地址的Laravel验证规则

问题描述：

In my project forms I request users to input addresses. Sometimes a single form can have 2 addresses. An address is always 3 fields (city, street and house number).

To validate I use an external service that returns either gps coordinates or an error, in which case I manually add an error to the validator. I even wrote a helper function so in my controllers it looks like this:

$this->validateAddress(
    $v,
    $request->input('firstaddr.city'),
    $request->input('firstaddr.street'),
    $request->input('firstaddr.house')
);
$this->validateAddress(
    $v,
    $request->input('secondaddr.city'),
    $request->input('secondaddr.street'),
    $request->input('secondaddr.house')
);

However this solution seems very hacky and repetitive, what I want is just to pass a rule to the validator, that will only receive a prefix, like "firstaddr" or "secondaddr". Is it possible to do it?

在我的项目表单中，我请求用户输入地址。有时单个表单可以有2个地址。地址总是3个字段（城市，街道和门牌号）。 p>

要验证我使用的是返回gps坐标或错误的外部服务，在这种情况下我手动添加错误到验证器。我甚至写了一个辅助函数，所以在我的控制器中看起来像这样： p>

  $ this-＆gt; validateAddress（
 $ v，
 $ request-＆gt; input（  'firstaddr.city'），
 $ request-＆gt; input（'firstaddr.street'），
 $ request-＆gt; input（'firstaddr.house'）
）; 
 $ this-＆gt; validateAddress  （
 $ v，
 $ request-＆gt; input（'secondaddr.city'），
 $ request-＆gt; input（'secondaddr.street'），
 $ request-＆gt; input（'secondaddr。  house'）
）; 
  code>  pre> 
 
 然而，这个解决方案似乎非常hacky和重复，我想要的只是将规则传递给验证器，只会收到 一个前缀，如“firstaddr”或“secondaddr”。 有可能吗？ p> 
  div>

答

Since Laravel 5.5 you can define custom validation rules.

In your controller it would look something like

$request->validate([
    'firstaddr' => [new Address],
    'secondaddr => [new Address]
]);

And you could combine that with a form request validation so that the validation logic happens before the execution enters the controller.
