如何自定义错误消息

Question

大家好，感谢您的帮助。我想自定义验证错误消息和 最终为每种语言创建不同的版本，这可能吗？

这是我的代码在他的实际状态。

namespace App;

use Respect\Validation\Exceptions\ValidationException;
use Respect\Validation\Exceptions\NestedValidationException;
use Respect\Validation\Validator as v;

class Validator {

    private $messages = [
        'lastname',
        'firstname',
        'phone',
        'email',
        'message'
    ];

    //other functions and declarations of my class.

    private function validationData() {
        $rule = null;

        switch ($this->page) {
            case 'contact';
                $rule = v::key('lastname', v::notEmpty()
                                            ->alpha("-'"))
                         ->key('firstname', v::optional(v::alpha("-'")))
                         ->key('phone', v::optional(v::phone()))
                         ->key('email', v::email())
                         ->key('message', v::optional(v::length(5, 500)));
                break;
            default;
                break;
        }
        try {
            $rule->assert($this->data);
        } catch (ValidationException $exception) {
            var_dump($exception->findMessages($this->messages));
        }            
     }
 }

它 returns 我认为：

array(5) {
["lastname"]=> string(51) "lastname must contain only letters (a-z) and ""-'"""
["firstname"]=> string(0) ""
["phone"]=> string(38) "phone must be a valid telephone number"
["email"]=> string(25) "email must be valid email"
["message"]=> string(44) "message must have a length between 5 and 500"
}

我需要保留验证结果的这种结构。因为我需要字段的名称才能在客户端显示它们。

再次感谢，

你可以用 Respect/Validation 来完成。

I'll like to custom error messages for validation

定义消息时，只需将其设为关联数组，键代表错误，值代表将要显示的消息：

private $messages = [
  'lastname' => 'Error for lastname',
  'firstname' => 'Custom error for firstname',
  'phone' => 'Custom error  for phone',
  'email' => 'Custom error for email',
  'message' => 'Custom error for message'
];

and eventually to create different version for each language

您可以创建一个自定义函数，将消息转换成您想要的任何语言：

$translateMessage = function($message){
    $language = 'it'; //Retrieve your language here or use 'en' if you want your custom messages
    $messages = [
        'Key {{name}} must be present' => [
            'en' => 'Key {{name}} SHOULD be present',
            'it' => 'La chiave {{name}} deve essere presente'
        ],
        '{{name}} must be a string' => [
            'en' => '{{name}} SHOULD be a magic custom string',
            'it' => '{{name}} deve essere una stringa'
        ],
        '{{name}} must contain only letters (a-z)' => [
            'en' => '{{name}} SHOULD contain only my letters (a-z)',
            'it' => '{{name}} deve contenere solo lettere (a-z)'
        ],
        '{{name}} must contain only letters (a-z) and "{{additionalChars}}"' => [
            'en' => '{{name}} must contain only letters (a-z) and "{{additionalChars}}',
            'it' => '{{name}} deve contenere solo lettere (a-z) e "{{additionalChars}}"'
        ]
    ];
    return $messages[$message][$language];
};

然后在你的 catch 块中使用它：

catch (ValidationException $exception) {
    $exception->setParam('translator', $translateMessage);
    var_dump($exception->findMessages($this->messages));
}
