programming: how to append tag to post with some criteria?
I am writing plugin. I want to add tag “video” to post, when it is published or edited if this post has some special value in Custom Field.
I know how to check if post has this custom field.

but i don’t know how to add tag ‘video’ in this action. what should be in function?
