Hello Francesco.

Sorry to disappoint you but unfortunately the cascade filtering is working on "change" of the filters and it is not possible to pass the value for the filter in the URL so the other columns will be filtered as well depending on chosen cascade logic.

The logic and the development of the cascade filtering is that the filter needs to trigger a change of the data in the filter, so it can not be passed via URL.

Probably this can be achieved with some Javascript running on the page but unfortunately writing the scripts is something that is not covered with the included support of the product.

Maybe the workaround would be to write a script that on window load, or document ready, get the desired data from the URL and then change the statement in the filter.

Hi again Francesco

wpDataTables doesn't have any APIs yet. We'll most likely include it in one of our future updates, but there's no ETA on that yet.

I wouldn't advise modifying any Javascript files of the plugin, but instead create a custom JS that would be added to the page in order to perform this.

You can take a look at our filters and hooks and see if that helps. When you add the code to either the page, or functions.php file of your theme (or child theme), plugin's updates won't mess it up since you'd be using hooks that are a part of the code already.
