   //1. ADD OPT IN OPTION IN CHECKOUT AND SAVE IN THE ORDER
   
   // Add checkbox optin before T&Cs
   add_action( 'woocommerce_checkout_before_terms_and_conditions', 'marketing_opting_field' );

   // 2. SHOW CUSTOM COLUMN FOR THE OPTIN OPTION
   
   // Adding custom column title
   add_filter( 'manage_edit-shop_order_columns', 'custom_shop_order_column', 12, 1 );
   function custom_shop_order_column($columns)

       $action_column = $columns['order_actions'];
       unset($columns['order_actions']);
   
       //add the new column "Opt in"
       $columns['order_marketing'] = '<div align="center">' .__("Opted in?") . '</div>'; // title
       $columns['order_actions'] = $action_column;

       if ($column ==='order_marketing') { 
           $value = $the_order->get_meta( '_marketing_opting' );
           $label = $value === 'yes' ? __('Signed Up') : ucfirst($value);
           $color = $value === 'yes' ? 'color:#00cc00;' : 'color:#bbbbbb;';
   
           echo '<p align="center" style="'.$color.'"><span class="dashicons dashicons-'.$value.'"></span><span style="font-weight:600;">'.$label.'</span></p>';
       }
   }
   
   // 3. Make marketing optin meta searchable from search field (can't work very well for 'yes' or 'no' values!)
   
   // Make a custom meta field searchable from the admin order list search field
   add_filter( 'woocommerce_shop_order_search_fields', 'marketing_search_fields', 10, 1 );
   function marketing_search_fields( $meta_keys ){
       $meta_keys[] = '_marketing_opting';
       return $meta_keys;
   }
   
   // 4. Add a dropdown filter to get orders by marketing optin meta value
   
   // Add a dropdown to filter orders by Marketing optin
   add_action( 'restrict_manage_posts', 'display_admin_shop_order_marketing_opting_filter' );
   function display_admin_shop_order_marketing_opting_filter(){
       global $pagenow, $post_type;
   
       if( 'shop_order' === $post_type && 'edit.php' === $pagenow ) {
           $domain    = 'woocommerce';
           $current   = isset($_GET['filter_shop_order_marketing'])? $_GET['filter_shop_order_marketing'] : '';
   
           echo '<select name="filter_shop_order_marketing">
           <option value="">' . __('Filter Marketing optin', $domain) . '</option>';
   
           $options = ['yes' => __('Signed Up'), 'no' => __('No')];
   
           foreach ( $options as $key => $label ) {
               printf( '<option value="%s"%s>%s</option>', $key, 
                   $key === $current ? '" selected="selected"' : '', $label );
           }
           echo '</select>';
       }
   }
   
   // Process the filter dropdown for orders by Marketing optin
   add_filter( 'request', 'process_admin_shop_order_marketing_opting_filter', 99 );
   function process_admin_shop_order_marketing_opting_filter( $vars ) {
       global $pagenow, $typenow;
   
       if ( $pagenow == 'edit.php' && isset( $_GET['filter_shop_order_marketing'] ) 
           && $_GET['filter_shop_order_marketing'] != '' && 'shop_order' === $typenow ) {
           $vars['meta_key']   = '_marketing_opting';
           $vars['meta_value'] = wc_clean( $_GET['filter_shop_order_marketing'] );
       }
       return $vars;
   }
   

   참고 : 나는 Meta_Key를 다른 기존 metakeys로 밑줄로 시작하는 meta_key를 _marketing_opting으로 변경했습니다 ...

   또한 주문을 한 고객을 위해 WC () -> 체크 아웃 -> GET_VALUE ( 'marketing_opting')의 체크 아웃에서 사용자 메타 데이터에 "마케팅 Optin"값을 등록하는 함수를 추가했습니다.

   코드는 Active Child Theme (또는 활성 테마)의 functions.php 파일입니다. 테스트하고 작동합니다.
