Problem : Add checkbox filter for parent custom taxonomies.
I did research to achieve above goal but did not found anything to Add checkbox filter for parent custom taxonomies.

Solution : I have added custom dropdown field for each post type named as "Select parent category".
Now, to show parent custom taxonomies as dropdown options I have added below code.

add_filter('wpt_field_options', 'fill_select', 10, 3);

function fill_select($options, $title, $type) {

    if ($title == 'Select Parent Category') {
        $args = [
            'taxonomy' => 'location-type',
            'parent' => 0,
            'hide_empty' => false
        ];
        $terms = get_terms($args);
        $options[] = array(
            '#value' => 0,
            '#title' => "Select",
        );
        foreach ($terms as $term) {
            $options[] = array(
                '#value' => $term->name,
                '#title' => $term->name
            );
        }
    }
    return $options;
}

I have added filter using custom dropdown field "Select parent category".
But I am not able to see the values and checkboxes.

One thing I have noticed is, If i add dropdown option using toolset it is working fine.

Thanks

Hello. Thank you for contacting the Toolset support.

Well - 'wpt_field_options' filter will not work in this case.

As I understand, you want to display only parent terms using view's taxonomy filter - correct?

[marcB-6]

Yes

[Minesh]

what you need to do is - you need to add your taxonomy filter normal way but you need to add custom jQuery code to your view's filter JS box and delete the all options that are child.

Please check this related solution - this is for select box:

Ok thanks, but I am not selecting parent taxonomy when I am creating post. I am selecting child taxonomy while adding post. Now I would like to add checkbox filter for parent taxonomy.

For example,
Restaurants ===> Parent
- Indian ===> Child
- Italian ===> Child
Watersports ===> Parent
- scubadiving ===> Child
- kitesurfing ===> Child

When I am adding post called "Taj Hotel" I am selecting "Indian" as custom taxonomy..Now I would like to add filter checkbox for "Restaurants","Watersports".

As I am not selecting parent taxonomy while creating post I will not get "Taj Hotel" when I check "Restaurants".

Please let me know How to do this

[Minesh]

No - when you will add taxonomy filter normally to your views - to display all taxonomy terms, navigate to:
=> Custom Search Settings => Let me choose individual settings manually => set option "Always show all values for inputs"

So - it will display all taxonomy terms with your taxonomy dropdown, now, you should follow the way I suggested using jQuery to remove unwanted terms from your taxonomy filter drop-down.

Yes I have followed below steps
=> Custom Search Settings => Let me choose individual settings manually => set option "Always show all values for inputs"
Its working..Thanks for your support.

Thanks

Its working But I have around 150 taxonomies..So Do I need to add all in to an array as mentioned here : https://toolset.com/forums/topic/parametric-search-with-only-parent-taxonomy-on-pulldown-menu/#post-465858

This is not proper way to do. In future If I add 50 more then I need to add those as well..

Is there any other solution?

[Minesh]

Well - this is not normal situation as filter will work for selected taxonomy term.

You should try to use view's hook wpv_filter_query and check if "include_children" is set to 1.

For example:

add_filter( 'wpv_filter_query', 'show_parent_recoreds', 10, 3 );
function show_parent_recoreds( $query_args, $settings, $view_id ) {
        if($view_id == 9999){
              $query_args['tax_query'][0]['include_children'] = 1;
            
    }
    return $query_args;
}

Where:
-- Replace '9999' with your original view ID
-- Adjust the code as needed

Does this help?

[Minesh]

Well - there is no dynamic solution available.

You need to follow the way I already suggested here:

I have put code given by you above.
As you see in attached screenshot, There are two filter added for two different taxonomies.
When I am doing

echo "<pre>";
    print_r($query_args);

I see only 1 taxonomy in tax_query that is location-theme.
I have another taxonomy as well which is location-types which I can not see when I am printing $query_args

[Minesh]

OK - as I can see "include_children" is already set to 1, so no change needed. Now, regarding two taxonomy filter arguments, I can see that another taxonomy filter is setup using URL parameter. did you selected anything from your another taxonomy filter. If yes - it should show it, if no, it will not show it.

Please tell me what is your exact need.

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).

I have set the next reply to private which means only you and I have access to it.
