How to modify Chinese validation rules in Laravel

It is a very common requirement to modify Chinese validation rules in Laravel, especially when developing projects in a Chinese environment. By default, Laravel's validation rules are in English, but we can modify them to Chinese rules through a custom validator to make the code clearer and easier to understand. The specific steps, including code examples, are described below:

1. Create a custom validator

First, we need to create a custom validator , in order to define Chinese validation rules there. In Laravel, you can use the Artisan command to generate a custom validator:

php artisan make:validator CustomValidator

This will generate a CustomValidator.php file in the app/Validators directory, and we will define Chinese validation rules in this file.

2. Define Chinese validation rules

In the CustomValidator.php file, we can define Chinese validation rules, for example:

namespace AppValidators;

use IlluminateValidationValidator;

class CustomValidator extends Validator
{
    protected $customMessages = [
        'required' => '必填项',
        'email' => '邮箱格式不正确',
        'numeric' => '必须为数字',
        // 可根据需要添加更多中文验证规则
    ];
}

Here, we use the $customMessages array to define Chinese validation rules, such as changing 'required' to 'required', 'email' to 'email format is incorrect', etc.

3. Register a custom validator

Next, we need to register the custom validator in the boot method of AppServiceProvider to let Laravel know about us To use this custom validator. In the AppServiceProvider.php file:

namespace AppProviders;

use IlluminateSupportServiceProvider;
use AppValidatorsCustomValidator;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        $this->app['validator']->resolver(function($translator, $data, $rules, $messages) {
            return new CustomValidator($translator, $data, $rules, $messages);
        });
    }

    public function register()
    {
        //
    }
}

This code registers the CustomValidator into Laravel so that the Chinese rules we defined can be used during validation.

4. Use Chinese validation rules

Finally, we can use Chinese validation rules directly in controllers or form requests:

$request->validate([
    'email' => 'required|email',
    'password' => 'required|min:6',
], [
    'email.required' => '邮箱为必填项',
    'password.required' => '密码为必填项',
    'password.min' => '密码长度不能少于6个字符',
]);

Through the above steps, we have successfully modified the Chinese verification rules in Laravel. This can make the code more readable and understandable, and make development in a Chinese environment more convenient. Hope this helps!
