Zend Framework SpeckCart not working correctly

Question

I am using SpeckCart shopping cart module in my ZF2 project. I have setup the module and it adds item to the cart successfully, but it overwrites the same item on every call instead of adding new items. Please guide me where I am doing anything wrong, here is the code:

    public function addAction(){
    $prod_id = $this->params()->fromPost('prod_id');
    $product = $this->getProductTable()->getProduct($prod_id);

    $item = new CartItem();
    $item->setDescription($product->name);
    $item->setCartItemId($prod_id);
    $item->setPrice($product->price);

    $cs = $this->getServiceLocator()->get('SpeckCart\Service\CartService');

    $cart = $cs->getSessionCart(true); 

// I think the above line is creating a new cart every time and this is where the problem lies. I am unable to know how to make it use the existing cart created in previous call.

    $cs->addItemToCart($item, $cart);

I am a newbie regarding ZF, please let me know how should I use this cart module properly. The above code is from an action of my application that is called every time the 'add to cart' button is pressed.

Just came across this after trying the speckcart module out for the first time. I think your problem here is that you are trying to set the CartItemId. The database code (provided within the module) makes the cart item Id an auto-incremented primary key field, which therefore should not be set as the database should create it automatically.

Also, you must supply a quantity as the quantity's database field is set to not accept null values.

Other than that, everything should work.

Hope this helps.
