//五表联查

$b=Db::table(‘user‘)

   ->join(‘userrole‘,‘user.uid =userrole.u_id‘)   ->join(‘role‘,‘userrole.r_id = role.rid‘)   ->join(‘roleaccese‘,‘role.rid =roleaccese.role_id‘)   ->join(‘accese‘,‘roleaccese.accese_id =accese.aid‘)   ->where("uname=‘$uname‘ and upass=‘$upass‘")   ->select();

//一级菜单

$arr=[];foreach ($b as $key => $v){    $arr[‘uname‘]=$v[‘uname‘];    $arr[‘upass‘]=$v[‘upass‘];    $arr["rname"]=$v[‘rname‘];    $arr[‘one_menu‘][]=[‘aname‘=>$v[‘aname‘],‘aurl‘=>$v[‘aurl‘],‘pid‘=>$v[‘pid‘],‘aid‘=>$v[‘aid‘]];}

//二级菜单

foreach($arr[‘one_menu‘] as $k =>$vv){     $res=Db::table("accese")->where("pid=".$vv[‘aid‘])->select();     $arr[‘one_menu‘][$k][‘two_menu‘]=$res;}

//表单展示

<div>    <ul>        {volist name="list.one_menu" id="v"}            <li><a href="{$v.aurl}">{$v.aname}</a></li>            <div>                <ul>                    {volist name="v.two_menu" id="vo"}                      <li><a href="{$vo.aurl}">{$vo.aname}</a></li>                    {/volist}                </ul>            </div>        {/volist}    </ul></div>
