title: laravel 5.4 auth register custom error message
body: <p>Im sorry i am new for laravel, but this is strange,</p>
  
  <p>i want to use custom error message in validation of error register,
  in my registercontroller :</p>
  
  <pre><code>$messages = [
          'vbadminEmail.required'      =&gt; 'Email has already been taken this is customize error.', 
      ];
  
      $result = Validator::make($data, [            
          'vbadminEmail' =&gt; 'required|email|max:255|unique:admin_user,user_email',
          'vbadminPassword' =&gt; 'required|min:6|confirmed',
      ],$messages); 
  </code></pre>
  
  <p>when i test and debug the result :</p>
  
  <p><a href="https://i.stack.imgur.com/EQWWW.jpg" rel="nofollow noreferrer">debug the error arrays</a></p>
  
  <p>it still used the general format, not the "Email has already been taken this is customize error"</p>
  
  <p>please help me how to fix it
  thank you</p>
