使用

functions.php

function get_current_tag_id() {
    $current_tag = single_tag_title(\'\', false);//获得当前TAG标签名称
    $tags = get_tags();//获得所有TAG标签信息的数组
    foreach($tags as $tag) {
        if($tag->name == $current_tag) return $tag->term_id; //获得当前TAG标签ID，其中term_id就是tag ID
    }
}

tag页面

<?php $str = get_term_meta(get_current_tag_id());echo $str[\'tag-keywords\'][0]?>
<?php $str = get_term_meta(get_current_tag_id());echo $str[\'tag-description\'][0]?>
