Okay– I know that not allowing updates is a cardinal sin as this prevents security patches, bug fixes, etc. BUT I had to alter some of the code in the RSVP.php file (which generates the tickets) so that I could achieve the desired functionality for the client. This is really the only way that I could get what I needed to work to work (as I don’t believe PHP allows you to override functions in the same way as Java).
Now is there anyway to write in a hook to take away the ability for the client to upgrade this plugin by mistake?
Again, I know this is terrible practice and if anyone has another suggestion how to edit plugin functionality (besides the page templates), that won’t be overridden with plugin updates, I am all ears!
