如何通过扩展Laravel 5中的Validator类来添加自定义错误消息？

Question

I want to validate alpha_dash(Alphabets and Spaces) and the code below works fine

Validator::extend('alpha_spaces', function($attribute, $value)
{
    return preg_match("/^[a-z0-9 .\-]+$/i", $value);
});

but the error it gives is not user friendly :

validation.alpha_spaces

How can change this message?

This is the method where it is posts

public function create(Request $request)
{

    $this->validate($request, [
        'title' => 'required|alpha_spaces|max:255',
    ]);


}

Thanks!

Just add your custom error message as an array element to resources/lang/xx/validation.php :

'alpha_spaces' => 'The :attribute may only contain letters, numbers and spaces.',
