I think part of the reason that consolidating multiple options into a
single array is considered best-practice now, is *because of* the
current state of option chaos. That, and the fact that you don't have to
make 10 separate db calls to get 10 different options. But if the
options were namespaced consistently you could just SELECT ... WHERE
option_name LIKE 'plugin:foo-plug:%' and get all your info in one call
Regardless, even if everyone used an array for all options (which is
fine for probably 99% of the plugins out there), the namespacing idea
would still make it easier to make sense of things in those rare cases
when you have to dive directly into the table for some reason.
Again, I'm not sure whether or not its an idea worth trying to champion.
But at the least, I figure it's at least worth seeing if some more solid
best-practices could be extracted from the discussion. Currently
(AFAIK), the extent of best-practices around saving options is "store
all values together in an array whenever possible" and "prefix your
option name", with little guidance as to a prefix format.
Do we *need* to define a suggested prefix format? I dunno -- maybe it's
overkill. There's no easy way to enforce it without making changes to
core (though I have some ideas about that). Would a consistent prefix
format be useful? That's what I'd like us to discuss.
