如何为 bbPress 论坛添加” 新贴” /「热帖」 / ” 置顶帖” 标签功能?

//bbPress 添加置顶标签

function rk_sticky_topics() {
  
   if ( bbp_is_topic_sticky() && !bbp_is_topic_closed() )
      echo '<span class="sticky">[Sticky]</span>'; //可根据需要修改文字内容
}
  
add_action( 'bbp_theme_before_topic_title', 'rk_sticky_topics' );

//bbPress 添加关闭标签
function rk_closed_topics() {
  
   if ( bbp_is_topic_closed() && !bbp_is_topic_sticky() )
      echo '<span class="closed">[Closed]</span>';
}
  
add_action( 'bbp_theme_before_topic_title', 'rk_closed_topics' );

//bbPress 添加新话题热帖标签
function rk_hot_topics() {
   $reply_count = bbp_get_topic_reply_count();
  
   if ( $reply_count > 25 ) //回复超过 25 个为显示热帖
      echo '<span class="hot">[Hot]</span>';
}
  
add_action( 'bbp_theme_before_topic_title', 'rk_hot_topics' );

//bbPress 添加新话题帖子标签
function rk_new_topics() {
$offset = 30*30*1; //时间间隔，单位为秒

   if ( get_post_time() > date('U') - $offset )
      echo '<span class="label label-new">[New]</span>';
}

add_action( 'bbp_theme_before_topic_title', 'rk_new_topics' );
