我正在使用 WooCommerce API 获取国家列表。我正在做:

$woo_countries = new WC_Countries();
$countries = $woo_countries->get_allowed_countries();

但是，如何获得默认选定国家/地区的州列表？此外，当用户更改国家/地区时，Woo 是否内置了一些我可以应用到国家/地区字段以更新状态框的东西，还是我必须自己构建该功能？

此外，我知道我可以通过以下方式获取一个国家/地区的州:

$woo_countries->get_states(country_code);

...但我不确定如何将默认选择的国家/地区传递给它？

我也知道他们有一个组合的国家/州列表，你可以加载，但这真的很乱，而且太长了，不实用。

最佳答案

试试这个，你仍然需要一些javascript来让它工作。我不知道默认情况下是否有任何方法可以让状态下拉列表按照国家下拉列表工作。我认为它很有帮助，请尝试一下，如果有效，请告诉我。

global $woocommerce;
$countries_obj   = new WC_Countries();
$countries   = $countries_obj->__get('countries');
$default_country = $countries_obj->get_base_country();
$default_county_states = $countries_obj->get_states( $default_country );

所以这会让你的国家下拉

global $woocommerce;
$countries_obj   = new WC_Countries();
$countries   = $countries_obj->__get('countries');
echo '<div id="my_custom_countries_field"><h2>' . __('Countries') . '</h2>';

woocommerce_form_field('my_country_field', array(
'type'       => 'select',
'class'      => array( 'chzn-drop' ),
'label'      => __('Select a country'),
'placeholder'    => __('Enter something'),
'options'    => $countries
)
);
echo '</div>';

和州下拉列表

    global $woocommerce;
    $countries_obj   = new WC_Countries();
    $countries   = $countries_obj->__get('countries');
    $default_country = $countries_obj->get_base_country();
    $default_county_states = $countries_obj->get_states( $default_country );

    echo '<div id="my_custom_state_field"><h2>' . __('States') . '</h2>';

    woocommerce_form_field('my_state_field', array(
    'type'       => 'select',
    'class'      => array( 'chzn-drop' ),
    'label'      => __('Select a state'),
    'placeholder'    => __('Enter something'),
    'options'    => $default_county_states
    )
    );
    echo '</div>';

您需要一些 javascript 才能使其按您的意愿运行。您可以考虑通过 woocommerce_form_field .

我在我的 functions.php 中添加了以下代码，屏幕截图显示了我得到的内容。需要了解您的结帐页面以使其变得更好。

“我相信这一切都是为了创建与默认结帐页面中相同的 HTML 元素。”

//Reordering woocommerce billing form on checkout page
add_filter( 'woocommerce_checkout_fields','reorder_woo_billing_fields' );
function reorder_woo_billing_fields( $fields ) {
    //$fields2['billing']['billing_email'] = $fields['billing']['billing_email'];
    $fields2['billing']['billing_first_name'] = $fields['billing']['billing_first_name'];
    $fields2['billing']['billing_last_name'] = $fields['billing']['billing_last_name'];
    $fields2['billing']['billing_company'] = $fields['billing']['billing_company'];
    $fields2['billing']['billing_address_1'] = $fields['billing']['billing_address_1'];
    $fields2['billing']['billing_address_2'] = $fields['billing']['billing_address_2'];
    $fields2['billing']['billing_city'] = $fields['billing']['billing_city'];
    $fields2['billing']['billing_country'] = $fields['billing']['billing_country'];
    $fields2['billing']['billing_state'] = $fields['billing']['billing_state'];
    $fields2['billing']['billing_postcode'] = $fields['billing']['billing_postcode'];
    $fields2['billing']['billing_phone'] = $fields['billing']['billing_phone'];

    $fields2['billing']['billing_country']['class'] = array('box', 'form-row form-row-first address-field update_totals_on_change validate-required woocommerce-validated');
    $fields2['billing']['billing_state']['class'] = array('box', 'form-row form-row-last address-field validate-required validate-state woocommerce-invalid woocommerce-invalid-required-field');
    $fields2['billing']['billing_postcode']['class'] = array('box', 'form-row form-row-first address-field validate-required validate-postcode');
    $fields2['billing']['billing_phone']['class'] = array('box', 'form-row form-row-last validate-required validate-phone');
    //$fields2['billing']['billing_email']['class'] = array('box', 'form-row form-row-wide validate-required validate-email');
    $fields2['billing']['billing_postcode']['clear'] = '';
    $fields2['shipping'] = $fields['shipping'];
    $fields2['account'] = $fields['account'];
    $fields2['order'] = $fields['order'];

     return $fields2;
}


add_action( 'woocommerce_checkout_init', 'woocommerce_countries_states', 10, 1 );
function woocommerce_countries_states( $checkout ) {
    global $woocommerce;
    $countries_obj   = new WC_Countries();
    $countries   = $countries_obj->__get('countries');
    $default_country = $countries_obj->get_base_country();
    $default_county_states = $countries_obj->get_states( $default_country );


    $checkout->checkout_fields['account']['billing_country'] = array(
        'type'              => 'select',
        'label'             => __( 'Default Contries', 'woocommerce' ),
        'required'          => true,
        'options'    => $countries
    );

    $checkout->checkout_fields['account']['billing_country'] = array(
        'type'              => 'select',
        'label'             => __( 'Default Contries', 'woocommerce' ),
        'required'          => true,
         'options'    => $default_county_states
    );
}

我得到的 HTML 有点像(对于选择的国家 United States(US)):-
