What would you like to do?
A work in progress abstraction that will allow user meta for all users including guests. Please contribute.
<?php
namespace storyteller;
/**
* This is a class designed to be used in WordPress Plugins and Themes where for
* whatever reason, the designer wishes to track a huge ammount of per-user data
* and keep it well ordered and accessable.
*
* I am posting this in an incomplete state; in the hope that further developers
* might have ideas that will finish the project for the good of the community.
*
* This is part of a wider project to use WordPress for interactive fiction as a
* form of storytelling. Thus the namespace.
*
* Datastore is an abstraction layer to store data within user_meta or elsewhere
* against guest_cookie (in site_meta) which requires garbage collection.
*
* datastore is intended to query the data quickly. For example via a number of
* shortcodes and assorted API yet to be created. It should be possible to ask a
* question about the data without any awareness beyond getting TRUE or FALSE as
* a return value. Thus, datastore::test_var(...);

* Where to put guest user data?
* -----------------------------
*
* All signs point to abusing existing API as a very bad idea.

*
* This may require the creation of a session meta_table of some kind.

I think I have an answer in the form of a one-file plugin that I wrote called Guest Meta.
