Magento – Remove item from cart

cartcheckoutquote

To give a little context, we are using the OrganicInternet Simple Configurable Products module to avoid having configurable products in our cart. All simple products on the site are marked as not visible individually. The problem we have is that a simple product remains in the cart even when it's associated configurable is disabled or removed.

The quote_item for the simple product contains the ID of the configurable product that was added, so the obvious solution to this seems to be to hook into an event use the cpid to check if the configurable product is enabled and remove the item from the quote.

The only problem is, I'm not entirely sure where to hook into. I tried _before_save on the quote, this seems to work, but has the issue that if no items are left in the quote, you end up seeing an empty basket (as opposed to the empty basket message). Any suggestions?

Best Answer

In the end the best option seems to be creating an event listener for sales_quote_item_collection_products_after_load to remove the products from the collection. This in turn causes the quote item to be marked for deletion, which in turn updates the database when the quote is saved. As far as I can tell this is how a quote item is removed when a product is disabled.

Magento – Change Price of configurable quote item with observer

I figured it out myself. You need to observe the event checkout_cart_product_add_after. In the observer you need the following:

public function change_price(Varient_Event_Observer $observer) {
    // get the quote
    $item = $observer->getQuoteItem();

    // checks for parent item
    if ($item->getParentItem()) {
        $item = $item->getParentItem();
    }

    // your price logic here
    $new_price = 999;

    $item->setCustomPrice($new_price);
    $item->setOriginalCustomPrice($new_price);
    $item->getProduct()->setIsSuperMode(true);
}
