Adding custom attributes to comments
Jamroom Developers
Threading is already an option of the jrComments module.
ACP -> MODULES -> ITEM FEATURES -> COMMENTS -> GLOBAL CONFIG -> LIST OPTIONS -> ENABLE THREADING
In answer to the question though: You can add anything you like to any items datastore, but it must be prefixed with the modules prefix. For the comments module, that's 'comment_'.
You can add any extra fields you like to an item, they're just stored as KEY : VALUE pairs that become available in the templates along with the rest of the items info.
Looking.
