title: is isset method different for a drop down menu than a text input?
body: <p>If I use <code>isset()</code> for a text input then I write it like this:</p>
  
  <p><code>$newpass = (isset($_POST['newpass'])) ? $_POST['newpass'] : '';</code></p>
  
  <p>Now if I have a drop down menu like below:</p>
  
  <pre><code>&lt;select name="students"&gt;
  &lt;option value=""&gt;Please Select&lt;/option&gt;
  &lt;option value="john"&gt;John Doe&lt;/option&gt;
  &lt;option value="Mike"&gt;Mike Smith&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Then can I use the same type of isset as I have used for text input:</p>
  
  <p><code>$studentsdrop = (isset($_POST['students'])) ? $_POST['students'] : '';</code></p>
  
  <p>or is the isset different fro a drop down menu?</p>
