切换订阅 - 直接添加到购物车

Question

我试图绕过单个产品页面，因此我为我的订阅创建了一个自定义模板页面。在此页面上，我正在生成按钮以允许用户注册特定订阅或切换他们的订阅。我遇到的问题是让 Switch 订阅 URL 转到购物车而不是单个产品页面。

下面的函数将测试用户是否登录，如果他们没有显示添加订阅到购物车的 URL。如果他们是显示我试图将其添加到购物车（或直接结帐）的切换订阅网址。

/**
 * Get Subscription URL ( Initial or Switch Subscription ) by Subscription ID
 *
 * @param Integer $subscription_id
 *
 * @return void
 */
function woo_subscriptions_checkout_url( $subscription_id, $echo = true ) {

    $subscription_id    = intval( $subscription_id );
    $subscription_url   = do_shortcode( '[add_to_cart_url id="' . $subscription_id . '"]' );

    if( is_user_logged_in() && function_exists( 'wcs_get_users_subscriptions' ) ) {

        $user_subscriptions = wcs_get_users_subscriptions();

        if( ! empty( $user_subscriptions ) ) {

            foreach( $user_subscriptions as $subscription ) {

                $subscription_order_id  = $subscription->get_parent_id();
                $subscription_key       = wcs_get_old_subscription_key( $subscription );

                if( ! empty( $subscription_key ) ) {

                    $plan_parent_id     = wp_get_post_parent_id( $subscription_id );
                    $subscription_url   = WC_Subscriptions_Switcher::add_switch_query_arg_post_link( get_permalink( wc_get_page_id( 'subscriptions' ) ), $plan_parent_id );

                    // Failed Test, Goes to Product
                    // $subscription_url    = WC_Subscriptions_Switcher::get_switch_url( $subscription_order_id, array( 'product_id' => $plan_parent_id ), $subscription );

                }

            }

        }

    }

    if( $echo ) {
        echo $subscription_url;
    } else {
        return $subscription_url;
    }

}

附加信息：有 1 个产品以订阅作为变体。我将变体 ID 传递给此函数，希望生成正确的 URL。

Answer 1

这就是我们得到的。我们可以使用特定的 URL 参数将其添加到购物车：产品、用户订阅 ID、新订阅 ID、订阅订单行号和随机数。难道我们不是在订阅作为变体的单一产品上这样做的。这可能需要在其他订阅案例中进行调整，但希望它对以后的人有所帮助：
