I'm working on an administration panel for a theme I'm developing. The task I am working on now is adding a "Screen Options" tab for a list table. I have the page load hook in place, and the
per_page box shows up in the panel as expected. However, the filter (as advised by several tutorials online)
set-screen-option that I'm hooking into is never being called when I submit the form. It stays at
10 (the default), and doesn't save what I enter. I've tested, and the filter I define isn't called at all. I even added another filter to it with an anonymous function that does nothing but echo content. No output.
Where am I going wrong? Thank you!
