我已经按照下面的代码使用该方法使checkout字段可选 . 但是，我发现当非登录用户提交订单时，填写地址字段的警报会跳出 .
add_filter( 'woocommerce_default_address_fields' , 'custom_override_default_address_fields' );
function custom_override_default_address_fields($address_fields) {
$address_fields['first_name']['required'] = false;
$address_fields['last_name']['required'] = false;
$address_fields['address_1']['required'] = false;
$address_fields['address_1']['placeholder'] = '';
$address_fields['address_2']['required'] = false;
$address_fields['address_2']['placeholder'] = '';
$address_fields['postcode']['required'] = false;
$address_fields['city']['required'] = false;
return $address_fields;
}
顺便说一下，我还尝试将结算和发货字段单独选为链接WooCommerce: Disabling checkout fields with a filter hook中的方法 .
