Woocommerce: Minimum Quantity for Overall Product Category, not variations

2 Views

So, I already have a plugin (“Advanced Product Quantities”) installed that allows me to set minimum quantities for categories and products. However, what I’m trying to do is set a minimum quantity for an overall product/category rather than a minimum for each of its individual variations. To put this into context, I have a baked goods business where I sell bagels. A customer needs to order a minimum of 12 bagels. They can order however many bagels of each kind that they want (for ex: 4 poppy seed, 5 plain, 3 onion, etc.), so long as they order a minimum of 12 bagels total.

When I set a category minimum for the bagel category, it makes each product variation in the shopping cart increase its quantity to 12 to fulfill checkout, rather than recognize that they are all a type of bagel and therefore fulfill the overall bagel minimum of 12 bagels.

Does anyone have any ideas on how I can get this minimum quantity concept working for my situation?

  1. Try out this code: 

        // Set minimum quantity per product before checking out
    add_action( 'woocommerce_check_cart_items', 'rohil_set_min_total' );
    function rohil_set_min_total() {
        // Only run in the Cart or Checkout pages
        if( is_cart() || is_checkout() ) {

            global $woocommerce, $product;
            $i=0;
            //loop through all cart products
            foreach ( $woocommerce->cart->cart_contents as $product ) :


                // Set minimum product cart total
                $minimum_cart_product_total = 12;

                // See if any product is from the bagel category or not
                if ( has_term( 'bagels', 'product_cat', $product['product_id'] ) ) :

                    $total_quantity += $product['quantity'];

                endif;

            endforeach;

            if( $total_quantity < $minimum_cart_product_total ) {
                // Display our error message
                wc_add_notice( sprintf( '<strong>A Minimum of %s products is required from bagel category before checking out.</strong>'
                    . '<br />Current number of items in the cart: %s.',
                    $minimum_cart_product_total,
                    $total_quantity ),
                'error' );
            }

        }

    }

    EDITED:
