商业源码 织梦CMS四级子栏目的调用？
{dede:channel row='20' type ='son' typeid ='2' } 此处是底层标签 {/dede:channel}
row='20'表示调用20个栏目名称
type ='son'表示调用下级栏目
typeid ='2'表示父栏目id为2
关于底层标签，诸如栏目名称，链接等等就不再赘述了吧
1、首先，在dedecms网站后台进行登录，输入账号密码，进行网站后台的登录。
2、接着进入到织梦cms管理后台的首页，在左侧找到模块选项，找到友情链接，点击即可。
3、接着在右上角点击增加链接选项按钮，进入该填写页面。
4、然后将要进行添加的网址补充进去，网站名称就是网页上显示的名称关键词，填写完了点击提交。
5、提交完能看到右侧已经有我们刚才添加的友情链接，如图所示。
6、接着将网站主页更新一下，就可以在首页上看到刚才添加的友情链接了。
一、修改文件：\include\taglib目录下的channellibphp，请将以下代码全部复制替换上述文件
