Option to show/hide widget depending on is_home?

Question

Is it possible to add a checkbox to all widgets loaded into sidebars? For example, I'd like to allow the site owner to choose whether any widget should appear on the home page, inside pages, both or neither.

I'm thinking a checkbox interface appended to the widget control interface.

Has anyone done something like this and what level of complexity are we talking?

Answer 1

There are plugins that can do this like Widget Context or Widget Logic.

If you want your own solution then it's pretty easy:

• hook your function with the checkbox on in_widget_form
• hook your widget update function widget_update_callback (update the widget option)
• check if the option was checked using the widget_display_callback hook (return false if it is)

Post what you have so far if you need sample code. I've implemented a feature like this in one of my themes...
