在Laravel 4中扩展Validation类时如何指定默认错误消息 [英] How to specify the default error message when extending the Validation class in Laravel 4

问题描述

我使用made使用extend函数来扩展和在Laravel 4的Validation Class上添加自定义规则.

I use made use the extend function to extend and adding custom rules on the Validation Class of Laravel 4.

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

当我使用新创建的自定义扩展名验证规则时，如果规则失败，它将返回validation.foo.在Laravel 4中扩展验证类时，是否可以定义通用/默认消息?

When I validate the rule using the newly created custom extension, it returns validation.foo if the rule fails. Is there a way to define a generic/ default message when extending the validation class in Laravel 4?

推荐答案

Laravel 4文档明确说明，您需要为自定义规则定义错误消息.

The Laravel 4 docs specifically state you need to define an error message for your custom rules.

您有两个选择；

选项1:

$messages = array(
    'foo' => 'The :attribute field is foo.',
);

$validator = Validator::make($input, $rules, $messages);

选项2:

在语言文件中指定您的自定义消息，而不是将其直接传递给Validator.为此，请将您的消息添加到app/lang/xx/validation.php语言文件中的自定义数组:

Specify your custom messages in a language file instead of passing them directly to the Validator. To do so, add your messages to custom array in the app/lang/xx/validation.php language file:

'custom' => array(
    'foo' => array(
        'required' => 'We need to know your foo!',
    ),
),
