如何在Laravel 5中访问集合的单一值属性

Question

我的控制器中有一个通过控制器传递的变量：name是$ others

当我做一个foreach并打印时

 @foreach($others as $other)
   {{ $other }}
 @endforeach

输出为：

[{"employeeID":"9125123981003","email":"admin@gaincafe.com","fullName":"Pranshu Jain"}]     [{"employeeID":"45755757577","email":"yoyo@pranshu.com","fullName":"Pranshu Jain"}]

我要从中访问单个属性？ 他们是收藏吗？

我尝试过这样

  @foreach($others as $other)
    {{ $other->email }}
  @endforeach

这是我如何获得这个$others ：

 public function show($id)
   {
    $this->data['leave_application'] = Attendance::find($id);
    $date_applied_on =  $this->data['leave_application']->date;
    $emp_id =  $this->data['leave_application']->employeeID;
    $other_on_leave = Attendance::where('date', '=', $date_applied_on)->get();
    $employees_on_leave = [];

    foreach($other_on_leave as $others) {
        if($emp_id != $others->employeeID) {
           $emptyarray = Employee::where('employeeID', '=', $others->employeeID)->get(array('employeeID','email','fullName'));

           $employees_on_leave[] = $emptyarray;
        }
    }


    $this->data['others'] = $employees_on_leave;
    return view('admin.leave_applications.show', $this->data);
}

但这行不通。 请帮助和指导一点。 我熟悉数组和对象。 我曾经和他们做得很好。 但这似乎并不复杂。

如果我做dd（$ others）然后我得到

                array:2 [▼
              0 => Collection {#344 ▼
                #items: array:1 [▼
                  0 => Employee {#345 ▼
                    #guarded: array:1 [▼
                      0 => "id"
                    ]
                    #hidden: array:1 [▼
                      0 => "password"
                    ]

                  }
                ]
              }
              1 => Collection {#346 ▼
                #items: array:1 [▼

                    +wasRecentlyCreated: false
                  }
                ]
              }
            ]

Answer 1

在这里尝试first()而不是get() ：

$emptyarray = Employee::where('employeeID', '=', $others->employeeID)->first(array('employeeID','email','fullName'));

如果您仍想使用get() ，请执行以下操作：

foreach($other_on_leave as $others) {
    if($emp_id != $others->employeeID) {
        $emptyarray = Employee::where('employeeID', '=', $others->employeeID)->get(array('employeeID','email','fullName'));

        foreach($emptyarray as $arr){
            $employees_on_leave[] = $arr;
        }
    }
}

并更改此行，以便视图可以理解要遍历的内容：

return view('admin.leave_applications.show', ['others' => $this->data['others', 'leave_application' => $this->data['leave_application']]);

让我知道它是否有效。
