I've got a publish with multiple publish tags connected by using it. Within the publish-edit form, inside a textarea named "publish_tags" I'm exhibiting these questions comma separated string. Now I want the next:

  1. If user give a new keyword it will likely be put into wordpress_terms and connected using the publish.
  2. If user removes any term from that list it'll just dissociate it in the post's association and won't remove in the wordpress_terms table.

I've handled to complete the very first point however i am tied to the 2nd. Doe anybody have good idea to beat this case?
