how to get third table count with group concat

Question

I have a three tables.
1) tbl_product base table //which stores the product information.

id int(11) unsigned
product_type_id int(11) unsigned
product_image   varchar(255)
title   varchar(255)
description text
price   float(8,2)
discount_price  float(8,2)
status  tinyint(1)
created_at  datetime
updated_at  datetime

2) tbl_product_review //which stores the reviews of every product.

id  int(10) unsigned
product_id  int(10) unsigned
title   varchar(255)
description text
star_rating int(1)
status  int(1)
created_at  int(10)

3) tbl_wishlist //which store the user's wishlist details means when user add any product into his/her wishlist that entry saved in this table

id  int(11) unsigned
product_id  int(11) unsigned
user_id int(11) unsigned
status  tinyint(1) unsigned
created_at  datetime

These are my table architecture. I want fetch user's id using group concat according to product id. means if product id is 1 then all the user's id just come up with (1,3,4,5) like this. next is, I want total number of product reviews of each product. for eg if user id is 1 then product number comes with 1 or 0 if have or don't have.

Actually i want this type of output

id  product_type_id title               description              price  discount_price       product_image      users   total_review
1   1               Product one         Product one description  786       50               product.jpg        1,2         2

I want do this by a single query.I don't want to fetch first half information after that start loop after than get next half information. I think you understand my problem.

You can try like below. You can get the concated user list and count from respective table and then can JOIN them with base product table to get the consolidated result.

select p.*,XX.total_review,XXX.user_list
from tbl_product p join (

select product_id, count(*) as total_review
from tbl_product_review
grup by product_id
) XX on product_id = XX.product_id
join (
select product_id,group_concat(user_id) as user_list
from  tbl_wishlist
group by product_id
) XXX on p.product_id = XXX.product_id
