Question

我试图找到这个问题的答案，但没有任何帮助。我有一个辅助功能

function a($id, $b = false)
{
$general = Feedbacks::join("bidders","bidders.id","=","feedbacks.bid_id")
    ->join("projects","bidders.project_id","=","projects.id")

    ->where([

        "bidders.bidder_id" =>  $id,

        "bidders.status"    =>  2,

        "feedbacks.active"  =>  1,

        "bidders.active"    =>  1,

        "projects.active"   =>  config("constant.project_done")
    ])

    ->orderBy("feedbacks.created_at","DESC");

    print_r($general);die;

}

对于Controller端，我正在获取$ id并将其传递给此函数。

$id      =  Feedbacks::where('active',1)->get(['bid_id']);

    $rate    =  "";

    foreach ($id as $val) {

      $rate = $val->bid_id;

    }

    $re = a($rate,true);

因此，如果我打印$ id的值，它将返回正确的值，但是当我尝试打印$general时，它将引发此标题中提到的错误。我不知道这里有什么问题。谁能指导我？
