模板调用    [field:sonchannel0] [/field:sonchannel0] 这个是用来取子栏目用得（使用[sonchannel+数字] 作为标签名是为了防止嵌套的时候无法正确解析标签）

                            <li><a href="dede58.com/[field:typelink/]">===[field:typename/]</a></li>
                    [field:sonchannel0]
    //And id<>'$typeid'
    extract($ctag->CAttribute->Items, EXTR_SKIP);
    }
        //检查是否有子栏目，并返回rel提示（用于二级菜单）

一、修改文件：\include\taglib目录下的channel.lib.php，请将以下代码全部复制替换上述文件

这个的作用就是当你的栏目有很多子栏目 无限分级的时候方便你取子栏目的

    $totalRow = $dsql->GetTotalRow();
                    $likeType .= $dtp2->GetResult();
            $likeType .= "    </dl>\r\n";
        $reid=0;
                    if($currentstyle!='')
                                $dtp2->Assign($tagid,lib_channel_son($ctag,$row['id'],$dsql2));
                {
    }

二、在模板调用
    $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
                        if(isset($row[$ctag->GetName()]))

                        elseif (preg_match('/^sonchannel[0-9]*$/',$ctag->GetName()))
    $dtp2 = new DedeTagParse();
                }else
    if(ereg(':rel', $innertext)) $needRel = true;
?>

    if(empty($sql)) return '';
    $GLOBALS['autoindex'] = 0;
    $reid = 0;
    return $likeType;
    //And id<>'$typeid'
                    }
    $dsql2->FreeResult();
    $dsql->Execute();
            if($col>1) $likeType .= "<dd>\r\n";
    $dsql->Execute();
    {
    }else{
    }

}
        $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
