要用 shortcode 顯示文章分類名稱，可以在 function.php 加入以下程式碼：
function shortcode_post_category($atts=array()) {
// get taxonomy by post type
$tax = get_object_taxonomies(get_post_type());
// get the categories of the taxonomy
$cats = get_the_terms($post->ID, $tax[0]);
$result = '';
foreach ($cats as $cat) {
$result = $cat->name;
return $result;
}
return $result;
}
add_shortcode('post_category', 'shortcode_post_category');
