title: htmlspecialchars() expects parameter 1 to be string, array given
body: <p>I have a form and if i submit the form with all the right data everything goes perfectly fine... but if I intentionally make any flaw </p>
  
  <p>(validation for example <code>'title' =&gt; 'required|min:2'</code>) </p>
  
  <p>and I put only one character for title or if I miss any required field I get this error:</p>
  
  <pre><code>htmlspecialchars() expects parameter 1 to be string, array given
  </code></pre>

  <p>I have figured out that the problem is with this select box </p>
  
  <pre><code>{!! Form::select('item[0][]', $items, null, ['class' =&gt; 'form-control', 'required']) !!}
  </code></pre>
  
  <p>and I even tried to use a normal select box without form helper {!! !!}</p>
  
  <p>But I still get the same error!</p>
  
  <p>So the problem is somewhere with validation when there is a nested array....is there a way to fix this?</p>
