Get all posts from custom taxonomy in Wordpress

Question

Is there a way to get all the posts from a taxonomy in Wordpress ?

In taxonomy.php, I have this code that gets the posts from the term related to the cu

While in the query loop for terms, you can collect all post references in an array and use that later in a new WP_Query.

$post__in = array(); 
while ( $terms_query->have_posts() ) : $terms_query->the_post();
    // Collect posts by reference for each term
    $post__in[] = get_the_ID();
endwhile;

...

$args = array();
$args['post__in'] = $post__in;
$args['orderby'] = 'post__in';
$other_query = new WP_Query( $args );
