那个代码换一下位置就可以了:
public function index()
{
//分类信息显示
$cateId=Request::param('cate_id');
//如果存在这个分类
if (isset($cateId)){
$res=ArtCate::get($cateId);
$this->view->assign('cateName',$res->name);
$artList=Db::name('zh_article')
->where('status',1)
->where('cate_id',$cateId)
->order('create_time','desc')->paginate(3);
$this->view->assign('artList',$artList);
}
else{
$artList=Db::name('zh_article')
->where('status',1)
->order('create_time','desc')->paginate(3);
$this->view->assign('cateName','全部文章');
}
$this->view->assign('artList',$artList);
return $this->fetch();
}

抱歉,应该是这样的:
if (isset($cateId))
#{
$artList=Db::table('zh_article')
->where ('status',1)
->where('cate_id',$cateId)
->order('create_time','desc')->paginate(3);
##}
$artList=Db::table('zh_article')
->where('status',1)
->where('cate_id', $cateId)
->order('create_time','desc')->paginate(3);
$this->view->assign('artList' ,$artList);
return $this->fetch();
