如何在 laravel 表单验证错误消息中给出自定义字段名称

发布于08月08日

我在试着用拉威尔进行表格验证. 我的表单中有一个名为"Category"的输入文本字段，字段名为"cat"，缩写为"cat".

我这样定义了验证规则.

public static $rules=array(
         "name"=>"required|min:3",
          "cat"=>"required"
           );

当验证失败时，我会收到这样的错误消息

The name field is required.
The cat field is required.

But i want to display it as "The category field is required" instead of 'cat'.
How can i change 'cat' to 'Category' in error message ?.

推荐答案

您可以为您的字段指定自定义错误消息，如下所示.

$messages = array(
    'cat.required' => 'The category field is required.',
);

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

Please see Custom Error Messages section in laravel documentation for more information.

Or you can keep a mapping for your field names like below. And you can set those into you validator. So you can see descriptive name instead of real field name.

$attributeNames = array(
   'name' => 'Name',
   'cat' => 'Category',     
);

$validator = Validator::make ( Input::all (), $rules );
$validator->setAttributeNames($attributeNames);
