您不需要對(duì)單個(gè)記錄應(yīng)用循環(huán)，因?yàn)槟梢钥吹剿菃蝹€(gè)記錄。
<div class="card" >
<div class="card-body ">
<div class="shipment-number">
<span class="title" style="display: block; font-size: 25px!important;">{{$shipment->tracking_code }}</span>
</div><!-- Track_Num -->
</div>

<div id="shipper-info" class="row" >
<div class="col-md-6 detail-section">

<div class="shipper details">

您的調(diào)用->first()將返回一批貨件而不是一批貨件，您可以使用->get()或->paginate()獲取模型的集合，然后在您的視圖中迭代它們。

獲取數(shù)據(jù)時(shí)刪除->first()，->get() or ->paginate(x)改為使用，這樣您就可以獲得集合。
在刀片文件中，foreach循環(huán)使用相同的變量作為集合和單個(gè)數(shù)據(jù)
@foreach($shipment as $shipment)
我建議您使用$shipments集合作為變量，并使用 $shipment 作為實(shí)例。
x 只是一個(gè)數(shù)字
