I'm templating a single.php and I want to display something like 'Destination: Paris' or 'Destinations: Paris, London'. So I'd like to check if the taxonomy 'Destination' has more than one item in order to output 'Destination' if tax has only one item and 'Destinations' if tax has more than one item. Thanks for any help you guys might provide!
And if you want to check if current post has more than one term in given taxonomy (it's not very clear in your question and this version makes much more sense for me...), then function
get_the_terms will come handy:
$terms = get_the_terms( $post, $taxonomy ); echo ( count($terms) > 1 ) ? 'Destinations' : 'Destination';
