php - Rating and Like System Managment -

-


i'm trying integrate rating , system part of package send end user(with unknown progamming skill).
problem how manage users(registered or not) have done action.
at moment i'm using php session keep stored week information, isn't solution.
is solution creating 2 tables (one rating , 1 like) store information? if use solution what's usefull , "correct" information retrive if user not registred? , user-friendly?
i have thought store: username , ip
thanks

i extend members's table @ least 2 new columns, likes , rating or create new table (as said) including memberid reference(and index) store , select data. believe it's best way. unfortunately, in case non-members cannot press or rate, reason 1 register. –
