临时解决方法

在继续操作之前，请确保对您的站点进行了完整站点备份。

• 打开 …/wp-content/plugins/wp-event-manager-registrations/wp-event-manager-registrations-functions.php 文件。


• 找到第 497 行。


• 将：

  if(!function_exists('get_event_registration_count')) {
      /**
       * Get number of registrations for a event
       * @param  int $event_id
       * @return int
       */
      function get_event_registration_count($event_id) {
          return sizeof(get_posts(array(
              'post_type'      => 'event_registration',
              'post_status'    => array_merge(array_keys(get_event_registration_statuses()), array('publish')),
              'posts_per_page' => -1,
              'fields'         => 'ids',
              'post_parent'    => $event_id
          )));
      }
  }



• 替换为：

  if(!function_exists('get_event_registration_count')) {
      /**
       * Get number of registrations for a event
       * @param  int $event_id
       * @return int
       */
      function get_event_registration_count($event_id) {
          
          // WPML workaround for compsupp-7562 - Part I
          $element_type = 'post_' . get_post_type( $event_id );
          $trid = apply_filters( 'wpml_element_trid', null, $event_id, $element_type );
          $translations = apply_filters( 'wpml_get_element_translations', null, $trid , $element_type );
          
          // Extract the IDs of the translated posts
          $event_ids = array_map(function($translation) {
              return $translation->element_id;
          }, $translations);
      
          // Get event registrations for all translations
          return sizeof(get_posts(array(
              'post_type'      => 'event_registration',
              'post_status'    => array_merge(array_keys(get_event_registration_statuses()), array('publish')),
              'posts_per_page' => -1,
              'fields'         => 'ids',
              'post_parent__in' => $event_ids // Get all registrations for the event IDs
          )));
      }
      
  }



• 然后，找到第 595 行。
