从结帐页面隐藏帐单地址但保留信息

我想从结帐页面隐藏帐单地址（而不是删除它）并在注册时首次设置帐单地址？

允许在账单上显示.pdf

我添加这段代码：

<?php

add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

function custom_override_checkout_fields( $fields ) {
    unset($fields['billing']['billing_first_name']);
    unset($fields['billing']['billing_last_name']);
    unset($fields['billing']['billing_company']);
    unset($fields['billing']['billing_address_1']);
    unset($fields['billing']['billing_address_2']);
    unset($fields['billing']['billing_city']);
    unset($fields['billing']['billing_postcode']);
    unset($fields['billing']['billing_country']);
    unset($fields['billing']['billing_state']);
    unset($fields['billing']['billing_phone']);
    unset($fields['order']['order_comments']);
    unset($fields['billing']['billing_address_2']);
    unset($fields['billing']['billing_postcode']);
    unset($fields['billing']['billing_company']);
    unset($fields['billing']['billing_last_name']);
    unset($fields['billing']['billing_email']);
    unset($fields['billing']['billing_city']);
    return $fields;
}

通过添加此代码，帐单地址不会添加到 pdf 帐单中

那么我应该添加或编辑哪些代码？

先感谢您。

第一步：注册时首次设置帐单地址

1) 您需要更改 WooCommerce 设置才能注册。
WooCommerceSettings > Account (tab):

2）在用户注册中添加计费字段我的账户 page:

Base: 如何在“我的账户”页面的用户注册中添加自定义字段 https://support.woothemes.com/hc/en-us/articles/203182373-How-to-add-custom-fields-in-user-registration-on-the-My-Account-page

定制代码（将该代码复制到活动子主题或主题的 function.php 文件中）:

if( !is_admin() )
{
    // Function to check starting char of a string
    function startsWith($haystack, $needle)
    { 
        return $needle === '' || strpos($haystack, $needle) === 0;
    }

    // Custom function to display the Billing Address form to registration page
    function my_custom_function()
    {
        global $woocommerce;
        $checkout = $woocommerce->checkout();

        ?>
            <h3><?php _e( 'Billing Address', 'woocommerce' ); ?></h3>
        <?php

        foreach ($checkout->checkout_fields['billing'] as $key => $field) :
            woocommerce_form_field( $key, $field, $checkout->get_value( $key ) );
        endforeach;
    }
    add_action('register_form','my_custom_function');


    // Custom function to save Usermeta or Billing Address of registered user
    function save_address($user_id)
    {
        global $woocommerce;
        $address = $_POST;

        foreach ($address as $key => $field) :
            if(startsWith($key,'billing_'))
            {
                // Condition to add firstname and last name to user meta table
                if($key == 'billing_first_name' || $key == 'billing_last_name')
                {
                    $new_key = explode('billing_',$key);
                    update_user_meta( $user_id, $new_key[1], $_POST[$key] );
                }
                update_user_meta( $user_id, $key, $_POST[$key] );
            }
        endforeach;
    }
    add_action('woocommerce_created_customer','save_address');


    // Registration page billing address form Validation
    function custom_validation()
    {
        global $woocommerce;
        $address = $_POST;

        foreach ($address as $key => $field) :

            // Validation: Required fields
            if(startsWith($key,'billing_'))
            {

                if($key == 'billing_country' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please select a country.', 'woocommerce' ) );
                }

                if($key == 'billing_first_name' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter first name.', 'woocommerce' ) );
                }

                if($key == 'billing_last_name' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter last name.', 'woocommerce' ) );
                }

                if($key == 'billing_address_1' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter address.', 'woocommerce' ) );
                }

                if($key == 'billing_city' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter city.', 'woocommerce' ) );
                }

                if($key == 'billing_state' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter state.', 'woocommerce' ) );
                }

                if($key == 'billing_postcode' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter a postcode.', 'woocommerce' ) );
                }

                if($key == 'billing_email' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter billing email address.', 'woocommerce' ) );
                }

                if($key == 'billing_phone' && $field == '')
                {
                    $woocommerce->add_error( '' . __( 'ERROR', 'woocommerce' ) . ': ' . __( 'Please enter phone number.', 'woocommerce' ) );
                }
            }

        endforeach;
    }
    add_action('register_post','custom_validation');

}

第二步：在结帐时隐藏帐单地址而不将其删除

您将需要使用 CSS 来定位计费块字段display: none !important; rule.
