Combining shopping cart when guest logs in

[mark2]

Hi,

If a user:

logs in, adds some items to their shopping cart, logs out. Then as a guest adds items to a shopping cart, then logs in.

The first shopping cart is lost. I wanted the two carts to be combined. It seems this can be done in the authentication.php file:

            
if (Configuration::get('PS_CART_FOLLOWING')){
 if (empty($cookie->id_cart) OR Cart::getNbProducts($cookie->id_cart) == 0) {
   $cookie->id_cart = intval(Cart::lastNoneOrderedCart(intval($customer->id)));
 } else {
   // Combine orders
   $lastCartID = Cart::lastNoneOrderedCart(intval($customer->id));
   if (Cart::getNbProducts($cookie->id_cart) > 0 && $lastCartID) {
      $last_cart = new Cart($lastCartID);
      if (!Validate::isLoadedObject($last_cart)) {
        $products = $cart->getProducts();
        foreach ($products as $p) {
          $last_cart->updateQty($p['cart_quantity'], $p['id_product']);
        }
        $last_cart->update();
        $cart->delete();
        $cart = $last_cart;
        $cookie->id_cart = $cart->id;
      }
    }
 }
}

This might be of use to someone. Or you might see a problem with this, in which case your comments would be of use to me.

Regards,
Mark

Hi, the code did not work for customized products but seemed OK otherwise. I'm using 1.2.5 so the code may not work on any other version. I hacked something together to deal with customized products you can PM me about that.
