php - 使用过滤器或 Hook 修改购物车总金额

好的，所以我试图编写一个过滤器或 Hook ，该过滤器或 Hook 将根据购物车中商品的总数量来修改购物车的总金额。例如，如果购物车中有三个项目，我想从总订单中扣除20美元。以下是我到目前为止的代码，非常感谢您的帮助!

add_filter('woocommerce_cart_contents_total', 'bundle_deals');

function bundle_deals( $cart_contents_total, $cart_contents_count) {
   global $woocommerce;

   if ($woocommerce->cart->get_cart()->cart_contents_count <= 3) {
     $cart_contents_total = $woocommerce->cart->get_cart()->cart_contents_total - 20.00;
   }

   return $cart_contents_total;
}

最佳答案

function woocommerce_cart_subtotal(  $cart_subtotal, $compound, $obj  ){

$t = 0;
foreach ( $obj->cart_contents as $key => $product ) :

    $product_price = $product['line_total'];

    foreach ( WC()->cart->get_coupons( 'order' ) as $code => $coupon ) :

            $product_price  = 19;//wpq_9522_discount( $product['line_total'], $coupon->discount_type, $coupon->amount );

    endforeach;

    $t += $product_price;

endforeach;

return $cart_subtotal;//( $t > 0 ) ? sprintf( '<s>%s</s> %s',
$cart_subtotal, wc_price( $t ) ) : $cart_subtotal ;
}

add_filter( 'woocommerce_cart_subtotal', 'woocommerce_cart_subtotal',      99, 3 );
