i have a filter search on the left of the page (with checkboxes), and the results on the right. when i’m testing checking only certain boxes (topics) it always shows all the results
all the items are linked to categories. I’m also getting an issue where there are only 2 showing up when all the checkboxes are ticked, or if i’ve ticked 2 options (and i know there are 4 posts in these in total), i’m only getting 2 results.
Okay, in that case I suspect the incorrect logic is used. By default when a checkbox is unchecked, then it is treated as exclusion – so anything belonging to that category (even if belonging to other categories) is excluded.
Try this logic instead.
