Laravel 具有 "sometimes" 规则的验证程序自定义消息

Laravel Validator custom message with "sometimes" rule

这是我的一段代码,用于验证表单输入:

public function saveData(Request $request){
    $form_data = $request->all();

    $validation_fields = [
        'first_name' => 'required',
        'last_name' => 'required',
        'cod_fisc' => 'sometimes|required|size:16',
        'p_iva' => 'sometimes|required|between:11,13'
    ];

    $errorMsgs = [
        'first_name.required' => 'Il campo Nome è obbligatorio.',
        'last_name.required' => 'Il campo Cognome/Ragione sociale è obbligatorio.',
        'cod_fisc.required' => 'Il campo Codice Fiscale deve contenere 16 caratteri',
        'p_iva.required' => 'Il campo Partita Iva deve contenere 11 o 13 caratteri',
    ];

    $validator = Validator::make($form_data, $validation_fields, $errorMsgs);

    ....
}

整个项目都是为意大利人编写的,因此所有消息都必须使用意大利语。 一切正常,但绑定到“有时”规则的 cod_fiscp_iva 的两个规则以英文显示。我的自定义错误消息被忽略了。

为什么?

我在搜索您的问题时发现了这个 link:https://laracasts.com/discuss/channels/laravel/sometimes-validator-with-custom-message

其中包含类似的问题。初始代码是

$v = Validator::make(
                    $request->all(),
                    [ 'first_name' => 'required|max:60'],
                    ['first_name.required' => 'First name is really required, yo']
);

$v->sometimes('last_name', 'required|in:fake', function($input){
                    return true;
});

解决方案是

$v = Validator::make(
                    $request->all(),
                    [ 'first_name' => 'required|max:60'],
                    ['first_name.required' => 'First name is really required, yo'],
                    ['last_name.in' => 'Last name must be fake, too']
);

$v->sometimes('last_name', 'required|in:fake', function($input){
                    return true;
});

显然你可以在 Validator::make 的结果上调用 sometimes function 并传递字段名称、验证器签名和布尔值 function.
