Extra freight fee on COD module

[dixxy]

Anyone know how to add a extra freight fee on the Cash On Delivery module?

I have solved this temporarily by making a new carrier set up with freight including the COD-fee that our local postal service requires. The problem by this solution is that the customer have to select the freight called COD first, then select payment option COD. Some customers just select ordinary freight, and then select COD as payment afterwards. The store then don't collect the COD-fee that it supposed to.

A third option for me would be a way of disabling all other payment options after the customer select the COD carrier/freight that i made.

Hopefully someone knows how to add an extra freight fee on the COD module..

I had your same problem. After trying some modules that I found here I realized that none was working fine on my PS 1.4. So, while waiting for updates for those modules, I found a workaround to add a fee on COD payments.

First of all I've created a product called "COD fee" or something like, and put it in a hidden category.

Next I've made few changes on PS code:

in file modules/cashondelivery/validation.php

right after

if (!Validate::isLoadedObject($customer))
   Tools::redirectLink(__PS_BASE_URI__.'order.php?step=1');

put (remembering to replace "put-here-your-hidden-product-ID" with the actual ID)

Db::getInstance()->AutoExecute(_DB_PREFIX_.'cart_product', array('id_product' => put-here-your-hidden-product-ID,
               'id_product_attribute' => 0, 'id_cart' => (int)($cart->id),
               'quantity' => 1, 'date_add' => date('Y-m-d H:i:s')), 'INSERT');
$cart->update(true);    

in file controllers/OrderController.php

after

public function process()
   {
       parent::process();

add

global $orderTotal;

and after

case 3:
               if(Tools::isSubmit('processCarrier'))
                   $this->processCarrier();
               $this->autoStep();
               /* Bypass payment step if total is 0 */
               if (($id_order = $this->_checkFreeOrder()) AND $id_order)
               {
                   if (self::$cookie->is_guest)
                   {
                       $email = self::$cookie->email;
                       self::$cookie->logout(); // If guest we clear the cookie for security reason
                       Tools::redirect('guest-tracking.php?id_order='.(int)$id_order.'&email;='.urlencode($email));
                   }
                   else
                       Tools::redirect('history.php');
               }

put (remembering to replace "put-here-your-hidden-product-ID" with the actual ID)

self::$cart->deleteProduct(put-here-your-hidden-product-ID, 0, 0);
$orderTotal = self::$cart->getOrderTotal();

This will add the hidden product to the cart when user selects COD payment method and will remove it if he returns to payment selection step.

Obviously this is only a workaround... Seems to work, try it carefully before going in production environment.
