WP：mysql查询：将帖子添加到多个类别中的类别

Question

我找到了一个用于将帖子添加到另一个单一类别中的类别的 sn-p：

# remember to replace @CategoryID and @OldCategoryID.   @OldCategoryID is in the middle
INSERT INTO wp_term_relationships (object_id, term_taxonomy_id, term_order) 
  SELECT object_id, @CategoryID, 0 FROM wp_term_relationships tr2 
    WHERE tr2.term_taxonomy_id = @OldCategoryID AND object_id NOT IN 
      (SELECT object_id FROM wp_term_relationships tr3
        WHERE tr3.term_taxonomy_id = @CategoryID);

但是我无法让它适用于一系列类别的帖子。

所以这不起作用：

INSERT INTO wp_term_relationships (object_id, term_taxonomy_id, term_order) 
  SELECT object_id, 101, 0 FROM wp_term_relationships tr2 
    WHERE tr2.term_taxonomy_id IN (61,62,63,64,65) AND object_id NOT IN 
      (SELECT object_id FROM wp_term_relationships tr3
        WHERE tr3.term_taxonomy_id = 101);

为什么不使用 wordpress 内置函数 wp_insert_post()

来自 wp 的示例：

// Create post object
$my_post = array(
  'post_title'    => wp_strip_all_tags( $_POST['post_title'] ),
  'post_content'  => $_POST['post_content'],
  'post_status'   => 'publish',
  'post_author'   => 1,
  'post_category' => array( 8,39 )
);
 
// Insert the post into the database
wp_insert_post( $my_post );
