只顯示頂級類別在wordpress中meta-by-line cubell主題

Question

我使用的是以下代碼的主題，以顯示旁邊的類別。我想知道是否有辦法只顯示第一個類別，而不是所有與該文章相關的類別。我的編碼技能並沒有擴展到這麼遠！

在此先感謝您的幫助。

    function cb_byline($cb_cat = true, $cb_post_id = NULL, $cb_short_comment_line = false, $cb_posts_on = false, $cb_post_views_off = false) { 

     if ($cb_post_id == NULL) { 
      global $post;
