You want to be able to have a Custom Filter (in the Front End) by Taxonomy A, while Viewing a Loop of items in taxonomy B?
You could do that in a Post View, where you add filters by Taxonomies, would that not solve the issue?
What exactly would can you not achieve due to this missing feature?
Maybe I can help to find another solution.
Hi
Here is my test page: hidden link This is a film festival website archive.
Film titles on the left, filters on the right sidebar (year, film category).
The film categories change every year. For example in 2016 there is only "Animációs film" category.
I made two filter versions for fim category. The second I would prefer but here I can not set it to show only the film categories of the selected year. This taxonomy view (screenshot) show all the film categories of all years.
"Only Views listing posts can have custom search inputs."
In the second filter version I like to display the number of posts 🙂
What is "Year"?
A taxonomy as well?
This kind of search is no problem to achieve, you just create a Custom Post type, and 2 taxonomies, or 2 fields, which hold the "Film category" and the "Year" information.
With an "AJAX update when the filter input values change", this kind of search would then output just possible search results for year 2016, means, just one taxonomy, for example.
Do you want me to split this ticket and show you how in another, technical assistance thread?
