修改文件
/application/home/controller/Tags.php
找到如下代码（大概在130行左右）：
'litpic'   => !empty($tagindexInfo['litpic']) ? handle_subdir_pic($tagindexInfo['litpic']) : $tagindexInfo['litpic'],
在此代码下方添加代码
'tagcount'   => !empty($tagindexInfo['count']) ? $tagindexInfo['count'] : $tagindexInfo['count'],
'tagtotal'   => !empty($tagindexInfo['total']) ? $tagindexInfo['total'] : $tagindexInfo['total'],
模板调取标签
{$eyou.field.tagtotal}
{$eyou.field.tagcount}
