Adding fields to topics/posts

[logii]

Is there anyway to add new fields to topics or posts for custom sorting?

There is no way to do this in core. Are you trying to make a plugin to do this?

For adding fields to a post/topic you would use the hooks as so:

Sorting is another matter, you need to also add the fields to a sortedSet in the db, here are two examples:

https://github.com/wktang/nodebb-plugin-category-sort-by-votes

You mean add tags after the fact? Only a mod or the OP can edit a topic and add them.

Tags are not available for posts but I really, really, wish they were.
