Magento Select Items from cart before place order

Question

I am trying to implement a module in Magento 1.9. And i want to enable the customer to select a specific items or all items from cart before place the order. For example customer add the item A, and item B in the cart. Then during checkout at first step he will decide for which items he want to place order

Option 1: Item A only. After place the order Item B will remain in cart

Option 2: Item B only. After place the order Item A will remain in cart

Option 3: Item A and B. After place the order cart will be empty.

Can you please let me know any idea how can i achieve the above explained functionality? Thank you very much.

Answer 1

Magento have the wish-list concept. You can use that for this functionality.

Initially you can use wish-list instead of cart and then at the time of place order you can give the selection to user which item they have to place order.

That item you can move in cart and checkout, rest will be there in wish-list.

If you don't want to show wish-list then you can rename it and use as a cart.

Answer 2

I think that what you're asking is (close to) impossible. At the end of the checkout, Magento will convert the quote into an order. The quote contains all products that are in your cart, along with other stuff like totals, shipping costs, etc. So having items in your cart that need to remain in the cart, while others are converted to order items. That would at least take some heavy modifications in the checkout logic in Magento.

Therefor I'd go for the wishlist, that's also said by Ashish. When you add a product to your cart, the shopping cart promotion rules will be applied to the quote. But only for as long as those rules are active. After that, when you review the cart, the rules will be disabled/removed for the quote as well. And when you add a product to the cart at a later moment (from the wishlist), the rules will still be applied.

Answer 3

We can achieve it using the two carts for one customer at the same time. When customer will choose the items then remaining items move to the temporary cart. And after place the order or for edit the selected items we can get the un-selected items from the temporary cart against the customer. I have implemented it using the described way. I hope it will help some one else.
