title: Select disable doesn't pass the value correctly
body: <p>Please help me.
  I use Codeigniter.</p>
  
  <p>In VIEW i have</p>
  
  <pre><code>'&lt;select name="sender[]" style="width:150px" class="chzn-select" disabled='disabled'&gt;
  &lt;?php foreach($statments as $statement): ?&gt;
  &lt;option value="&lt;? echo $statement-&gt;id; ?&gt;" &lt;?php echo ($statement-&gt;id==$pris-&gt;sender)?"selected='selected'":""; ?&gt;&gt;&lt;?php echo $statement-&gt;name; ?&gt;'&lt;?php endforeach; ?&gt;
  </code></pre>
  
  <p>If i use "disabled" it passes "sender" as NULL. 
  if i remove "disabled" it works fine, but i need not active select.  </p>
