php - laravel 使用用户函数验证

Question

Blade .php

......
<tr>
  <td>{{ Form::label('cameraMac', 'Mac: ') }}</td>
  <td>{{ Form::text('cameraMac')}}</td>
</tr>
......

Controller .php

$data = Input::all();
function transform($cameraMac) {
  return strtoupper($cameraMac);
}

//validation here

$user = User::find($data['user_id']);

if($data["cameraMac"])
{
    $user->camera_id = transform($data["cameraMac"]);
    Cloud_camera::create(['id' => transform($data["cameraMac"]), 'user_id' => $user->id]);
}

$user->save();

我需要将 cameraMac 转换为主键以存储在数据库中。如何在验证规则 'nullable|unique:cloud_cameras,id|size:6' 中使用函数 transform()。也就是说，在验证过程中如何调用这个函数。

Answer 1

如果您需要以某种方式转换输入数据，您可以使用merge 方法:

Input::merge(['cameraMac' => transform(Input::get('cameraMac')]);
$this->validate(Input::getFacadeRoot(), [
    'cameraMac' => 'nullable|unique:cloud_cameras,id|size:6'
]);

作为个人偏好，我会在 Controller 方法中输入提示 Illuminate\Http\Request $request 然后

$request->merge(['cameraMac' => transform($request->cameraMac)]);
$this->validate($request, ['cameraMac' => 'nullable|unique:cloud_cameras,id|size:6'
]);
