有时候想在网页中向访客展示emlog博客的文章数量、评论数量、运行时间等信息，但emlog后台侧边栏没有提供相关的模块，因此需要博主自主添加博客统计信息代码。下面是博客吧整理的emlog网站信息统计代码，已在emlog 5.3.x上测试可用。
方法一：官方缓存类统计代码。优点：加载速度快；缺点：可能信息更新不及时。
把以下代码添加到当前使用的主题模板文件中，如side.php文件：
readcache('sta'); /*必须添加*/ ?>
- 文章总数： 篇
- 评论总数： 条
- 闲言碎语：条
- 网站运行： 天
附：$sta_cache[‘参数’]中的参数可选如下：
lognum游客可见日志总数
draftnum草稿，也就是隐藏文件数量
comnum未隐藏的评论数量
comnum_all所有评论数量
hidecomnum被隐藏的评论数量
twnum微语数量
checknum未审核的文章数量
方法二：自编函数，通过sql语句查询相关数据。缺点：加载速度较缓存类慢；优点：实时显示
把下面的代码添加到主题的module.php文件中：
once_fetch_array("select count(*) as total from " . db_prefix . "blog where type = 'blog'");
return $data['total'];
}
//置顶文章数
function count_log_top(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "blog where top = 'y' or sortop = 'y' and type = 'blog'");
return $data['total'];
}
//隐藏文章数
function count_log_hide(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "blog where hide = 'y' and type = 'blog'");
return $data['total'];
}
//未审核文章数
function count_log_check(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "blog where checked = 'n' and type = 'blog'");
return $data['total'];
}
//加密文章数
function count_log_pass(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "blog where password !='' and type = 'blog'");
return $data['total'];
}
//统计页面总数
function count_page_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "blog where type = 'page'");
return $data['total'];
}
//统计评论总数
function count_com_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "comment");
return $data['total'];
}
//统计友链总数
function count_link_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "link");
return $data['total'];
}
//统计微语评论总数
function count_treply_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "reply");
return $data['total'];
}
//统计分类总数
function count_sort_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "sort");
return $data['total'];
}
//统计子分类数
function count_sort_mod(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "sort where pid != 0");
return $data['total'];
}
//统计标签总数
function count_tag_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "tag");
return $data['total'];
}
//统计微语总数
function count_tw_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "twitter");
return $data['total'];
}
//统计用户总数
function count_user_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "user");
return $data['total'];
}
//统计管理员总数
function count_user_admin(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "user where role = 'admin'");
return $data['total'];
}
//统计作者总数
function count_user_writer(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "user where role = 'writer'");
return $data['total'];
}
//统计附件总数
function count_att_all(){
$db = mysql::getinstance();
$data = $db->once_fetch_array("select count(*) as total from " . db_prefix . "attachment");
return $data['total'];
}
//最后发表文章时间
function last_post_log(){
$db = mysql::getinstance();
$sql = "select * from " . db_prefix . "blog where type='blog' order by date desc limit 0,1";
$res = $db->query($sql);
$row = $db->fetch_array($res);
$date = date('y-n-j h:i',$row['date']);
return $date;
};
?>
