I'm trying to bypass the single product page so I've created a custom template page for my subscriptions. On this page I'm generating the buttons to either allow users to signup for a specific subscription or switch their subscription. The problem I'm running into is getting the Switch Subscription URL to go to cart instead of the single product page.

The function below will test whether the user is logged in, if they are not show the add subscription to cart URL. If they are show the switch subscription url which I'm trying to just add it to cart ( or go straight to checkout ).

/**
 * 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;
    }

}

Additional information: There is 1 product with subscriptions as variations. I'm passing the Variation ID to this function in hopes of generating the correct URL.

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，但希望它对未来的人有所帮助：

/**
 * Generate cart button based on subscription variation ID

 */
function prefix_subscriptions_checkout_button( $args = array() ) {

    $button_arr = wp_parse_args( $args, array(
        'variation_id'  => 0,
        'btn_class'     => array( 'button', 'button-primary' ),
        'btn_text'      => __( 'Sign Up' ),
        'btn_atts'      => array(),
    ) );

    $button_arr['btn_url'] = do_shortcode( '[add_to_cart_url id="' . intval( $button_arr['variation_id'] ) . '"]' );

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

        // Grab an array of user subscriptions
        $user_subscriptions = wcs_get_users_subscriptions();

        if( ! empty( $user_subscriptions ) ) {

            // Array( 'Subscription ID' => WC_Subscriptions Object );
            foreach( $user_subscriptions as $user_subscription_id => $subscription ) {

                // Loop through the users subscription order items to get the subscription order line item
                foreach( $subscription->get_items() as $item_line_number => $item_arr ) {

                    if( $user_subscription_id == $item_arr['order_id'] ) {

                        if( $item_arr['variation_id'] == $button_arr['variation_id'] ) {

                            // Change button based on status
