Can I use a Custom Meta Value inside of ‘get_the_terms’?

Seemed have found a solution via customizing a code snippet from here:
http://wordpress.org/support/topic/get_the_terms-using-array-of-taxonomies

$taxonomy = get_the_terms($post->id, get_post_meta($post->ID,'metafield-taxonomy-name',TRUE) );

$terms = get_the_terms($post->id, $taxonomy );
  • $taxonomy must be placed outside of post loop.

Thanks!
