Support » Plugin: Widget Logic » Parent and child categories

  • Hi! I’m trying to get my widget to show up only in the following places:
    – on a specific category page
    – on any post within that category
    – on any post within a child of that category

    I’ve got 2/3, but that last one has eluded me, despite much scanning of the Codex and Googling.

    What I have now:
    is_category(5) || (is_single() && in_category(5))

    I’ve tried the post_is_in_descendant_category function described here:

    but that broke my blog (after adding the relevant code to functions.php and updating the widget logic, I only got a blank page on refresh).

    Is this possible and, if so, please describe what I should be doing?

    Many thanks!
