[Resolved] Display different parts of Custom Taxonomy separately

I would like to be able to display different terms of a Custom Taxonomy separately.

At the moment I have a taxonomy called Locations. I have the terms set out like this: Country, City, Area. So in my example I have: United Kingdom, London, Islington.

I can display these on the Front End using a View. I am currently using the below to do this.

[wpv-taxonomy-link]
 <br>
[types termmeta='flag' title='%%TITLE%%' alt='%%ALT%%' size='full'][/types]

You can see from my View Output screenshot that all the taxonomy terms display together.

Is there any way I can display each term separately? For example, display the Area and City together and then display the Country separate somewhere else?

Hi Ben,

Thank you for contacting us and I'll be happy to assist.

There is no built-in shortcode available to show taxonomy terms, separated based on the hierarchy level.

To achieve this, you can register a custom shortcode, that gets all the terms attached to a post and then only show them, based on the provided "level" attribute.

The following code can be added to the active theme's "functions.php" file:

add_shortcode('get_terms_by_level', 'get_terms_by_level_func');
function get_terms_by_level_func($atts) {
     
	$taxonomy = $atts['taxonomy'];
	$postid = $atts['id'];
	$level = $atts['level'];

	if( !(isset($level)) || (empty($level)) ) {
		$level = 1;
	}

	$terms = get_the_terms( $postid, $taxonomy);

	if ( $terms && ! is_wp_error( $terms ) ) {

		foreach ($terms as $term) {

			if($term->parent == 0) {
				$results['1'] = array('id' => $term->term_id, 'name' => $term->name, 'slug' => $term->slug, 'parent' => $term->parent);		
			} else {
				$tmpresults[] = array('id' => $term->term_id, 'name' => $term->name, 'slug' => $term->slug, 'parent' => $term->parent);
			}

		}

		foreach ($tmpresults as $result) {
			if($result['parent'] == $results['1']['id']) {

				$results['2'] = array('id' => $result['id'], 'name' => $result['name'], 'slug' => $result['slug'], 'parent' => $result['parent']);
				
			}
			else {
				$results['3'] = array('id' => $result['id'], 'name' => $result['name'], 'slug' => $result['slug'], 'parent' => $result['parent']);
			}
		}

		return '<a href="' . esc_url( get_term_link( $results[$level]['id'], $taxonomy) ) . '">' . $results[$level]['name'] . '</a>';

	}
   
}

After that, in your view, you can use this new shortcode to show terms at different levels like this:

// get country level term with level 1
[get_terms_by_level id="[wpv-post-id]" taxonomy="category" level="1"]

// get city level term with level 2
[get_terms_by_level id="[wpv-post-id]" taxonomy="category" level="2"]

// get area level term with level 3
[get_terms_by_level id="[wpv-post-id]" taxonomy="category" level="3"]

Note: Please replace "category" with the actual slug of your custom taxonomy.

I hope this helps and please let me know if you have any questions around this approach.

Waqar
