根据 Woocommerce 中的访客位置后端错误隐藏价格

Question

在上一个问题中，我询问了如何向英国境外的访客隐藏价格。

根据一个答案，我成功地使用了这段代码

add_filter( 'woocommerce_get_price_html', 'country_geolocated_based_hide_price', 10, 2 );
function country_geolocated_based_hide_price( $price, $product ) {
    if( get_current_user_id() > 0 ) {
        $country = WC()->customer->get_billing_country();
    } else {
        // Get an instance of the WC_Geolocation object class
        $geo_instance  = new WC_Geolocation();
        // Get geolocated user geo data.
        $user_geodata = $geo_instance->geolocate_ip();
        // Get current user GeoIP Country
        $country = $user_geodata['country'];
    }
    return $country !== 'GB' ? '' : $price;
}

这按预期工作，但是当我尝试在管理区域编辑我的产品时，我在每个产品的价格栏中收到此错误：

Fatal error: Uncaught Error: Call to a member function get_billing_country() on null in /var/sites/o/oxfordriderwear.com/public_html/wp-content/themes/storefront/functions.php:61 Stack trace: #0 /var/sites/o/oxfordriderwear.com/public_html/wp-includes/class-wp-hook.php(286): country_geolocated_based_hide_price('apply_filters('get_price_html() #4 /var/sites/o/oxfordriderwear.com/public_html/wp-content/plugins/woocommerce/includes/admin/list-tables/abstract-class-wc-admin-list-table.php(261): WC in /var/sites/o/oxfordriderwear.com/public_html/wp-content/themes/storefront/functions.php on line 61

我使用的代码有什么不正确的地方吗？或者我需要添加一些东西来解决这个问题，以便我的管理区域显示正常？

add_filter( 'woocommerce_get_price_html', 'country_geolocated_based_hide_price', 10, 2 );
function country_geolocated_based_hide_price( $price, $product ) {
    if( get_current_user_id() > 0 ) {
        $customer = WC_Customer(get_current_user_id());
        $country = $customer->get_billing_country();
    } else {
        // Get an instance of the WC_Geolocation object class
        $geo_instance  = new WC_Geolocation();
        // Get geolocated user geo data.
        $user_geodata = $geo_instance->geolocate_ip();
        // Get current user GeoIP Country
        $country = $user_geodata['country'];
    }
    return $country !== 'GB' ? '' : $price;
}

为避免此问题，我们可以 return 后端的格式化价格，如下所示：

add_filter( 'woocommerce_get_price_html', 'country_geolocated_based_hide_price', 10, 2 );
function country_geolocated_based_hide_price( $price, $product ) {
    // Not on backend
    if( is_admin() ) 
        return $price;

    if( get_current_user_id() > 0 ) {
        $country = WC()->customer->get_billing_country();
    } else {
        // Get an instance of the WC_Geolocation object class
        $geo_instance  = new WC_Geolocation();
        // Get geolocated user geo data.
        $user_geodata = $geo_instance->geolocate_ip();
        // Get current user GeoIP Country
        $country = $user_geodata['country'];
    }
    return $country !== 'GB' ? '' : $price;
}

代码进入您的活动子主题（或活动主题）的 function.php 文件。已测试并有效。

没有更多错误。
