您可以添加meta_框，以便将自定义字段数据存储在其中。自从add_meta_box 可以根据post\\u类型进行设置这将允许您向不同的post类型添加不同的meta\\u框。

看看这个post 有关更改自定义帖子类型新建/编辑屏幕的完整示例。

我最近需要在一个主题中解决一个非常类似的问题。代码的基础是post 我修改了一些代码

下面是我修改的代码的第一部分。

    add_action(\'init\', \'limited_post_type\');
function my_custom_limited_post_type() 
{
  $labels = array(
    \'name\' => _x(\'Limited Post Type\', \'post type general name\'),
    \'singular_name\' => _x(\'Film - DVD\', \'post type singular name\')
  );
  $args = array(
    \'labels\' => $labels,
    \'public\' => true,
    \'publicly_queryable\' => true,
    \'show_ui\' => true, 
    \'query_var\' => true,
    \'rewrite\' => true,
    \'capability_type\' => \'post\',
    \'hierarchical\' => false,
    \'menu_position\' => null,
    \'supports\' => array(\'title\',\'editor\',\'author\',\'thumbnail\',\'excerpt\', \'page-attributes\',\'custom-fields\' ),
    \'show_in_nav_menus\' => true
  ); 
  register_post_type(\'limited_post_type\', $args);
}

foreach ( $scope as $scopeItem ) {
       switch ( $scopeItem ) {
           case "post": {
             // Output on any post screen
             if ( basename( $_SERVER[\'SCRIPT_FILENAME\'] )=="post-new.php" || $post->post_type=="post" )
             $output = true;
             break;}              
            case "page": {
                  // Output on any page screen
                  if ( basename( $_SERVER[\'SCRIPT_FILENAME\'] )=="page-new.php" || $post->post_type=="page" )
            $output = true;
            break;}
             case "limited_post_type": {
                                // Output on limited post_type onlye
            if ((basename( $_SERVER[\'SCRIPT_FILENAME\'] )=="post-new.php" && $post->post_type=="limited_post_type" ) || (basename( $_SERVER[\'SCRIPT_FILENAME\'] )=="post.php" && $post->post_type=="film_dvd" ))
                   $output = true;
                   break;
                  }
