您好，这是我使用的一个示例：

<?php while ( have_posts() ) : the_post(); 

  $category = get_the_terms( $id, \'event_category\' );
  //get First Category
  $firstCategory = $category[0];
  //get category link
    $category_link = get_category_link($firstCategory->term_id);
    //echo category name
    echo $firstCategory->name;

 endwhile;
?>   

Try this one please:

$terms = get_the_terms(); $term = reset($terms);
