Hello, I'm making a subscription club using WooCommerce and I'd like it possible to buy only one product at a time. I thought about maybe cleaning the cart before adding the new product or even limiting the amount of products.
Does anyone know if it's possible?
Thank you.
To clean the cart before adding a new product, you can use the following filter:
add_filter( 'woocommerce_add_cart_item_data', 'woo_custom_add_to_cart' );
function woo_custom_add_to_cart( $cart_item_data ) {
global $woocommerce;
$woocommerce->cart->empty_cart();
// Do nothing with the data and return
return $cart_item_data;
}
In that SOen thread (which was where I took the above snippet) you can follow a slightly more in-depth discussion on how to do this, as well as how to limit the number of cart items to just 1 which, in practice, is the same thing.)
