title: CodeIgniter POST variables
body: <p>Anyone know why:</p>
  
  <pre><code>class Booking extends Controller {
  
      function booking()
      {
          parent::Controller();
      }
  
      function send_instant_to_paypal()
      {
          print_r($_POST);
          echo '&amp;lt;hr /&gt;';
          print_r($this-&gt;input-&gt;post());
          echo '&amp;lt;hr /&gt;';
          $id_booking = $this-&gt;input-&gt;post('id_booking');
          $title = $this-&gt;input-&gt;post('basket_description');
          $cost = ($this-&gt;input-&gt;post('fee_per_min') * $this-&gt;input-&gt;post('amount'));
          echo $id_booking;
          echo $title
          echo $cost
      }
  }
  </code></pre>
  
  <p>Will echo post variables in CI for $_POST
  but NOT for $this->input->post();?</p>
  
  <p>I've got 
  $this->input->post() in use and working on a search page elsewhere in the site... but on this page, it's not working..
  here's my form...</p>
  
  <pre>
  &lt;form id="add_funds" action="' . site_url('booking/send_instant_to_paypal') . '" method="post">
  &lt;input type="text" name="amount" id="amount" value="" />
  &lt;input type="hidden" name="id_booking" id="id_booking" value="0" />
  &lt;input type="hidden" name="basket_description" id="basket_description" value="Adding Credit" />
  &lt;input type="hidden" name="fee_per_min" id="fee_per_min" value="' . $fee_per_min . '" />
  &lt;input type="submit" value="Add to basket" />
  &lt;/form>
  </pre>
  
  <p>It's mental ;-p
  Anyone spot anything obviously stupid I'm missing?</p>
