【问题描述】：

想检查我是否已经制作了一个 CustomValidator.php 来处理我所有的附加验证规则，但问题是我应该如何返回自定义错误消息？这就是我为我的 CustomValidator.php 文件所做的，

<?php namespace App\Validators\CustomValidator;

use Illuminate\Validation\Validator;
use Auth;

class CustomValidator extends Validator 
{
    public function validateVerifyPassword($attribute, $value, $parameters)
    {
        $currentUser = Auth::user();
        $credentials = array ('email' => $currentUser->email, 'password' => $currentUser->password);

        return Auth::validate($credentials);
    }

    protected function replaceVerifyPassword($message, $attribute, $rule, $parameters)
    {
        return str_replace($attribute, $parameters[0], $message);
    }
}

这就是我在 FormRequest.php 中定义自定义错误消息的方式

public function messages()
{
    return [
        'login_email.required'              =>  'Email cannot be blank',
        'old_password.required'             =>  'You need to provide your current password',
        'old_password.between'              =>  'Your current password must be between :min and :max characters',
        'old_password.verifyPassword'       =>  'Invalid password',
        'password.required'                 =>  'Password is required.',
        'password.between'                  =>  'Your password must be between :min and :max characters',
        'password_confirmation.required'    =>  'You need to retype your password',
        'password_confirmation.same'        =>  'Your new password input do not match',
        'g-recaptcha-response.required'     =>  'Are you a robot?',
        'g-recaptcha-response.captcha'      =>  'Captcha session timeout'
    ];
}

注意到验证部分正在工作，只是它不会传递自定义错误消息，它返回给我一个错误

CustomValidator.php line 18:
Undefined offset: 0

位于$parameter[0] 部分

找到了解决方案，显然当您尝试执行验证时，它出现的错误消息将携带该验证规则错误消息的关键。我们以下图为例，

请注意，在电子邮件字段下，有一个错误消息validation.current_email 错误，current_email 是用于在 FormRequest 中指定您的自定义错误消息的键。所以基本上你所做的是在我的 FormRequest.php 中，我添加了这样的错误消息：

public function messages()
{
    return [
        'new_email.required'                =>  'New email cannot be blank',
        'new_email.current_email'           =>  'This is the current email adderess being used',
        'password.required'                 =>  'You need to provide your current password',
        'password.between'                  =>  'Your current password must be between :min and :max characters',
        'password.verify_password'          =>  'Invalid password',
        'g-recaptcha-response.required'     =>  'Are you a robot?',
        'g-recaptcha-response.captcha'      =>  'Captcha session timeout'
    ];
}

这将是下图中的最终结果：
