Problem:

The issue here is that the user wanted to filter out their posts that have an empty date field.

Solution:

This can be done with the code below.

add_filter( 'wpv_filter_query', 'filter_empty_dates', 99, 3 );
    
function filter_empty_dates( $query_args,$view_settings ,$view_id ) {
       
    if ( $view_id == 503724) {
        $query_args['meta_query'] = array(
          'relation' => 'AND',
          array(
            'key' => 'wpcf-exam-date',
            'value' => '',
            'compare' => '!='
            ),
          array(
            'key' => 'wpcf-exam-date',
            'value' => time(),
            'compare' => '>='
            )
          );
    }
    return $query_args;
}

Add the above to your Toolset custom code section in Toolset -> Custom Code and activate it. You will need to change the 503724 to your view's id as well as the wwpcf-exam-date to the slug of your image field keeping the wpcf- prefix.

Problem:
I have created a nested Taxonomy view showing the Child Taxonomy Terms(nested child view) within a Parent Taxonomy Term (parent view) with the help of this guide https://toolset.com/documentation/user-guides/views/using-a-child-view-in-a-taxonomy-view-layout/#taxonomy-view-within-taxonomy-view

Everything is fine but I want to display specific Parent views set by specific parent term ID or anything convenient in this regard so that I can put them in page builder to generate views.

Solution:
We can pass a list of IDs, separated by comma(,) to the view if we configure a filter like shown on this screenshot http://prntscr.com/v12ke1
Then we can include the view like this:

[wpv-view name="my-taxonomy-view" terms="15"]
 
OR
 
[wpv-view name="my-taxonomy-view" terms="15, 27, 98"]
