List of taxonomy children

Hi,

I have a pod with trips for an travel agency with an added taxonomy “countries”. The taxonomy is built of parents (continents) and then all the respective countries as children of the continents. Each trip is labelled by the contintent and all the countries that the trip is going to.

When I call that taxonomy in a template, I can call
```
{@countries}
```
which will give a list of all contintents AND countries, like: “Europe, France and Germany”.

I can call
```
{@countries.parent.name}
```
which will give just “Europe”.

How can I get an output of just “France and Germany” (or better, “France Germany” without the “and”), so I can get add a globe icon before the continent and flag icons before the countries ?

Thanks,
Astrid

Add the below shortcode, [countries] by adding to to wp-content/plugins/countries-shortcode/countries-shortcode.php or using Code Snippets:

<?php
/**
 * Plugin Name: Countries Shortcode
 */
add_shortcode(
	'countries',
	function( $atts, $content, $tag ) {
		return (string) implode(
			' ',
			(array) wp_get_object_terms(
				get_the_ID(),
				'countries',
				[
					'orderby' => 'name',
					'childless' => true,
					'fields' => 'names',
				]
			) 
		);
	}
);

For adding flags next to the country names, it might look like this if you have a folder of images, or the image value could be retrieved from a field:

<?php
/**
 * Plugin Name: Countries Shortcode
 */
add_shortcode(
	'countries',
	function( $atts, $content, $tag ) {
		ob_start();
		$country_names = (array) wp_get_object_terms(
			get_the_ID(),
			'country',
			[
				'orderby' => 'name',
				'childless' => true,
				'fields' => 'names',
			]
		);
		foreach( $country_names as $country_name ) {
			printf(
				'<span><img src="/folder/with/flags/%s.png" />%s</span> ',
				esc_url( sanitize_key( $country_name ) ),
				esc_html( $country_name )
			);
		}
		return trim( ob_get_clean() );
	}
);
