Question

我正在尝试绕过单个产品页面，因此我为订阅创建了自定义模板页面。在这个页面上，我正在生成按钮，允许用户注册特定订阅或切换订阅。我遇到的问题是将Switch订阅URL转到购物车而不是单个产品页面。

以下功能将测试用户是否已登录，如果他们显示购物车网址的添加订阅。如果他们显示我正在尝试将其添加到购物车的交换机订阅网址（或直接结帐）。

/**
 * 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;
    }

}

其他信息：有1个产品的订阅作为变体。我正在将Variation 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中：产品，用户订阅ID，新订阅ID，订阅订单行号和随机数。难道我们不对具有订阅版本的单个产品执行此操作。在其他订阅情况下，可能需要对此进行调整，但希望它对以后的工作有所帮助：
