destoon7.0/8.0根据模块目录输出地图sitemap.xml

解决问题：解决网站内容比较多，原来多模块的数据用单个sitemaps.xml地图来调用完全不够用，所以就写了模块地图单独输出，这样对seo有帮助，提高蜘蛛抓取。
开始解决办法：找到目录下面:/module/extend/sitemaps.htm.php 文件
把原来的代码换成以下：

<?php
defined('IN_DESTOON') or exit('Access Denied');
if(!$MOD['sitemaps']) {
    file_del(DT_ROOT.'/sitemaps.xml');
    return false;
}
$today = timetodate($DT_TIME, 3);
$mods = explode(',', $MOD['sitemaps_module']);
$nums = intval($MOD['sitemaps_items']/count($mods));
$data = '<?xml version="1.0" encoding="UTF-8"?>';
$data .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';
$data .= '<url>';

?>

这样保存，然后进入后台，地图生成即可。
这样访问目录：规则为：域名/模块/sitemaps.xml
老地图：http://www.liuqiuyi.com/sitemaps.xml
修改后地图：http://www.liuqiuyi.com/liuxue/sitemaps.xml
