laravel 中条件查询 function模式

当需要条件查找时，可以使用下面的注入方法：

//我要预约 yudoc_name yudoc_keshi yudoc_jibing yudoc_hospital  这是需要帅选的条件
    public function userYuYueDoc(Request $r) {
        $data = $r->all();
        //获取医生
        $res = \DB::table('dxjk_yudoc')
            ->where('yudoc_status',2)
            ->where(function($query)use($data){
                if($data['yudoc_name'] !== ''){//这一步成立才会查询
                    $query->where('yudoc_name','like', '%'.$data['yudoc_name'].'%');
                }
            })
            ->where(function($query)use($data){
                if($data['yudoc_jibing'] !== ''){
                    //按疾病查找
                    $jibing_res = \DB::table('dxjk_yudoc')
                        ->select('yudoc_id','yudoc_jibing')
                        ->get();
                    $doc_id = array();
