blade.php
......
<tr>
<td>{{ Form::label('cameraMac', 'Mac: ') }}</td>
<td>{{ Form::text('cameraMac')}}</td>
</tr>
......
Controller.php这样
$data = Input::all();
function transform($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db中。如何在验证规则transform()
中使用函数'nullable|unique:cloud_cameras,id|size:6'
。这就是说,如何在验证过程中调用此函数。

如果您需要以某种方式转换输入数据,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,我会在控制器方法中键入-hint Illuminate\Http\Request $request
然后
$request->merge(['cameraMac' => transform($request->cameraMac)]);
$this->validate($request, ['cameraMac' => 'nullable|unique:cloud_cameras,id|size:6'
]);

我考虑PH-Tree。
中间件将执行转换并在击中控制器之前将结果合并回请求。
class TransformId {
public function handle(Request $request, Closure $next) {
// shout out to @alepeino
$request->merge(['cameraMac' => transform($request->cameraMac)]);
return $next($request);
}
}
答案 2 :(得分:1)
您是否真的想要将字段cameraMac
作为(或多或少)主键可以为空?
您还应使用int
验证来使用size
验证
unique
validation的第三个参数是except
,它将忽略给定的ID。
您在控制器中的验证可能如下所示
$except_id = $request->input('cameraMac', null);
$this->validate($request, [
'cameraMac' => 'nullable|unique:cloud_cameras,id,'.$except_id.'|int|size:6'
]);
One example如何在视图中显示您的验证错误
@if (count($errors) > 0)
<div class="alert alert-danger">
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif

现在我首先转换输入数据,然后以下面的方式验证它。
但我正在寻找在验证中调用此功能的方法。
$data = Input::all();
$data['cameraMac'] = transform($data['cameraMac']);
$rules = array(
'id' => 'required|unique:cloud_printers,id|size:6',
'cameraMac' => 'unique:cloud_cameras,id|size:6',
);
$validator = Validator::make($data, $rules);
if ($validator->fails())
return Redirect::back()->withInput()->withErrors($validator);

您可以定义custom validation rule:
char input;
displayWellDoneMenu();
scanf("%c", &input);
while (input != '1' || input != '2')
{
printf("You must select 1 or 2!\n");
displayWellDoneMenu();
scanf("%c", &input);
rewind(stdin);
system("cls");
}
switch (input)
{
case'1':
additionIntermediate();
break;
case '2':
main();
break;
}
然后像往常一样在请求中使用新规则:
Validator::extend('transformUpper', function ($attribute, $value, $parameters, $validator) {
return strtoupper($value);
});
