267行：
if($ctag->GetAtt('cross')=='1')

if($ctag->GetAtt('cross')!='0')

 

282行：
if($arr['crossid']!='') $selquery = "SELECT id,topid FROM `dede_arctype` WHERE id IN('{$arr['crossid']}') AND id<>'{$typeid}' AND topid<>'{$typeid}'  ";
改成
if($arr['crossid']!='') $selquery = "SELECT id,topid FROM `dede_arctype` WHERE id IN({$arr['crossid']}) AND id<>'{$typeid}' AND topid<>'{$typeid}'  ";

 

OK，在栏目里面设置好要交叉的即可。
