让wmd:type调用栏目内容content的方法

$row = $dsql->GetOne("SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
                          FROM `wmd_arctype` WHERE id='$typeid' ");

$row = $dsql->GetOne("SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,content,siteurl,sitepath 
                          FROM `wmd_arctype` WHERE id='$typeid' ");
