Question

我使用下面代码的主题来显示旁边的类别。我想知道是否有办法只显示第一个类别，而不是所有与帖子相关联的类别。我的编码技能并没有延伸到这么远！

提前感谢您的帮助。

R上。萨姆

if ( ! function_exists( 'cb_byline' ) ) {
    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;
            $cb_post_id = $post->ID;
        }

        $cb_meta_onoff = ot_get_option( 'cb_meta_onoff', 'on' );
