I want to output all the terms in my custom taxonomy and at the same time add a class to any of these that are attached to the current post.
I'm doing this in a custom shortcode that displays on each single post page.
I've used get_terms() to show all the terms in the taxonomy but I can't work out how to check if each term is attached to the current post.
$terms = get_terms( array(
'taxonomy' => 'package',
'hide_empty' => false
) );
if (!empty($terms) && ! is_wp_error( $terms )) {
echo '<ul>';
foreach ($terms as $term) {
echo '<li>' . $term->name . '</li>';
}
echo '</ul>';
}

Reset to default 1how to check if each term is attached to the current post
You can do that using has_term() which defaults to checking on the current post in the main loop, hence you can omit the third parameter (the post ID).
So for example in your case:
$class = has_term( $term->term_id, $term->taxonomy ) ? 'active' : ''; // like this
//$class = has_term( $term->term_id, 'package' ) ? 'active' : ''; // or this
echo '<li class="' . $class . '">' . $term->name . '</li>';
taxonomy-my_tax.php? And what is the "current post"? Where does it come from? – Sally CJ Commented Sep 30, 2020 at 19:52
