Dynamic dependant filters

Yes, it's possible. Just enter the first filter identifier as "Arguments for the view" setting of the second filter (surrounded in [] brackets).

You have two filters: master and dependent. You need to know master filter identifier (e.g. field_master). When you configure the dependent filter (which is Views Reference Filter), you must enter [field_master] in the "Arguments for the view", and create new view which receives one argument (which will be the current value of the master field), this view must be selected in "View used to select the entities" in the dependent filter configuration.

Have you solved your problem?

Hi,

for me, this is also somewhat sketchy on what to do exactly. I'm trying to get this dependent filter working, but it doesn't seem to work.

Following content types:
Season
Competition ( Entity reference: Season)
Matchday (Entity reference: Competition)

I made a view where I can view my matchdays with following filters:

With dependee filter "Season":

And Dependent filter "Competition"

Following is my contextual filters for the entity_reference view:

An example of my exposed filters:

The thing is when I'm looking at my entity_reference view argument I don't see anything:

function mytheme_views_pre_render (&$view) {
  if($view->name == 'references_view') {
    dpm($view->argument);
  }
}

Hoping to inform you enough, I would like to know whether this is a bug, or is it me that is implementing it wrong?

Thanks in advance!

Could you check whether AJAX call is performed when the master filter is changed?

How to check whether AJAX call is performed?
I followed the instructions, but the list of options for dependent filter is not updated. Only after I press Apply button it's updated.

Use Network tab of web development tools of your browser.

Does it needs an AJAX call then? My page just refreshes...
If the page gets refreshed after applying the first filter, shouldn't the second filter automatically get it's argument from the first filter?

My second filter gets "All" as argument, always.

Oh. Could you disable page reloading after changing the first filter (turn form autosubmit off)?

So there happens something... but only for the field_season_target_id, I don't get any responses to change the competition select box.

My form setup:

I think everything works. What is the problem?

The problem is that my second (dependant) select is not being updated...

Could you try the latest version? I fixed some bugs there.

For anyone beating their head against this same issue like I was, I found a hint in another issue: the preview screen does not show the desired behavior of these screenshots, but it DOES work on the view page itself (or pane, in my case). See screenshots below.

One note on the Contextual Filter settings for the Reference Filter View: I did not want this view (country) to show up at all unless the user had already selected the parent filter (region), hence my configuration:

WHEN THE FILTER VALUE IS NOT AVAILABLE: Display contents of "No results found"

Hide View did not work for me in this use case: it hid the view no matter what the parent filter selection. No results hid it only when a region was not selected.

If you do this, you will not see the dependent filter in the preview AT ALL due to the default checkmark "Hide filter if empty." I unchecked this item just for this screenshot just for demonstration purposes. However, for production, I will check it so that the country selector is not shown at all unless it is populated per the region selected.
