title: Codeigniter form_open_multipart() displays blank
body: <p>Been trying out codeigniter and wanted to create a very simple single file upload using the upload class. However I keep getting a blank page when trying to create a form using form_open_multipart. I've been looking around, but I can't seem to find out how to make this work.</p>
  
  <p>The HTML uploadPage.php</p>
  
  <pre><code>&lt;body&gt;
  
  
      &lt;?php echo form_open_multipart('upload/theUpload');?&gt;
      &lt;input type="file" name="userfile"&gt;
      &lt;input type="submit" name="submit" value="Upload File"&gt;
      &lt;/form&gt;
  
  &lt;/body&gt;
  </code></pre>
  
  <p>The controller upload.php</p>
  
  <pre><code>&lt;? if ( ! defined('BASEPATH')) exit('No direct script access allowed');
  
  class upload extends CI_Controller{
  
      function index(){
          $this-&gt;load-&gt;view("uploadPage");
  
      }
  
      function theUpload(){
  
  
      }       
  
  
  
  
  
  }
  </code></pre>
