   How can I add the name of the custom taxonomy term that a post belongs to on single.php into the body_class?

   I've been able to add it when on taxonomy.php but when I click through from this page to a single post, the taxonomy term class disappears from the body tag.

   I've checked that when on single.php the taxonomy term is recognised by adding this code in:
   

   <?php
   if( false != get_the_term_list( $post->ID, 'bespoke_type' ) ) {
        echo 'The taxonomy is:' . get_the_term_list($post->ID,'bespoke_type', ' ', ' ', '' );
   }
   ?>

   and this does indeed return the name of my taxonomy term (with a link to its taxonomy.php).

   Any help would be marvelous.

   Having more of a rummage, it seems that get_the_terms is a better function to use.

   How do I code it so that I can add the output of get_the_terms to my body_class() ?

   I found this:
   http://davebonds.com/blog/add-css-classes-for-custom-taxonomies-in-wordpress.html
   the last example is really close. If i change it slightly from post_class to body_class though i get errors.

   My code:
   

   add_filter( 'body_class', 'mysite_body_class', 10, 3 );
   if( !function_exists( 'mysite_body_class' ) ) {
       function mysite_body_class( $classes, $class, $ID ) {
           $taxonomy = 'name_of_your_taxonomy_here';
           $terms = get_the_terms( (int) $ID, $taxonomy );
           if( !empty( $terms ) ) {
               foreach( (array) $terms as $order => $term ) {
                   if( !in_array( $term->slug, $classes ) ) {
                       $classes[] = $term->slug;
                   }}}
           return $classes;
       }}

   The errors i get:

   Warning: Missing argument 3 for mysite_body_class()

   Anyone?? I'm so close...

   ok after a few days research ... I found this which works:
   http://wordpress.org/support/topic/style-taxonomy-posts?replies=3#post-2815963

   and also this (NB: change the taxonomy name to your one)
   

   // another go
   function wpprogrammer_custom_taxonomy_in_body_class( $classes ){
     if( is_singular() )
     {
       $custom_terms = get_the_terms(0, 'your-taxonomy-name');
       if ($custom_terms) {
         foreach ($custom_terms as $custom_term) {
           $classes[] = 'custom_tax_' . $custom_term->slug;
         }
       }
     }
     return $classes;
   }
   
   add_filter( 'body_class', 'wpprogrammer_custom_taxonomy_in_body_class' );

   Hope this is useful for someone
