WooCommerce: Hide Add to Cart If Already Purchased

We already saw how to hide add to cart for logged out users and how to find out if a user has already bought a given product – so I said why not combine the two snippets and figure out how to hide the add to cart button if a logged in customer has already purchased a product?

After that, however, I realized that the “woocommerce_is_purchasable” filter offered by the WooCommerce plugin makes the task much easier than just combining the two mini-plugins above.

So, here’s how it’s done – enjoy!

PHP Snippet: Deny Further Sales If User Has Already Purchased a Product @ Shop / Single Product Page

This snippet will:

1. Hide the Add to Cart completely on the single product page
2. Rename the Add to Cart on the Shop Page to “Read More”
3. Make it impossible to add the item to cart even with an URL – it will show a red “Sorry, this product cannot be purchased.” error in such case
