我无法访问表格的id列

Question

我正在尝试访问我的某个表的id列，但我得到“未定义属性”错误但我可以访问其他列而没有任何问题，这是我的代码 在控制器中，我得到所有记录如下

        $employees=Employee::all();
    return View::make('admin.employee',compact('tittle','heading','employees'));

和我的观点

 @foreach($employees as $employee)
            <tr class="success">
                <td><a href="">{{$employee->first_name}}</a></td>
                <td>{{$employee->last_name}}</td>
                <td>{{$employee->phone}}</td>
                <td>{{$employee->salary}}</td>
                <td>{{$employee->created_at}}</td>
                <td><a href="{{URL::route('employee.view',array($employee->id))}}" class="btn btn-primary btn-xs">Edit</a></td>
                <td><a href="#" class="btn btn-success btn-xs">Resign</a></td>
                <td><a href="#" class="btn btn-warning btn-xs">View</a></td>
            </tr>
        @endforeach

如何从我的表中访问id列？ 当我print_r（$ employees）;

Answer 1

将 $ employees 对象提供给我们，使用

编辑问题

print_r($employees).

$ id 也有可能受到保护，在这种情况下使用。

$employee->getOriginal('id');
