Laravel 5 中的自定义验证器 [英] Custom validator in Laravel 5

问题描述

我正在将我的 Laravel 应用程序从 4 升级到 5.但是，我有一个无法开始工作的自定义验证器.

I am upgrading my Laravel application from 4 to 5. However, I have a custom validator that I cannot get to work.

在 L4 中，我创建了一个 validators.php 文件并使用 require app_path().'/validators.php' 将它包含在 global.php 中；.

In L4, I made a validators.php file and included it in global.php using require app_path().'/validators.php';.

我尝试在 L5 中做一些相同的事情.我在 app/Validators/Validators.php 中删除了一个验证器，并更新了我的 composer.json.

I tried doing somewhat the same in L5. I dropped a validator in app/Validators/Validators.php, and updated my composer.json.

"files": [
    "app/Validators/Validators.php"
]

但是，现在任何页面上都不会呈现任何内容.我做错了什么?

However, now nothing renders on any page. What've I done wrong?

推荐答案

尝试以下操作:

1. 制作一个绑定类，您可以在其中实现您想要扩展 Validator 类的每个规则.
2. 制作一个扩展 ServiceProvider 的服务提供者.
3. 在 config/app.php 文件中添加您的自定义验证器提供程序.

1. Make a bind class where you can implement each rule you want extending Validator class.
2. Make a service provider that extends ServiceProvider.
3. Add your custom validator provider at config/app.php file.

您可以像这样在 Services 文件夹中创建绑定:

You can create the bind at Services folder like this:

namespace MyAppServices;

class Validator extends IlluminateValidationValidator{

    public function validateFoo($attribute, $value, $parameters){  
        return $value == "foo"
    }
}

然后，使用服务提供者扩展核心:

Then, use a service provider to extends the core:

namespace MyAppProviders;

use MyAppServicesValidator;
use IlluminateSupportServiceProvider;

class ValidatorServiceProvider extends ServiceProvider{

    public function boot()
    {
        Validator::resolver(function($translator, $data, $rules, $messages)
        {
            return new Validator($translator, $data, $rules, $messages);
        });
    }

    public function register()
    {
    }
}

最后，像这样在 config/app.php 导入你的服务提供者:

Finally, import your service provider at config/app.php like so:

'providers' => [
    ...
    ...
    'MyAppProvidersValidatorServiceProvider';
]
