How WooCommerce Coupons are stored in Database?

Question

I need to run a script to check my coupons every time I have a new register, but I can't find where the coupons from coupon generator (WooCommerce) are stored.

Solution

WooCommerce Coupon are stored in wp_posts table with post_type => 'shop_coupon'. And all the associated data are stored in wp_postmeta table.

You can use this MySQL query to get all the Coupon:

SELECT * FROM `wp_posts` WHERE `post_type` = 'shop_coupon' ORDER BY `ID` DESC

And this gets all coupons

SELECT p.`ID`, 
       p.`post_title`   AS coupon_code, 
       p.`post_excerpt` AS coupon_description, 
       Max(CASE WHEN pm.meta_key = 'discount_type'      AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS discount_type,          -- Discount type 
       Max(CASE WHEN pm.meta_key = 'coupon_amount'      AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS coupon_amount,          -- Coupon amount 
       Max(CASE WHEN pm.meta_key = 'free_shipping'      AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS free_shipping,          -- Allow free shipping 
       Max(CASE WHEN pm.meta_key = 'expiry_date'        AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS expiry_date,                -- Coupon expiry date 
       Max(CASE WHEN pm.meta_key = 'minimum_amount'     AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS minimum_amount,         -- Minimum spend 
       Max(CASE WHEN pm.meta_key = 'maximum_amount'     AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS maximum_amount,         -- Maximum spend 
       Max(CASE WHEN pm.meta_key = 'individual_use'     AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS individual_use,         -- Individual use only 
       Max(CASE WHEN pm.meta_key = 'exclude_sale_items' AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS exclude_sale_items,         -- Exclude sale items 
       Max(CASE WHEN pm.meta_key = 'product_ids'    AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS product_ids,                -- Products 
       Max(CASE WHEN pm.meta_key = 'exclude_product_ids'AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS exclude_product_ids,        -- Exclude products 
       Max(CASE WHEN pm.meta_key = 'product_categories' AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS product_categories,             -- Product categories 
       Max(CASE WHEN pm.meta_key = 'exclude_product_categories' AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS exclude_product_categories,-- Exclude Product categories 
       Max(CASE WHEN pm.meta_key = 'customer_email'     AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS customer_email,         -- Email restrictions 
       Max(CASE WHEN pm.meta_key = 'usage_limit'    AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS usage_limit,                -- Usage limit per coupon 
       Max(CASE WHEN pm.meta_key = 'usage_limit_per_user'   AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS usage_limit_per_user,   -- Usage limit per user 
       Max(CASE WHEN pm.meta_key = 'usage_count'    AND  p.`ID` = pm.`post_id` THEN pm.`meta_value` END) AS total_usaged                   -- Usage count 
FROM   `wp_posts` AS p 
       INNER JOIN `wp_postmeta` AS pm ON  p.`ID` = pm.`post_id` 
WHERE  p.`post_type` = 'shop_coupon' 
       AND p.`post_status` = 'publish' 
GROUP  BY p.`ID` 
ORDER  BY p.`ID` ASC;

Any idea where the expiry date might be?

[Raunak Gupta]

@DeepakShenoy: expiry date is stored in wp_postmeta table against the post_id and meta_key = expiry_date. Please check the reference link attached with the answer.

Hi, sorry for duplicate comment, left one on your website. Is it possible to retrieve order meta of the user that used the coupon? My coupon usage limit is set to 1, for all coupons. I would like ti include in the report the user's name, email address and possibly some other custom fields. Thank you.
