Woocommerce表单字段发生了一些变化，因此在需要的地方提供了附加功能和代码。
我还扩展了代码以处理“我的帐户”>“编辑地址”中的电话字段行为，客户可以在其中更改其帐户数据。
这是完整的代码（在第一个功能中定义您的国家代码）：
// SETTINGS: The countries codes (2 capital letters) in the array
function defined_countries_for_phone_field(){
return array( 'UK', 'BE', 'GE', 'IT', 'ES' );
}
// Remove "(optional)" from non required "Billing phone" field
add_filter( 'woocommerce_form_field' , 'remove_checkout_optional_fields_label', 10, 4 );
function remove_checkout_optional_fields_label( $field, $key, $args, $value ) {
// Get the defined countries codes
$countries = defined_countries_for_phone_field();
// Get Customer shipping country
$shipping_country = WC()->customer->get_shipping_country();
// Only on checkout page and My account > Edit address for billing phone field
if( 'billing_phone' === $key && ( ( is_wc_endpoint_url( 'edit-address' )
&& ! in_array($shipping_country, $countries) ) || is_checkout() ) ) {
$optional = ' <span class="optional">(' . esc_html__( 'optional', 'woocommerce' ) . ')</span>';
$field = str_replace( $optional, '', $field );
}
return $field;
}
// Make the billing phone field optional (by default)
add_filter( 'woocommerce_billing_fields', 'filter_billing_phone_field', 10, 1 );
function filter_billing_phone_field( $fields ) {
// Get the defined countries codes
$countries = defined_countries_for_phone_field();
// Get Customer shipping country
$shipping_country = WC()->customer->get_shipping_country();
// Only on checkout page and My account > Edit address
if ( ( is_wc_endpoint_url( 'edit-address' )
&& ! in_array($shipping_country, $countries) ) || is_checkout() )
$fields['billing_phone']['required'] = false;
return $fields;
}
// Real time shipping country selection actions
add_action( 'woocommerce_after_order_notes', 'custom_checkout_scripts_and_fields', 10, 1 );
function custom_checkout_scripts_and_fields( $checkout ) {
$required = esc_attr__( 'required', 'woocommerce' );
// Get the defined countries codes
$countries = defined_countries_for_phone_field();
// Hidden field for the phone number validation
echo '<input type="hidden" name="billing_phone_check" id="billing_phone_check" value="0">';
$countries_str = "'".implode( "', '", $countries )."'"; // Formatting countries for jQuery
?>
<script type="text/javascript">
(function($){
var required = '<abbr class="required" title="<?php echo $required; ?>">*</abbr>',
countries = [<?php echo $countries_str; ?>],
location = $('#shipping_country option:selected').val(),
phoneCheck = 'input#billing_phone_check',
phoneField = '#billing_phone_field';
function actionRequire( actionToDo='yes', selector='' ){
if ( actionToDo == 'yes' ) {
$(selector).addClass("validate-required");
$(selector+' label').append(required);
} else {
$(selector).removeClass("validate-required");
$(selector+' label > .required').remove();
}
$(selector).removeClass("woocommerce-validated");
$(selector).removeClass("woocommerce-invalid woocommerce-invalid-required-field");
}
// Default value Once DOM is loaded (with a 300 ms delay)
setTimeout( function(){
actionRequire( 'no', phoneField );
if( $.inArray( location, countries ) >= 0 && $(phoneCheck).val() == '0' ){
actionRequire( 'yes',phoneField );
$(phoneCheck).val('1');
}
}, 300 );
// Live value
$( 'form.checkout' ).on( 'change', '#shipping_country', function(){
var location = $('#shipping_country option:selected').val();
if ( $.inArray( location, countries ) >= 0 && $(phoneCheck).val() == 0 ) {
actionRequire( 'yes' ,phoneField );
$(phoneCheck).val('1');
} else if ( $(phoneCheck).val() == 1 ) {
actionRequire( 'no' ,phoneField );
$(phoneCheck).val('0');
}
});
})(jQuery);
</script>
<?php
}
// Phone number validation, when the field is required
add_action('woocommerce_checkout_process', 'billing_phone_field_process');
function billing_phone_field_process() {
// Check if set, if its not set add an error.
if ( ! $_POST['billing_phone'] && $_POST['billing_phone_check'] == '1' )
wc_add_notice( __( 'Please enter a number phone.' ), 'error' );
}
代码进入您的活动子主题（或活动主题）的function.php文件中。在WooCommerce 3.4及更高版本中进行了测试并可以工作。

非常感谢@LoicTheAztec提供的原始答案，但是该解决方案现在给出了不稳定的结果，并且只是在必需状态和可选状态（打开/关闭）之间交替切换电话字段。
原始答案也未考虑仅使用帐单地址且未输入单独的收货或送货地址的客户。
