Magento Cart: Check for Recycle Bins

Question

I am new to Magento, but I thought I got to it until today. Here is my problem.

I am writing a new Observer to add a coupon to the cart when the page loads. The coupon code is passed to the URL, and I want the code to go through ANY working URL.

For example: http: // magento /? Coupon = MYCOUPON

I caught the "controller_front_init_routers" event to capture the coupon code.

I have an observer, but if I already have the goods in the basket and I pass the coupon code, then my basket seems empty, this is how I add the coupon:

    public function applyCoupon($observer){
        $coupon_code = $observer->getEvent()->getData('front')->getRequest()->getParam('coupon');
        if(!empty($coupon_code)){
            Mage::getSingleton('checkout/session')->setData('coupon_code', $coupon_code);
            Mage::getSingleton('checkout/cart')->getQuote()->setCouponCode($coupon_code)->save();

            Mage::log('Coupon Code: '. $coupon_code);
        }
    }

It seems that at any time I call Mage :: getSingleton ("checkout / session") -> anything () I am losing the session for the basket.
