Plugins: An Example (*) in Development Posted December 29, 2014 1) No. You would need to distribute a plugin with the theme. Though that would be a strange thing to do - if you're creating a theme, you can just add a message where you want it in the theme's HTML code. Remember that plugins will affect every theme.2) Usually no.3) It's possible if we move elements around that hooks on those elements will need to be updated. It would depend on the nature of the change.4) If you have manually modified the HTML of a template, it will be the same as in 3 (not upgraded and a diff report would typically be done). If a template is being modified by a hook, it will be updated as normal. A template is not generally aware if it has a hook on it.Thanks for reply.Idea I had then would not be of any use as a hook then if (1) is no, shame really but there you goI understand would be a strange thing to do but I have my reasons for it that way instead of manually editing template directly.
