title: Does isset work with GET?
body: <p>I know this kinda seems like a stupid question and with more research i might be able to find the answer but i have a deadline to please help. </p>
  
  <p>Using codeigniter im trying to see if the 'ID' in the url is 'uID' (user id) or 'sID' (system id).</p>
  
  <p>the code im using is:</p>
  
  <pre><code>    if(isset($this-&gt;input-&gt;get('uID'))) {
          $getID = $this-input-&gt;get('uID');
      } else {
          $getID = $this-&gt;input-&gt;get('sID');
      }
  </code></pre>
  
  <p>when i use that i get a server error saying website is temporarily down or under constrcution. Any ideas? </p>
  
  <p>Thanks in advance for the help. Usually i would spend more time searching for the answer myself but i just dont have time tonight.</p>
