	    if(!$info){
			$this->error('刪除失敗');
		}else{
			$sheet = M("$dataSheet");//刪除欄目同步刪除對應的文章
			$map['sort'] = "$typename";
			$sheet->where($map)->delete();
			$this->success('刪除成功',U("Index/arctype?channelId=$channelId"));

常常使用一下程式碼，刪除文章可以用，但是不知為什麼刪除欄目時忽然不能用了

$this->success('刪除成功',"arctype/channelId/$channelId");

使用U函式生成地址後可以用了

$this->success('刪除成功',U("Index/arctype?channelId=$channelId"));
