Getting count from inner join table - php

Question

I have tables as described below:
subscription_plans (Table for storing all plans)
id plan days_limit added_on status rate
------------------------------------------------
1 PlanA 15 1398249706 1 150.00
2 PlanB 15 1398249706 1 150.00
subscribed_videos (Table for storing details of video in each plans)
id plan_id videoid
----------------------
1 1 1
2 2 2
subscription_groups (Table for storing groups where a plan can be part of another plan. ie, Plan A be a plan with 2 other individual plans, Plan B and C )
id plan_id assosiated_plan_id added_on
----------------------------------------------
1 1 2 1398249706
usersubscription (Table for storing user subscribed plans)
id user_id plan_id subscribed_on
---------------------------------------
1 1 1 1398771106
Now, my problem is that how can I get the count of videos for each plans. If Plan A contains both Plan B and C (subscription_groups table), then the count should return the total video count for each individual plans in that particular plan. Now I have done with a query which will return plan details along with count of videos for a plan but I am not able to join it with subscription_groups. How can I accomplish this in a single query.
$data['planquery']=$this->db->query("select
us.plan_id,us.subscribed_on,sp.plan,sp.days_limit,sp.rate,count(sv.videoid) from
usersubscription as us INNER JOIN
subscription_plans as sp ON us.plan_id=sp.id INNER JOIN subscribed_videos as sv ON sp.id=sv.plan_id where sp.status=1 and us.user_id=1");
Expected Result:
plan_id subscribed_on plan days_limit rate count
-------------------------------------------------------
1 1398771106 PlanA 15 150.00 2
Can anyone help me to find a solution for this?
Thanks in advance.

You can do so
SELECT
us.plan_id,
us.subscribed_on,
sp.plan,
sp.days_limit,
sp.rate,
COUNT(sv.videoid)
FROM
usersubscription AS us
RIGHT JOIN subscription_plans AS sp
ON us.plan_id = sp.id
INNER JOIN subscribed_videos AS sv
ON sp.id = sv.plan_id
INNER JOIN subscription_groups g
ON(g.plan_id =sv .plan_id OR sv.plan_id= g.assosiated_plan_id)
WHERE sp.status = 1
AND (us.user_id = 1 OR us.user_id IS NULL )
Demo
Since user has only plan associated but the associated plan can also has another plan linked so the last condition will check the user id but for is null to for the second linked plan user id will be null due to right join on subscription_plans
Edit
SELECT
u.plan_id,
u.subscribed_on,
p.plan,
p.days_limit,
p.rate
,COUNT(DISTINCT v.`videoid`)
FROM `usersubscription` u
JOIN `subscription_groups` g
ON (u.`plan_id` = g.`plan_id`)
RIGHT JOIN `subscription_plans` p
ON(u.`plan_id` = p.`id` OR g.`assosiated_plan_id` = p.`id`)
INNER JOIN `subscribed_videos` v ON(v.`plan_id`=g.`assosiated_plan_id` OR u.`plan_id`= v.`plan_id`)
WHERE u.`id`=1 AND p.`status` = 1

For video ids you can use group_concat
SELECT
u.plan_id,
u.subscribed_on,
p.plan,
p.days_limit,
p.rate
,COUNT(DISTINCT v.`videoid`) `video_count` ,
GROUP_CONCAT(DISTINCT v.`videoid`) `video_ids`
FROM `usersubscription` u
JOIN `subscription_groups` g
ON (u.`plan_id` = g.`plan_id`)
RIGHT JOIN `subscription_plans` p
ON(u.`plan_id` = p.`id` OR g.`assosiated_plan_id` = p.`id`)
INNER JOIN `subscribed_videos` v ON(v.`plan_id`=g.`assosiated_plan_id` OR u.`plan_id`= v.`plan_id`)
WHERE u.`id`=1 AND p.`status` = 1
