Laravel 4自定义验证规则 - 在哪里扩展验证器？

Question

我想制作一个自定义验证规则.我的模型目前看起来像这样:

protected $rules = array(
    'first_name'  => 'required',
    'last_name'   => 'required',
    'ssn'         => 'required|integer|min:4|max:4',
    'email'       => 'required|email',
    'dob'         => 'required|checkAge',
    'phone'       => 'required',
    'street'      => 'required',
    'postal_code' => 'required|integer|min:4',
    'city'        => 'required'
);

但是我必须放置自定义验证规则？我已经读过我需要扩展它的Validator.为此,我创建了一个简单的功能

Validator::extend('foo', function($attribute, $value, $parameters)
{
    return $value == 'foo';
});

我不知道在哪里检查它？

也许有人可以帮助我.

谢谢

我是通过在/ app中创建验证文件夹来实现的,其中包含任何自定义验证文件.
我通过编辑app/start/global.php自动加载.

ClassLoader::addDirectories(array(
    app_path() . '/commands',
    app_path() . '/controllers',
    app_path() . '/models',
    app_path() . '/presenters',
    app_path() . '/validation',
    app_path() . '/database/seeds',
));

我还在这个文件中注册了解析器;

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

自定义验证器类示例(在验证文件夹中);

<?php

class CoreValidator extends Illuminate\Validation\Validator
{

    protected $implicitRules = array('Required', 'RequiredWith', 'RequiredWithout', 'RequiredIf', 'Accepted', 'RequiredWithoutField');

    public function __construct(\Symfony\Component\Translation\TranslatorInterface $translator, $data, $rules, $messages = array())
    {
        parent::__construct($translator, $data, $rules, $messages);
        $this->isImplicit('fail');
    }

    public function validatePostcode($attribute, $value, $parameters = null)
    {
        $regex = "/^((GIR 0AA)|((([A-PR-UWYZ][0-9][0-9]?)|(([A-PR-UWYZ][A-HK-Y][0-9][0-9]?)|(([A-PR-UWYZ][0-9][A-HJKSTUW])|([A-PR-UWYZ][A-HK-Y][0-9][ABEHMNPRVWXY])))) [0-9][ABD-HJLNP-UW-Z]{2}))$/i";
        if (preg_match($regex, $value)) {
            return true;
        }
        return false;
    }
}

并在app/lang/en/validation.php中将自定义错误消息添加到数组中

return array(
...
"postcode" => "Invalid :attribute entered.",
...
)

应用程序启动后,可以立即添加扩展.我要做的就是创建一个validations.php在同级别的文件routes.php和filters.php然后加入到我的app/start/global.php:

require app_path().'/filters.php'; /// this one is already there...
require app_path().'/validations.php';
