My plugin needs to store a value (timestamp) in the database. The value isn’t associated with any post/page/etc. Its associated with the plugin. Where should I write this value to the database – what table?
I’ve used add_post_meta(); before and this works well to store information associated with a post/page. Is there something similar to write plugin specific information? Maybe a add_plugin_meta()?
