How to show only parent terms with get_the_term_list() shortcode - Wordpress Solution
Hi, I have this shortcode: 
function post_taxonomy_sc( $atts ) {
    $defaults = [
        'post_id' => get_the_id(),
		'taxonomy' => 'category',
        'before' => '',
        'sep' => ', ',
        'after' => '',
        'linked' => 'yes',
    ];

	$atts = shortcode_atts($defaults, $atts, 'post_taxonomy');

    if($atts['linked'] == 'yes'){
        $terms = get_the_term_list($atts['post_id'], $atts['taxonomy'], $atts['before'], $atts['sep'], $atts['after']);
        } 
    else {
        $terms = strip_tags(get_the_term_list($atts['post_id'], $atts['taxonomy'], $atts['before'], $atts['sep'], $atts['after'] ));
        }
    return "<span class=\"post-taxonomy-terms-sc\">" . $terms . "</span>";
}
add_shortcode( 'post_taxonomy', 'post_taxonomy_sc' );
When used, I can output a list of taxonomy terms based on a specific taxonomy for a specific post. As an example, I have a custom taxonomy called "Payout Options" with terms like "PayPal", "Payoneer", and "Gift cards". The shortcode would output something like this: "PayPal, Gift cards, Payoneer" (if those terms were selected for a post) This is where I'm having problems: The "Gift cards" term has child terms like "Amazon gift cards" and "Walmart gift cards" If the Gift cards term exists on a post along with "Amazon gift cards" and "Walmart gift cards", I want the shortcode to only output "Gift cards" ignoring the child terms. Is this possible? How would I do this? I would also settle for being able to output like this: "Gift cards (Amazon gift cards, Walmart gift cards), PayPal, Payoneer" because at the moment it outputs in alphabetical order and looks very weird. Hope this makes sense! Thank you.

Yry using the get_terms () function instead and use the list of terms as you wish. this is the documentation: https://developer.wordpress.org/reference/functions/get_terms/ If parent => 0 is passed, only top-level terms will be returned 

$terms = get_terms( array( 
    'taxonomy' => 'tax_name',
    'parent'   => 0
) );

You can use the get_terms function in WordPress with "parent"=>0 attribute, it will return the term object then you can manipulate it with a for loop to get the desired output. https://developer.wordpress.org/reference/functions/get_terms/ 


$terms= get_terms( array(
    		'taxonomy' => 'category',
    		'parent' => 0
			) );
Term Object that is returned will look something like this WP_Term Object ( [term_id] => [name] => [slug] => [term_group] => [term_taxonomy_id] => [taxonomy] => [description] => [parent] => [count] => [filter] => ) 

foreach ($terms as $term) {
					echo '<a rel="nofollow" href="'.get_category_link($term->ID).'">'.$term->name.'</a>, ';
				}
You can loop through the terms to get the desired output as you desire Thanks Monit
