Add AffiliateWP affiliate when RCP subscription occurs (requires specifying desired RCP action, and subscription).

rcp_add_affwp_affiliate_at_rcp_sub.php

<?php

function rcp_add_affwp_affiliate_at_rcp_sub() {

    $user_info = get_userdata();
    $user_id   = $user_info->user_id;

    $member = new RCP_Member( $user_id );

    $subscription_id = $member->get_pending_subscription_id();

    if( ! $member || ! $member->ID > 0 ) {
        die( 'No member found' );
    }

    if( empty( $subscription_id ) ) {

        $subscription_id = $member->get_subscription_id();

    }

    if( ! $subscription_id ) {
        die( 'No subscription for member found' );
    }

    if( ! rcp_get_subscription_details( $subscription_id ) ) {

    // check sub id

                'status' => 'pending'
            )
        );
    } else {
        die( 'Unable to add afffiliate' );
    }



}
// You'll need to specify the desired action in RCP,
// as there isn't (that I can tell) a single
// action that fires in all cases.
//
// Another option is to use the RCP method
// $member->just_upgraded()
