wp_transition_comment_status: 当一个评论的状态发生变化时,例如从待定到批准,这个函数会触发行动。

当评论状态转换发生时,调用钩子。

调用评论状态转换的钩子。如果新的评论状态与之前的评论状态不一样,那么将运行两个钩子,第一个是{@see ‘transition_comment_status’},包含新状态、旧状态和评论数据。接下来调用的动作是{@see ‘comment_$old_status_to_$new_status’}。它有评论数据。

最后一个动作将运行评论状态是否相同。
这个动作被命名为{@see ‘comment_$new_status_$comment-> comment_type’}。
