WooCommerce: Finding the products in database

I'm creating a website using WooCommerce and I want to restrict the available products to users depending on the postcode that they enter in the search form on my home page.

To be able to achieve that I'll have to specify the conditions of each product within the database in phpMyAdmin, but I can't seem to find it.

Does anybody know where the woocommerce database for products and/or categories are within phpmyAdmin?

Thank you in advance.

Update 2020

Products are located mainly in the following tables:

• wp_posts table with post_type like product (or product_variation),

• wp_postmeta table with post_id as relational index (the product ID).

• wp_wc_product_meta_lookup table with product_id as relational index (the post ID) | Allow fast queries on specific product data (since WooCommerce 3.7)

• wp_wc_order_product_lookuptable with product_id as relational index (the post ID) | Allow fast queries to retrieve products on orders (since WooCommerce 3.7)

Product types, categories, subcategories, tags, attributes and all other custom taxonomies are located in the following tables:

• wp_terms

• wp_termmeta

• wp_term_taxonomy

• wp_term_relationships - column object_id as relational index (the product ID)

• wp_woocommerce_termmeta

• wp_woocommerce_attribute_taxonomies (for product attributes only)

• wp_wc_category_lookup (for product categories hierarchy only since WooCommerce 3.7)

---

Product types are handled by custom taxonomy product_type with the following default terms:

• simple
• grouped
• variable
• external

Some other product types for Subscriptions and Bookings plugins:

• subscription
• variable-subscription
• booking

---

Since Woocommerce 3+ a new custom taxonomy named product_visibility handle:

• The product visibility with the terms exclude-from-search and exclude-from-catalog
• The feature products with the term featured
• The stock status with the term outofstock
• The rating system with terms from rated-1 to rated-5

Particular feature: Each product attribute is a custom taxonomy…

• Specific tables: Woocommerce database description

The following tables are store WooCommerce products database :

• wp_posts -

The core of the WordPress data is the posts. It is stored a post_type like product or variable_product.

• wp_postmeta-

Each post features information called the meta data and it is stored in the wp_postmeta. Some plugins may add their own information to this table like WooCommerce plugin store product_id of product in wp_postmeta table.

Product categories, subcategories stored in this table :

• wp_terms
• wp_termmeta
• wp_term_taxonomy
• wp_term_relationships
• wp_woocommerce_termmeta

following Query Return a list of product categories

SELECT wp_terms.* 
	FROM wp_terms 
	LEFT JOIN wp_term_taxonomy ON wp_terms.term_id = wp_term_taxonomy.term_id
	WHERE wp_term_taxonomy.taxonomy = 'product_cat';

Bulk add new categories to Woo:

Insert category id, name, url key

INSERT INTO wp_terms 
VALUES
  (57, 'Apples', 'fruit-apples', '0'),
  (58, 'Bananas', 'fruit-bananas', '0');

Set the term values as catergories

INSERT INTO wp_term_taxonomy 
VALUES
  (57, 57, 'product_cat', '', 17, 0),
  (58, 58, 'product_cat', '', 17, 0)

17 - is parent category, if there is one

key here is to make sure the wp_term_taxonomy table term_taxonomy_id, term_id are equal to wp_term table's term_id

After doing the steps above go to wordpress admin and save any existing category. This will update the DB to include your bulk added categories

I would recommend using WordPress custom fields to store eligible postcodes for each product. add_post_meta() and update_post_meta are what you're looking for. It's not recommended to alter the default WordPress table structure. All postmetas are inserted in wp_postmeta table. You can find the corresponding products within wp_posts table.

get product category IDs by providing product_id (wp_posts ID column):

SELECT
	term_taxonomy_id
FROM
	wp_term_relationships
WHERE
	object_id = PRODUCT_ID_HERE
	AND
	term_taxonomy_id IN
		(
			SELECT
				term_taxonomy_id
			FROM
				wp_term_taxonomy
			WHERE
				taxonomy LIKE 'product_cat'
		)

get category data (name, slug) and category hierarchical structure:

SELECT
	wp_terms.term_id,
	wp_terms.name,
	wp_terms.slug,
	wp_term_taxonomy.parent
FROM
	wp_terms
LEFT JOIN
	wp_term_taxonomy
	ON wp_terms.term_id = wp_term_taxonomy.term_id
WHERE
	wp_term_taxonomy.taxonomy LIKE 'product_cat'
