因此，我的自定义帖子类型中的自定义字段有问题。无论出于何种原因，字段都会随机保存并清除。。。我肯定这不是随机的，但我不确定是什么触发了这种情况的发生。以下是我自定义帖子类型的代码：

    // Custom Post Type: Strategic Giving
add_action(\'init\', \'giving_register\');

function giving_register() {

  $labels = array(
    \'name\' => _x(\'Invest Items\', \'post type general name\'),
    \'singular_name\' => _x(\'Item\', \'post type singular name\'),
    \'add_new\' => _x(\'Add New\', \'giving item\'),
    \'add_new_item\' => __(\'Add New Item\'),
    \'edit_item\' => __(\'Edit Item\'),
    \'new_item\' => __(\'New Item\'),
    \'view_item\' => __(\'View Item\'),
    \'search_items\' => __(\'Search Items\'),
    \'not_found\' =>  __(\'Nothing found\'),
    \'not_found_in_trash\' => __(\'Nothing found in Trash\'),
    \'parent_item_colon\' => \'\'
    );

  $args = array(
    \'labels\' => $labels,
    \'public\' => true,
    \'publicly_queryable\' => true,
    \'show_ui\' => true,
    \'query_var\' => true,
    \'menu_icon\' => get_stylesheet_directory_uri() . \'/images/cpt-giving.png\',
    \'rewrite\' => array( \'slug\' => \'giving_items\' ),
    \'capability_type\' => \'post\',
    \'hierarchical\' => true,
    \'menu_position\' => null,
    \'supports\' => array(\'title\',\'thumbnail\',\'editor\'),
    \'paged\' => false,
    ); 

  register_post_type( \'givings\' , $args );
}

register_post_type( \'givings\' , $args );

      Strategic Giving photo must be horizontal and uploaded/set as the <strong>Featured Image</strong> (see below).

是否可以仅为单个帖子类型而非全局关闭autosave？
