drmike,
What I am trying to do is to understand how I can add new url parameters for my plugins to perform certain actions.
Currently I have been working on a sitewide tagging system (as a lot of people lately have been doing) which is almost finished and a plugin which allows for a sitewide category menu. Both were requested by my client and are also sponsored by my client and will be made open under a GPL license. However, I can't seem to find a reliable way to create links for my plugins without hacking core files, which I prefer not to do unless my changes are committed back into the core and keep updating an easy process.
Basically this is what I want:
domain.tld/queryparameter/queryvalue
more or less the same as:
domain.tld/index.php?queryparameter=queryvalue
This would trigger a certain callback in my plugin and the action will be processed.
Is this possible or does Wordpress MU need a patch for this to be possible? I belief that this kind of functionality would allow plugin developers to enhance WP (MU) in all sorts of way and I would like to work on this with some guidance from this community.
I'm curious as to what other people think of this.
