WP_Query仅凭ID？

any应该检索任何类型:

 $args = array(
  'p'         => 42, // ID of a page, post, or custom type
  'post_type' => 'any'
);
$my_posts = new WP_Query($args);
 

请注意文档中any的说明:

'any'-检索除修订和'exclude_from_search'设置为true的类型以外的任何类型.

有关更多信息,请参阅 WP_Query 的文档.

  'p'         => 42, // ID of a page, post, or custom type
  'post_type' => 'any'
);
$my_posts = new WP_Query($args);

Note the description of any in the documentation:

'any' - retrieves any type except revisions and types with 'exclude_from_search' set to true.
