How to add a Fee to COD payment?

Recommended Posts

Hello,

 

I just installed the responsive template (works fantastic) together with the new OSC version

 

Could somebody please help me modify the COD payment module so that it adds a 6.50 EUR fee for orders paid via COD?

 

In which function would I add my code to add a fee?

 

Here is the code of cod.php for reference:

    var $code, $title, $description, $enabled;


    function cod() {
      global $order;


      $this->code = 'cod';
      $this->title = MODULE_PAYMENT_COD_TEXT_TITLE;
      $this->description = MODULE_PAYMENT_COD_TEXT_DESCRIPTION;
      $this->sort_order = defined('MODULE_PAYMENT_COD_SORT_ORDER') ? MODULE_PAYMENT_COD_SORT_ORDER : 0;

      if ( $this->enabled === true ) {
        if ( isset($order) && is_object($order) ) {
          $this->update_status();

    function update_status() {
      global $order;


      if ( ($this->enabled == true) && ((int)MODULE_PAYMENT_COD_ZONE > 0) ) {

            $check_flag = true;

    }
  }
?>
