This approach might be relevant for specific promotional offers (e.g. BOGO) or custom coded product bundles. In this case, you may want to remove a second item from the cart – programmatically – once a product is removed.
Of course, a relationship is needed between the two cart items via custom cart item meta data (for example, the “bundled” item will need to specify the ID of the “base” product in the cart within some custom cart item meta, so that we can “listen” to its removal).
Alternatively, you can check if a pair of product IDs are in the cart, and if one of them is removed, we’ll automatically remove the other – this is the case study we’ll go through today as it’s much easier.
Enjoy!
