Example
if( has_term( 'jazz', 'genre' ) ) { // do something }If you’re checking for the presence of any terms from a given taxonomy on a post, you can pass in an empty string as the first parameter.
Example
if( has_term('', 'genre') ){ // do something }This is useful if you want to conditionally display some markup that applies only if terms have been added to a post.
