php - Laravel 在 Web 服务器的 View 中显示数据

Question

它给我一个“尝试获取非对象的属性”的错误，你能帮我吗？它在我的离线服务器上正常工作，但是如果我将它上传到我的实时服务器上，它会出错

如果我 dd 我的 Controller 给出结果。

  #items: array:3 [▼
    0 => Branch {#297 ▼

          #visible: []
          #guarded: array:1 [▶]
          #rememberTokenName: "remember_token"
        }
      ]
      #touches: []
      +timestamps: true
      #hidden: []

      #fillable: []
      #guarded: array:1 [▶]
    }
    1 => Branch {#298 ▶}
    2 => Branch {#299 ▶}
  ]
}

但是当我让我的代码显示收银员的名字时。使用此代码

@foreach($dataBranch as $Branch)
<tr class="item{{$Branch->id}}">
<td> <a class="name">{{$Branch->branch_name}}</a> </td>
<td> <a class="name">{{$Branch->cashier->name}}</a> </td>
</tr>
@endforeach

它给我一个“尝试获取非对象的属性”的错误，你能帮我吗？它在我的离线服务器上正常工作，但是如果我将它上传到我的实时服务器上，它会出错

请帮忙

首先你需要调试foreach中的数据，然后尝试在条件下使用is_object() php函数来获取正确的数据字段。

您可以通过这种方式验证您的数据:

<?php 
//verify your data
foreach($dataBranch as $Branch) {

var_dump($Branch);

if(is_object($Branch)) {
  if(!empty($Branch->id)) {
   echo '$Branch->id';
  }
}}
exit;
?>
