If you want to access the taxonomy items on a particular post:

$terms = get_the_terms( $post->ID, 'subjects' );
foreach ( $terms as $term ) {
echo str_replace(' ', '', $term->slug);
}

If you want to print all the taxonomies for a particular custom post:

<?php
$terms = get_terms( 'subjects' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
foreach ( $terms as $term ) {
echo '<a id="' . $term->slug . '">' . $term->name . '</a>';
}
}
?>

Perhaps you want to change the order in which a custom taxonomy spits out its elements? This plugin will do in a pinch. Install it, and you’ll get a new item in your left nav: TERM ORDER. Inside the nav items, you can choose which taxonomy you want to reorder. Just make sure you select the radio button at the bottom of the page to have the sort be your new order.
