I think I'm finally getting a grip on plugins, which is a kind way of saying I don't know what I'm doing. I know what I *want* to do though.

So I'm trying to make a plugin. A contest plugin that bloggers will be able to post entries into. So far it's a toolbar that lets them select and enter stuff, a renderer that puts a comment into the post (in the form of <!-- foo -->), a tab that lets me add options as need be, and a database to store the info upon entry. That's where I'm stuck. I can't see how to make a plugin add info to the database upon posting. RenderItemAsHtml isn't the right place for it because that would mean each view would add the same content again and again, though I think a brute force answer could be found. (If the db doesn't have this exact info then add it.)

For what I'm doing I can live without giving edit permission, but ideally the plugin would allow editing the info in the post - and maybe even deleting it. So to me that rules out RenderItemAsHtml because it has to pay attention to if we're posting or editing.

Does anyone know of a plugin that does something like this? If so I'll add it to the list of plugins I take apart to make this one happen.
