跳过Laravel 4中的多个输入字段

I have a couple of fields of type array which I want to avoid by using Input::except(). How do I do it? HTML is given below:

<tr>
   <td>
       {{ Form::input('text', 'batch_name[]', null, ['placeholder' =>'Enter batch name']) }}
   </td>
   <td>
       {{ Form::input('date', 'availability_date[]', null) }}
   </td>
   <td>
       <a class="add" title="Add Row" href="#"><img src="{{URL::to('public/assets/images/plus.png')}}" alt=""/></a>
   </td>
</tr>

Following does not work and gives error:

htmlentities() expects parameter 1 to be string, array given

Validator::make(Input::except('_token','batch_name[]','availability_date[]'), $rules);

Ok I found the issue. I was using following in redirection:

return Redirect::to('admin/item/add')
                ->withErrors($validator)
                ->withInput(Input::except('_token'));

By Changing it to following worked:

return Redirect::to('admin/item/add')
                ->withErrors($validator)
                ->withInput(Input::except('_token','batch_name','availability_date'));
