title: Laravel : Form select option value is always NULL when submitting
body: <p>I have a form where I put de id's of my bands table inside a select option. When I select an id in the dropdownlist and try to submit the form, the value always remains NULL. How can I retrieve the value I selected?</p>
  
  <p>create.blade.php file :</p>
  
  <pre><code>&lt;form&gt;
      &lt;select name="band_id"&gt;
          @foreach ($bands as $band) 
              &lt;option value="{{ $band-&gt;band_id }}"&gt;{{ $band-&gt;band_id }}&lt;/option&gt;
          @endforeach
      &lt;/select&gt;
      &lt;input type="submit" value="Submit"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>My Bandcontroller inside my store action :</p>
  
  <pre><code>$bands-&gt;band_id = $input['band_id'];
  </code></pre>
