用购物车总数和订购期替换WooCommerce“下单”按钮文本

Question

我使用以下代码专门针对基于订阅的产品。

// Display total amount on place order button
add_filter('woocommerce_order_button_text', 'subscriptions_custom_checkout_submit_button_text' );
function subscriptions_custom_checkout_submit_button_text( $order_button_text ) {
if ( WC_Subscriptions_Cart::cart_contains_subscription() ) {
    $cart_total = WC()->cart->total;    
return __('Pay $' . $cart_total, 'woocommerce');
    
} else {
    // You can change it here for other products types in cart
    # $order_button_text =  __( 'Something here', 'woocommerce-subscriptions'  );
}
return $order_button_text;
}

现在，我希望在产品价格之后显示订阅期限，例如，如果有人购买每月订阅的产品，按钮应该显示为(Pay $20/Month)。

当购物车中只有订阅产品时，您可以通过以下方式在结账页面获得自定义的“下单”按钮，并在提交按钮上显示购物车合计和订阅期限：

add_filter('woocommerce_order_button_text', 'subscriptions_custom_checkout_submit_button_text' );
function subscriptions_custom_checkout_submit_button_text( $button_text ) {
    if ( WC_Subscriptions_Cart::cart_contains_subscription() ) {
        $cart  = WC()->cart;
        $total = $cart->total;
        $other = false;

        // Loop through cart items
        foreach ( $cart->get_cart() as $item )  {
            $product = $item['data'];
            if( in_array( $product->get_type(), ['subscription', 'subscription_variation'] ) ) {
                $period = get_post_meta( $product->get_id(), '_subscription_period', true );
            } else {
                $other = true; // There are other items in cart
            }
        }
        // When there are only Subscriptions in cart
        if ( isset($period) && ! $other ) {
            return sprintf( __('Pay %s/%s' , 'woocommerce'), strip_tags( wc_price($total) ), ucfirst($period) );
        }
    }
    return $button_text;
}

代码放在活动子主题(或活动主题)的functions.php文件中。经过测试，效果良好。
