If you need to detect if a logged in user has purchased a certain product ID, this snippet will do the trick. You can use this for marketing (e.g. “Buy More of This!”) or for displaying special notices on the loop or the single product page. Enjoy!
PHP Snippet: Check if Logged In User Has Already Purchased a Product
Thanks to Woo (woo-hoo!) there is a handy little function called “wc_customer_bought_product”. So, no need to code that from scratch, that function already does the check for us.
