Category Selective Announcements

[Wormopolis]

Browser Tested: IE and FF
placement: 3 parts, global header/footer and main footer.

This code will let you set up an announcement to show only in boards of a specified category, and hidden everywhere else. It will not override the "show announcements" settings in the board setups.

On the first post of an announcement, it will provide a list of checkboxes for each category). replies will not have access to the checkboxes - modifications can only be made from the first post.


Global Header portion: (place as high up as possible)

Preview: eventually, but basically it hides the announcement unless you click the checkboxes telling it to show it.

ok.. so something I hadn't considered. if you have categories that only certain members can see, this code wont work for you. It basically takes note of the order your categories appear in the forum jump. so if you say you want an announcement to appear in the first 3 categories, then it will for you. if another member doesnt have access to that category for whatever reason, then it will show in the first 3 categories that THEY have.

there is no way to store categories by name because the thread title can only hold so many characters. that is why I went with the order they appear.
