    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.

    Example for check if a post of cpt have a specific term of a custom taxonomy.
    In this example we check if the post have a term ‘action’ and in this case asign one css class to a variable that we use later on html.
    CPT: “hook”
    Taxonomy: “hook-type”
    Taxonomy terms: “action” and “filter”.
    Note that in this example, this code is inside a cpt archive file “archive-hook.php”.

    $hook_css_class = '';
if (has_term( 'action', 'hook-type' )) {
  $hook_css_class = "is-action-hook";
} else {
  $hook_css_class = "is-filter-hook";
};
