Steps to implement Chinese verification modifications in Laravel

In the Laravel framework, it is crucial to verify the data entered by the user. Normally, Laravel provides English validation rules by default, but if we need to change the validation rules to Chinese, we need to do some extra steps. The following will introduce in detail the steps to implement Chinese verification modifications in Laravel and provide specific code examples.

Step 1: Install Laravel

If Laravel has not been installed yet, please run the following command on the command line to install Laravel:

composer create-project --prefer-dist laravel/laravel your-project-name

Step 2: Create a Chinese language pack file

Create a new language pack file validation.php in the resources/lang/zh_CN directory. In this file, we will add validation rules for Chinese translation.

// resources/lang/zh_CN/validation.php
return [
    'accepted'             => ':attribute必须接受',
    'active_url'           => ':attribute不是一个有效的URL',
    'after'                => ':attribute必须是一个在 :date 之后的日期',
    // 添加更多的中文验证规则
];

Step 3: Configure the Chinese language pack

In the config/app.php file, locale is set to 'zh_CN', to ensure that Laravel uses the Chinese language pack for translation of validation rules.

'locale' => 'zh_CN',

Step 4: Use Chinese validation rules

Where data verification is required, we can use the built-in validator provided by LaravelValidator To implement Chinese verification rules.

use IlluminateSupportFacadesValidator;

public function validateData(Request $request)
{
    $validator = Validator::make($request->all(), [
        'name' => 'required|string|max:255',
        'email' => 'required|email',
        // 更多的验证规则
    ]);

    if ($validator->fails()) {
        return redirect()->back()->withErrors($validator)->withInput();
    }

    // 验证通过的逻辑
}

Step 5: Customize Chinese error messages

Where you need to customize Chinese error messages, you can do so by extending the Validator class. Create a new Chinese validator class ChineseValidator.php, introduce this class, and customize specific Chinese error messages as needed.

// app/Validators/ChineseValidator.php

namespace AppValidators;

use IlluminateSupportMessageBag;
use IlluminateValidationValidator;

class ChineseValidator extends Validator
{
    public function __construct(Translator $translator, array $data, array $rules, array $messages = [], array $customAttributes = [])
    {
        parent::__construct($translator, $data, $rules, $messages, $customAttributes);
    }

    protected function replaceXXX($message, $attribute, $rule, $parameters)
    {
        return str_replace(':xxx', '自定义中文错误信息', $message);
    }
}

// 在你的控制器或服务提供者中添加以下代码来覆盖 Laravel 自带验证器
$this->app['validator'] = $this->app->share(function ($app) {
    $validator = new ChineseValidator($app['translator'], $app);
    $validator->setPresenceVerifier($app['validation.presence']);
    return $validator;
});

Summary

Through the above steps, we successfully implemented the process of modifying and using Chinese validation rules in Laravel. First, create a Chinese language pack file, configure the Chinese language pack, and use Chinese verification rules. Finally, you can further optimize the user experience by customizing Chinese error messages. I hope the above content can help you realize the Chinese verification and modification function.
