如何在 Laravel 控制器函数中将数组格式化为特定格式？

Question

我目前正在创建Laravel Vue水疗中心，只是想知道如何使用这些名称ID的名称使用相同的结构。这是名称ID的JSON：

[
  [
    1,
    5
  ],
  [
    1,
    3
  ]
]

这是我的getDesignations employscontroller.php：

    public function getDesignations($id) {
        $employee_designation_ids = Employees::find($id)->pluck('designation_id')->toArray();
        $designation_name = [];
        foreach ($employee_designation_ids as $employee_designation_id) {
            $designation = Designations::where('id', '=', $employee_designation_id); 
            //$designation_name[] =  $designation;
        }

        return $employee_designation_ids;
    }

Answer 1

如果您特别想要这种格式，您可以这样做（我有很多猜测，因为您没有共享您的表结构）

public function getDesignations($id) {
    $employee_designation_ids = Employees::find($id)->designation_id;
    return [[$id, $employee_designation_ids]];
}

但是为什么您要为单行结果返回双表。

感谢您的帮助！我已经在控制器中使用了此方法来解决它：

public function getDesignations(Request $request, $id) {
        $employee_designation_ids = Employees::where('id', $id)->pluck('designation_id');
        return Designations::whereIn('id', $employee_designation_ids[0])->pluck('name');
    }
