我已经设法在 woocommerce 注册表中添加了几个额外的字段。但是在 chechout 表单中，我添加的所有字段都不会自动填充。未出现在结帐中的字段是：“国家”和“州”。 正如您在此图像 (https://postimg.cc/vc57qkkF) 中看到的，国家和州字段出现了一个选择。但我需要显示我在注册时输入的国家和州。 这是我添加到functions.php的代码：
/**

add_action( 'woocommerce_register_form', 'misha_add_register_form_field' );
function misha_add_register_form_field(){
woocommerce_form_field(
'billing_first_name',
array(
'type' => 'text',
'required' => true, // just adds an "*"
'label' => 'First name'
),
( isset($_POST['billing_first_name']) ? $_POST['billing_first_name'] : '' )
);
woocommerce_form_field(
'billing_last_name',
array(
'type' => 'text',

我还不能添加评论，所以我在这里添加了一个问题，并尽我最大的努力同时回答......如果需要，我会编辑。
首先， 只是为了调试目的以确保我走在正确的轨道上，我猜这些字段也不会自动填充在“我的帐户”页面上，对吗？
我看到您正在为国家和州创建文本字段。您需要使用内置的 WooCommerce 的 Country 和 State 字段类型，以便将存储的值映射到选择选项，从而自动选择正确的选项。
试试这个：
misha_add_register_form_field 函数顶部，以从 WC 获取国家/地区列表。$countries_obj = new WC_Countries();
$countries = $countries_obj->__get('countries');
misha_add_register_form_field() 函数中的 country 和 state 字段替换为以下内容：woocommerce_form_field(
'billing_country',
array(
'type' => 'country',
'label' => 'Country',
'required' => 1,
'class' => ['address-field']
),
''
);
woocommerce_form_field(
'billing_state',
array(
'type' => 'state',
'label' => 'State',
'required' => 1,
'class' => ['address-field'],
'validate' => ['state']
),
''
);
您需要更新这 2 个字段的验证和清理程序，并且可能需要做一些额外的工作以确保正确更新。 您可以参考 Using the WooCommerce API to get the country/state lists 和 Add Billing Address to Woocommerce Registration Page，因为它们似乎解决了相同的挑战。
