title: Validation of array form fields in laravel 4 error
body: <p>How can we validate form fields that are arrays? Take a look at the following code</p>
  
  <p>UserPhone Model:</p>
  
  
  
  <pre class="lang-php prettyprint-override"><code> public static $rules= array(
      'phonenumber'=&gt;'required|numeric',
      'isPrimary'=&gt;'in:0,1'
  )
  ...........
  </code></pre>
  
  <p>UserController:</p>
  
  <pre class="lang-php prettyprint-override"><code>$validation = UserPhone::validate(Input::only('phonenumber')));
  
  
      if($validation-&gt;passes())
        {
           $allInputs = Input::only('phonenumber','tid');
           $loopSize = sizeOf($allInputs);
  
           for($i=0;$i&lt;$loopSize;$i++)
           {
  
           $phone = UserPhone::find($allInputs['tid'][$i]);
           $phone-&gt;phonenumber = $allInputs['phonenumber'][$i];
           $phone-&gt;save();
  
          }
  
       return Redirect::to('myprofile')-&gt;with('message','Update OK');
  
    }
    else
    {
       return Redirect::to('editPhone')-&gt;withErrors($validation);
  
    } 
  
  }
  </code></pre>
  
  <p>the <code>$validation</code> comes from a BaseModel which extends Eloquent.</p>
  
  <p>In my view:</p>
  
  <pre class="lang-php prettyprint-override"><code> &lt;?php $counter=1; ?&gt;
            @foreach($phones as $thephone)
  
             &lt;section class="col col-12"&gt;
                &lt;label class="label"&gt;Phone Number {{$counter++}}&lt;/label&gt;
                &lt;label class="input"&gt;
                &lt;i class="icon-append icon-phone"&gt;&lt;/i&gt;
                   {{Form::text('phonenumber[]',$thephone-&gt;phonenumber)}}
                   {{Form::hidden('tid[]',$thephone-&gt;id)}}
                &lt;/label&gt;
              &lt;/section&gt;
            @endforeach
  </code></pre>
  
  <p>Everything is working fine and I get all the phone numbers I want in the Update Form, but I cannot update the model because the validation fails with the  message "Phonenumber must be a number".</p>
  
  <p>I know that there is not a simple solution for validating array form fields and I tried to extend the validator class but with no success.</p>
  
  <p>How can I validate this kind of fields?</p>
