I want to fetch all category, sub-category, sub-sub-category from category table with respect of company_id. I am confused how do this. can i create a new table for store company category?

I want to display output in drop-down. I have three drop-down one is main category dropdown, second is sub-category drop-down and third is sub-sub-category drop-down. Drop-down is fill companies wise i.e different company has different category.

Output display screen.

This is my output display category

Sorry for my English.

Thanks for helping me.

Best How To :

Try this code.

  SELECT c1.`category_name` as `category` , c2.`category_name` as `sub-category`, c3.`category_name` as `sub-sub-category` FROM `categories` as c1
    LEFT JOIN `categories` as c2 ON c1.`category_id`=c2.`parent_category_id`
    LEFT JOIN `categories` as c3 ON c2.`category_id`=c3.`parent_category_id`
    where c1.`parent_category_id` IS NULL

With respect of company_id

SELECT cm.`company_id`, c1.`category_name` as `category` , c2.`category_name` as `sub-category`, c3.`category_name` as `sub-sub-category` FROM `categories` as c1
LEFT JOIN `categories` as c2 ON c1.`category_id`=c2.`parent_category_id`
LEFT JOIN `categories` as c3 ON c2.`category_id`=c3.`parent_category_id`
INNER JOIN `company_category_mapping` as cm ON cm.`category_id`=c3.`category_id`
    where c1.`parent_category_id` IS NULL

If you need to get data for specific company_id.

Ex : company_id =7

SELECT cm.`company_id`, c1.`category_name` as `category` , c2.`category_name` as `sub-category`, c3.`category_name` as `sub-sub-category` FROM `categories` as c1
    LEFT JOIN `categories` as c2 ON c1.`category_id`=c2.`parent_category_id`
    LEFT JOIN `categories` as c3 ON c2.`category_id`=c3.`parent_category_id`
    INNER JOIN `company_category_mapping` as cm ON cm.`category_id`=c3.`category_id` AND cm.`company_id`=7
        where c1.`parent_category_id` IS NULL
