如果有办法检查验证器是否由于唯一规则而特别失败？
原文链接：https://www.f2er.com/laravel/133632.html$rules = array(
'email_address' => 'required|email|unique:users,email','postal_code' => 'required|alpha_num',);
$messages = array(
'required' => 'The :attribute field is required','email' => 'The :attribute field is required','alpha_num' => 'The :attribute field must only be letters and numbers (no spaces)'
);
$validator = Validator::make(Input::all(),$rules,$messages);
if ($validator->fails()) {
在外行人看来,我基本上想知道：“验证失败了,因为email_address不是唯一的吗？”
