DEDE为CHANNEL 标签开启 description”栏目描述”属性

channel 这个标签没有description属性你需要自己把这个属性开启。到你的程序目录 include\taglib 找到 channel.lib.php 修改一下文件（78行~94行），如果你想查找所有top最顶层的栏目描述的话修改，以下代码top/son/self都开启了栏目描述。（红色代码）

if($type=='top')

    {
        $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
          From `#@__arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line ";
    }
    else if($type=='son')
    {
        if($typeid==0) return '';
        $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
          From `#@__arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit 0, $line ";
    }
    else if($type=='self')
    {
        if($reid==0) return '';
        $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
            FROM `#@__arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";
    }
