How to delete all shopping cart items of all customers in Magento?

Question

I want to delete all shopping cart items (products added to cart) of all customers in Magento.

How can I do that?

In detail :-

Suppose, I have total 10 registered customers in my shop. They might have items (products) added to cart. I want to clear all items added to cart for all the 10 registered customers.

Answer 1

My first guess would be something like,

$items = Mage::getResourceModel('sales/quote_item_collection');

foreach ($items as $item) {
    $item->delete();
}

The cart items are stored as part of a 'quote'. Looping through them all like this might be slow, doing it in SQL is quicker but not as safe.

TRUNCATE `sales_flat_quote_item`;

Answer 2

I know, it's not related directly your question but might be help.

Inchoo has published an article a few days ago which is putting "Cart Empty" link on cart page.

There's no “EMPTY CART” on Magento's cart page
