Woocommerce 按类别/数量的最小订单

Question

我想知道是否可以创建一个 if 语句，如果客户没有在他们的订单中添加足够的特定产品类别（数量而不是价格），则会显示一条消息说他们需要添加更多以避免附加费。我正在考虑最小订单量 sn-p documented here:

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
    function wc_minimum_order_amount() {
        global $woocommerce;
        $minimum = 50;
    if ( $woocommerce->cart->total() < $minimum ) {
        $woocommerce->add_error( sprintf( 'You must have an order with a minimum of %s to place your order.' , $minimum ) );
    }
}

任何帮助将不胜感激。

Answer 1

来自WooCommerce Docs

public float $cart_contents_count - 购物车商品的总数。

因此，这应该可以满足您的需求：

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
function wc_minimum_order_amount() {
    global $woocommerce;
    $minimum = 50;
    if ( $woocommerce->cart->cart_contents_count < $minimum ) {
        $woocommerce->add_error( sprintf( 'You must have an order with a minimum of %s to place your order.' , $minimum ) );
    }
}

这可以通过使用woocommerce_checkout_process 和woocommerce_before_cart Woocommerce Hooks 来完成。

所以在您的主题的functions.php file 中添加此代码（更改Name Your category 字符串）：

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );

function wc_minimum_order_amount() {

    $minimum = 50; //Qty product

    if ( WC()->cart->cart_contents_count < $minimum ) {

        $draught_links = array();

        foreach(WC()->cart->get_cart() as $cart_item_key => $values ) {

            $_product = $values['data'];

            $terms = get_the_terms( $_product->id, 'product_cat' );

            foreach ($terms as $term) {
                $draught_links[] = $term->name;
            }   

        }

        if (in_array("Name Your category", $draught_links)){
            $on_draught = true;
        }else{
            $on_draught = false;
        }

        if( is_cart() ) {

            if($on_draught){

                wc_print_notice( 
                    sprintf( 'You must have an order with a minimum of %s to place your order, your current order total is %s.' , 
                         $minimum , 
                         WC()->cart->cart_contents_count
                    ), 'error' 
                );

            }

        } else {

            if($on_draught){

                wc_add_notice( 
                    sprintf( 'You must have an order with a minimum of %s to place your order, your current order total is %s.' , 
                        $minimum , 
                        WC()->cart->cart_contents_count
                    ), 'error' 
                );

            }

        }
    }

}
