您可以尝试使用wp_insert_post_data 对于任务。类似于：

function assign_new_post_to_specific_author( $data , $postarr ) {

  // Where author_ID is the ID of the author you want to assign the new post
  $data[\'post_author\'] = author_ID; 

  return $data;

}

add_filter( \'wp_insert_post_data\', \'assign_new_post_to_specific_author\', \'99\', 2 );
