您必须查询未附加帖子格式的帖子：

$args = array(
  \'post_type\' => \'post\',
  \'tax_query\' => array(
    array(
      \'taxonomy\' => \'post_format\',
      \'field\' => \'slug\',
      \'operator\' => \'NOT IN\',
      \'terms\' => get_terms(\'post_format\')
    )
  )
);

为了提高性能，您可以对post格式进行硬编码，而不是使用get_terms 要检索它们，请执行以下操作：

$args = array(
  \'post_type\' => \'post\',
  \'tax_query\' => array(
    array(
      \'taxonomy\' => \'post_format\',
      \'field\' => \'slug\',
      \'operator\' => \'NOT IN\',
      \'terms\' => array(\'post_format-aside\',\'post_format-chat\',\'post_format-gallery\',\'post_format-link\',\'post_format-image\',\'post_format-quote\',\'post_format-status\',\'post_format-video\',\'post_format-audio\')
    )
  )
);

一旦您在注释中请求它，我将为您提供可以执行相同任务的原始SQL查询。请注意，一旦没有post格式的post没有存储在任何地方（标准post格式意味着没有post格式），要获得所需的内容，您需要嵌套2个查询，其中嵌套的查询包含3个表之间的联接。这远远不是所谓的性能查询。为此，最好将结果缓存在瞬态中：

function post_without_formats() {
    $cached = get_transient(\'post_without_formats\');
    if ( $cached ) return $cached;
    global $wpdb;
    $post_without_format = $wpdb->get_results(
      "SELECT * FROM $wpdb->posts WHERE post_status = \'publish\'
       AND post_type = \'post\' AND ID NOT IN (
         SELECT p.ID FROM $wpdb->posts as p
         LEFT JOIN $wpdb->term_relationships as tr ON tr.object_id = p.ID
         LEFT JOIN $wpdb->term_taxonomy as tt ON tt.term_taxonomy_id = tr.term_taxonomy_id
         WHERE p.post_status = \'publish\' AND p.post_type = \'post\'
         AND tt.taxonomy = \'post_format\'
         GROUP BY p.ID
       )"
    );
    set_transient(\'post_without_formats\', $post_without_format);
    return $post_without_format;
}

function reset_post_without_formats($term, $taxonomy) {
  if ( $taxonomy == \'post_format\' ) {
    delete_transient(\'post_without_formats\');
    post_without_formats();
  }
}

add_action(\'edited_term_taxonomy\', \'reset_post_without_formats\', 99, 2);

正如您所看到的，每次在帖子中添加或删除帖子格式时，我都会重置瞬态。这将使后端速度降低一点，但会提高前端速度。
