You'll need to apply an Advanced Filter to your userlist to filter it to active or inactive subscribers for example. The below example should get you started for showing either active or expired.
Active
Code:
( ( SELECT COUNT(*) FROM `#__cbsubs_subscriptions` AS sub WHERE sub.`user_id` = u.`id` AND sub.`status` = 'A' ) >= 1 )
Expired
Code:
( ( SELECT COUNT(*) FROM `#__cbsubs_subscriptions` AS sub WHERE sub.`user_id` = u.`id` AND sub.`status` = 'X' ) >= 1 )
This isn't filtered to a specific plan. If you only want to show from a specific plan you'd use the below for example.
Active
Code:
( ( SELECT COUNT(*) FROM `#__cbsubs_subscriptions` AS sub WHERE sub.`user_id` = u.`id` AND sub.`status` = 'A' AND sub.`plan_id` = PLAN_ID_HERE ) >= 1 )
Expired
Code:
( ( SELECT COUNT(*) FROM `#__cbsubs_subscriptions` AS sub WHERE sub.`user_id` = u.`id` AND sub.`status` = 'X' AND sub.`plan_id` = PLAN_ID_HERE ) >= 1 )
Be sure to replace PLAN_ID_HERE with your actual plan id.
