title: PHP and select list
body: <p>I have this html code:   </p>
  
  <pre><code>&lt;select name='plan_id'&gt;  
   &lt;option value="1" &gt;Basic&lt;/option&gt;  
   &lt;option value="2" selected="selected"&gt;Basic Gold&lt;/option&gt;  
   &lt;option value="3" &gt;Silver&lt;/option&gt;  
  &lt;/select&gt;  
  </code></pre>
  
  <p>and php code:  </p>
  
  <pre><code>$from = $_POST['plan_id'];  
  var_dump($from);  
  </code></pre>
  
  <p>and I got string <code>''</code> (length=0).  </p>
  
  <p>How do I fix it to get the selected value?</p>
