fastadmin - 自定义selectPage接口

1.结构  list+total

 return ['list' => $list, 'total' => $total];

list需要用limit分页，页码字段是pageNumber

2.赋值

如果获取到keyValue的值的话就根据值来做相应的where条件

在编辑页面初始化页面的时候，第一次会将关联id作为keyValue传到后台，点击选择框之后的异步调用则不会传keyValue

3.示例

    public function query()
    {
        $account = Admin::get($this->auth->id);
        $page = $this->request->request('pageNumber')?:1;
        $param = input();
        $id = (isset($param['keyValue'])&&$param['keyValue'])>0?$param['keyValue']:0;
        $zhi = 10;
        $tiao = ($page-1)*$zhi;
        $where = ['status' => 'normal'];
        if($account['position_ids']!="all"&&$account['position_ids']!=""){
            $where['position_id'] = ["IN",$account['position_ids']];
        }
        if($id>0){
            $where['id'] = $id;
        }
        if($param['username']!="") $where['username'] = ['like',"%{$param['username']}%"];
        $list    = Db::name("user")->where($where)->field("id,username,position_id")->limit($tiao,$zhi)->select();
        $total    = Db::name("user")->where($where)->field("id,username,position_id")->count();
        return ['list' => $list, 'total' => $total];
    }
