Question

我正在使用WooCommerce API获取国家/地区列表。我正在做：

Employee Name: James Murray

但是，如何获取默认选定国家/地区的州名单？此外，当用户更改国家/地区时，Woo是否内置了可以应用于国家/地区字段以更新状态框的内容，或者我是否必须自己构建该功能？

另外，我知道我可以通过以下方式获取一个国家的州：

@Employee_ID    varchar(8) = NULL

SELECT s.Employee_ID, p.FIRST_NAME, p.LAST_NAME
    FROM [dbo].[Employee] e INNER JOIN [dbo].[Person] p ON e.PERSON_ID = p.PERSON_ID
    WHERE p.Employee_ID = @Employee_ID

...但我不确定如何让默认的选定国家传入其中？

我也知道他们有一个合并的国家/州名单，你可以加载，但这对于可用性来说非常麻烦和太长。

Answer 1

试试这个，你仍然需要一些javascript来使它工作。我不知道默认情况下是否有任何方法使状态下拉列表按照国家/地区下拉列表工作。我认为它是有帮助的，尝试一下，让我知道，如果它有效。

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 );

所以这会让您的国家/地区下拉

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才能让它按照您的意愿运行。您可以考虑通过woocommerce_form_field。

我在我的functions.php上添加了以下代码，屏幕截图显示了我的内容。需要了解您的结帐页面以使其更好。 < / p>

＆＃34;我相信这就是创建与默认结帐页面相同的HTML元素。＆＃34;

//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（对于国家选择的美国（美国））： -

Answer 2

这被称为＆＃34;基地国家＆＃34;通过WooCommerce：

$woo_countries = new WC_Countries();

// Get default country
$default_country = $woo_countries->get_base_country();

// Get states in default country
$states = $woo_countries->get_states( $default_country );

了解更多in the API docs。

应注意default WooCommerce billing form template logic确保预先选择默认国家/地区。这是它的样子：

<?php foreach ( $checkout->checkout_fields['billing'] as $key => $field ) : ?>

    <?php woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); ?>

<?php endforeach; ?>

传递给woocommerce_form_field()的第三个参数可确保预先填充默认国家/地区。

使用WooCommerce API获取国家/州名单
