Sort posts by custom taxonomy name

Question

Is it possible to sort posts (custom post type) by category / taxonomy (name, desc)?

For example my categories would be

• Season 2012
  • some post
  • some post
  • some post
• Season 2011
  • some post
  • some post
  • some post
• Season 2010
• etc..

Answer 1

One solution would be-

$terms = get_terms('taxonomy-name');
foreach($terms as $term) {
    $posts = get_posts(array(
            'post_type' => 'custom_post_type_name',
            'tax_query' => array(
                array(
                    'taxonomy' => 'taxonomy-name',
                    'field' => 'slug',
                    'terms' => $term->slug
                )
            ),
            'numberposts' => -1
        ));
    foreach($posts as $post) {
        // do what you want to do with the posts here
    }
}

Answer 2

Alternative loop, where tax = category and custom post type = "results"

$args = array( 'taxonomy' => 'category' );
$terms = get_terms( 'category', $args);

//START FOR EACH LOOP
foreach ($terms as $term) {

            $post_type = 'results';
            $tax = 'category';
            $tax_terms = get_terms( $tax );
            if ($tax_terms) {
                foreach ($tax_terms  as $tax_term) {
                $args = array(
                    'post_type' => $post_type,
                    "$tax" => $tax_term->slug,
                    'post_status' => 'publish',
                    'posts_per_page' => -1,
                    'caller_get_posts'=> 1
                );



                $my_query = null;
                $my_query = new WP_Query($args);

                if( $my_query->have_posts() ) : ?>

                        // WHILE
                        <?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>

                        // Do stuff

                        <?php endwhile; ?>
                        // END WHILE


                <?php else : ?>
    <?php endif; wp_reset_query(); ?>

}
// END FOR EACH LOOP
