您使用的是什么版本的Laravel？如果你正在使用Laravel 5.2，或者你不介意更新到它，有一个现成的解决方案。

阵列验证

在Laravel 5.2中，验证数组形式的输入字段要容易得多。对于例如，验证给定数组输入字段中的每个电子邮件是否唯一，您可以执行以下操作：

$validator = Validator::make($request->all(), [
    'person.*.email' => 'email|unique:users'
]);

同样，在指定验证时可以使用*字符语言文件中的消息，使用单个基于数组的字段的验证消息：

'custom' => [
    'person.*.email' => [
        'unique' => 'Each person must have a unique e-mail address',
    ]
],

Laravel新闻的另一个例子：

假设您有一个表单，其中包含一组输入字段，如下所示：

<p>
<input type="text" name="person[1][id]">
<input type="text" name="person[1][name]">
</p>
<p>
<input type="text" name="person[2][id]">
<input type="text" name="person[2][name]">
</p>

在Laravel 5.1中，添加验证规则需要循环通过和单独添加规则。不必做所有的事情被"放大"成这样：

$v = Validator::make($request->all(), [
  'person.*.id' => 'exists:users.id',
  'person.*.name' => 'required:string',
]);

因此，如果你不想使用Laravel 5.2，你将不得不手动进行，如果你更新到Laravel 520，你可以使用新的阵列验证，它将是这样的：

protected $rules = [
        ValidatorInterface::RULE_CREATE => [
        'users_id' => 'required',
        'user_profiles_id' => 'required',
        'categories_id' => 'required',
        'product_name' => 'required|max:100',
        'product_description' => 'required|max:1000',
        'tags' => 'required',
        'image_count'=>'required|integer',
        'creation_mode'=>'required|integer',
        'skus.*.is_shippable'=>'in:y,n',
        'skus.*.actual_price'=>'regex:/^'s*(?=.*[1-9])'d*(?:'.'d{1,2})?'s*$/',
        'skus.*.selling_price' => 'regex:/^'s*(?=.*[1-9])'d*(?:'.'d{1,2})?'s*$/',
        'skus.*.quantity_type' => 'sometimes|required|in:finite,infinite,bucket',
        'skus.*.quantity_total' => 'integer|required_if:skus.quantity_type,finite', 
        'skus.*.bucket_value'=>'in:instock,soldout,limited|required_if:skus.quantity_type,bucket',
        'skus.*.sort_order'=> 'required|integer'
        ],
        ValidatorInterface::RULE_UPDATE => [
        ]
    ];

编辑

添加此额外验证逻辑的最佳方法是扩展Validator类，创建CustomValidator，这可能有点过头了，但当Laravel 5.2发布时，您可以删除CustomValidator并继续使用Laravel的5.2 Validator，而无需对代码进行任何更改。

如何？首先，我们在app/下创建了一个文件夹。我决定将此文件夹命名为Validator。您可以随心所欲地命名它，只需记住更新以下类的名称空间。接下来，我们将在此文件夹中创建3.php文件CustomValidator.php、CustomValidatorServiceProvider.php和Factory.php。

自定义验证器.php

<?php
namespace App'Validator;
use Illuminate'Support'Arr;
use Illuminate'Support'Str;
use Illuminate'Validation'Validator;
use Symfony'Component'Translation'TranslatorInterface;
class CustomValidator extends Validator
{
    /**
     * Create a new Validator instance.
     *
     * @param  'Symfony'Component'Translation'TranslatorInterface  $translator

     * @param  array  $messages
     * @param  array  $customAttributes
     * @return void
     */
    public function __construct(TranslatorInterface $translator, array $data, array $rules, array $messages = [], array $customAttributes = [])
    {
        $this->translator = $translator;
        $this->customMessages = $messages;
        $this->data = $this->parseData($data);
        $this->customAttributes = $customAttributes;
        // Explode the rules first so that the implicit ->each calls are made...
        $rules = $this->explodeRules($rules);
        $this->rules = array_merge((array) $this->rules, $rules);
    }
    /**
     * Explode the rules into an array of rules.
     *
     * @param  string|array  $rules
     * @return array
     */
    protected function explodeRules($rules)
    {
        foreach ($rules as $key => $rule) {
            if (Str::contains($key, '*')) {
                $this->each($key, $rule);
                unset($rules[$key]);
            } else {
                $rules[$key] = (is_string($rule)) ? explode('|', $rule) : $rule;
            }
        }
        return $rules;
    }

    /**

     *

     *
     * @throws 'InvalidArgumentException
     */
    public function each($attribute, $rules)
    {
        $data = Arr::dot($this->data);
        foreach ($data as $key => $value) {
            if (Str::startsWith($key, $attribute) || Str::is($attribute, $key)) {
                foreach ((array) $rules as $ruleKey => $ruleValue) {
                    if (! is_string($ruleKey) || Str::endsWith($key, $ruleKey)) {
                        $this->mergeRules($key, $ruleValue);
                    }
                }
            }
        }
    }

    /**

     *

     */
    protected function getInlineMessage($attribute, $lowerRule, $source = null)
    {
        $source = $source ?: $this->customMessages;
        $keys = ["{$attribute}.{$lowerRule}", $lowerRule];
        // First we will check for a custom message for an attribute specific rule
        // message for the fields, then we will check for a general custom line
        // that is not attribute specific. If we find either we'll return it.
        foreach ($keys as $key) {
            foreach (array_keys($source) as $sourceKey) {
                if (Str::is($sourceKey, $key)) {
                    return $source[$sourceKey];
                }
            }
        }
    }
    /**
     * Get the custom error message from translator.
     *
     * @param  string  $customKey
     * @return string
     */
    protected function getCustomMessageFromTranslator($customKey)
    {
        $shortKey = str_replace('validation.custom.', '', $customKey);
        $customMessages = Arr::dot(
            (array) $this->translator->trans('validation.custom')
        );
        foreach ($customMessages as $key => $message) {
            if ($key === $shortKey || (Str::contains($key, ['*']) && Str::is($key, $shortKey))) {
                return $message;
            }
        }
        return $customKey;
    }
}

这个自定义验证器拥有Laravel 5.2上所做的所有更改，您可以在这里查看

现在，由于我们有了一个新的CustomValidator类，我们必须找到一种使用它的方法，为此，我们必须扩展ValidatorServiceProvider和Validator工厂。

自定义验证器服务提供者.php

<?php
namespace App'Validator;

class CustomValidatorServiceProvider extends 'Illuminate'Validation'ValidationServiceProvider
{
    /**
     * Register the validation factory.
     *
     * @return void
     */
    protected function registerValidationFactory()
    {
        $this->app->singleton('validator', function ($app) {
            $validator = new Factory($app['translator'], $app);
            // The validation presence verifier is responsible for determining the existence
            // of values in a given data collection, typically a relational database or
            // other persistent data stores. And it is used to check for uniqueness.
            if (isset($app['validation.presence'])) {
                $validator->setPresenceVerifier($app['validation.presence']);
            }
            return $validator;
        });
    }
}

Factory.php

<?php
namespace App'Validator;
use App'Validator'CustomValidator as Validator;
class Factory extends 'Illuminate'Validation'Factory
{
    /**
     * Resolve a new Validator instance.
     *
     * @param  array  $data
     * @param  array  $rules
     * @param  array  $messages
     * @param  array  $customAttributes
     * @return App'Test'CustomValidator
     */
    protected function resolve(array $data, array $rules, array $messages, array $customAttributes)
    {
        if (is_null($this->resolver)) {
            return new Validator($this->translator, $data, $rules, $messages, $customAttributes);
        }
        return call_user_func($this->resolver, $this->translator, $data, $rules, $messages, $customAttributes);
    }
}

现在，我们已经扩展了验证以支持嵌套语法sku.*.id

我们只需要将Validator交换到我们的CustomValidator，最后一步是更改文件config/app.php，在ServiceProviders数组中查找ValidatorServiceProvider。只需注释该行并添加我们的扩展服务提供商，如下所示：

....
// Illuminate'Validation'ValidationServiceProvider::class,
App'Validator'CustomValidatorServiceProvider::class,
....

我们之所以将其注释掉，是因为每当您将Laravel 5.1更新到5.2时，您只想取消注释，从列表中删除我们的CustomValidatorServiceProvider，然后删除我们的app/Validator文件夹，因为我们不再需要它了。
