I'm trying to write a plugin that uses a custom filter hook and I cannot seem to get it to work. It's been a while since I've written any plugin code, but as far as I can tell I'm doing all the right things, so I can't figure out what's wrong. Hopefully someone here can help me out.
It's also quite possible that I'm doing it wrong from a PHP perspective.
In order not to clutter the post I've posted pseudocode as a gist at https://gist.github.com/1272309 but essentially I'm calling apply_filter with a hook name and hooking into it in a static method on another class. As far as I can tell (via logging to a text file) the startup/filter hooking code is working properly, but my filter handler's not ever being called.
Thanks in advance for any suggestions!
