title: Form submit buttons not passing values
body: <p>I have a basic form that includes 3 submit buttons.  </p>
  
  <pre><code>&lt;form action="/signups/wizard/location" id="SignupForm" method="post" accept-charset="utf-8"&gt;
  &lt;div style="display:none;"&gt;&lt;input type="hidden" name="_method" value="POST"&gt;&lt;/div&gt;
  Street: &lt;input name="data[Location][street]" maxlength="200" type="text" value=""&gt;
  Apartment: &lt;input name="data[Location][apartment]" value=""&gt;
  City:&lt;input name="data[Location][city]" maxlength="50" type="text" value=""&gt;
  &lt;div class="submit"&gt;
      &lt;input name="Previous" type="submit" value="Previous"&gt;      
      &lt;input type="submit" value="Continue"&gt;
      &lt;input name="Cancel" type="submit" value="Cancel"&gt;  
  &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>When I submit that form, I expected the input fields for submit buttons to pass their data to $_POST, however I only see Location in the array.</p>
  
  <p>Here are $_POST's contents:</p>
  
  <pre><code>array(
      '_method' =&gt; 'POST',
      'data' =&gt; array(
          'Location' =&gt; array(
              'street' =&gt; '',
              'apartment' =&gt; '',
              'city' =&gt; ''
          )
      )
  )
  </code></pre>
  
  <p><strong>UPDATE</strong>
  I disabled javascript and the values appear in $_POST.  Is there an easy way to determine what script could be removing this?</p>
