[Resolved] Filter View by front-end shortcode (modify existing custom code)

I have a View and I want to filter it to show only top-level terms. Christian helped me set up Custom Code to do this for another Custom Taxonomy - I would like to use the same logic to apply the filter to the current Custom Taxonomy I'm working with ("video-category").

Here is my View: hidden link
The Custom Code Christian set up for me (for a different Custom Taxonomy, "my-classes") is the following:

<?php

toolset_snippet_security_check() or die( 'Direct access is not allowed' );

// Add shortcode to filter for n-level term or ID

function n_level_term_func($atts) {
  $a = shortcode_atts( array(
      'n' => '0',
      'format'=>'id',
  ), $atts );
  $current_taxonomy = get_queried_object()->taxonomy;
  $id = 0;
  $slug = '';
  if( $current_taxonomy == 'my-classes' ) {
    $ancestors = get_ancestors( get_queried_object()->term_id, $current_taxonomy );
    $count = count( $ancestors );
    $id = isset( $ancestors[ $count - $a['n'] ] ) ? $ancestors[ $count - $a['n']] : get_queried_object()->term_id;
    $term= get_term( $id, $current_taxonomy);
    $slug = isset($term->slug) ? $term->slug: $slug;
  }
  return $a['format']=='slug' ? $slug : $id;
}
add_shortcode("n-level-term", "n_level_term_func");

I have used this custom shortcode successfully to filter for top-level terms in other Views, for example [wpv-view name="class-parts-filtered-by-term" terms="[n-level-term n="1"]"].

The Custom Taxonomy I want to use in the View in this case is "video-category."

Here is how I am displaying the View on the page: [wpv-view name="video-categories-1" terms="[n-level-term n="1"]"]

(Here is the Test Page: hidden link)

Can you help me modify this Custom Code or make a new one so I can filter my Video Categories by top-level term? Thank you!

Hello,

I assume you are going to display all top level term of taxonomy "video-category", it does not need custom codes, you can create a taxonomy view:
- Query terms of taxonomy "video-category"
- Filter by:
Select taxonomy terms whose parent is None.
See screenshot top-term.JPG

It worked!! Thank you, Luo, I had no idea about this easy solution. You're the best!
