Woocommerce:整个产品类别的最低数量，而不是变化

Question

因此，我已经安装了一个插件(“高级产品数量”)，它允许我为类别和产品设置最小数量。然而，我要做的是为整个产品/类别设定一个最小的数量，而不是为每个单独的变化设置最小的数量。为了更好地理解这一点，我有一家烘焙食品公司，在那里我出售百吉饼。顾客至少需要订购12个百吉饼。他们可以订购他们想要的任何种类的百吉饼(例如:4个罂粟籽，5个普通面包，3个洋葱等)，只要他们至少订购12个百吉饼。

当我为百吉饼类设定一个最小类别时，它会使购物车中的每种产品都增加到12种来完成结账，而不是认识到它们都是一种百吉饼，因此满足了整个百吉饼最少12个百吉饼的要求。

有没有人知道我怎样才能让这个最小数量的概念适用于我的情况？

试试下面的代码：

    // 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' );
            }

        }

    }

编辑：

    // 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 ( has_term( 'bagels', 'product_cat', $product['product_id'] ) ) :
                    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' );
                    }
                endif;

            }

        }
