I have one table with following fields...
id category_id product_id
1 1 1001
2 2 1001
3 1 1003
4 4 1001
5 1 1005
Now i'm trying to fetch out product id using category id.
So suppose in my query string i pass www.demo.com/?category=1,2,4
I want to get product which match in all value(1,2,4). so in this case it should return me only 1001.
How can i achieve this?
