WooCommerce: Only Allow to Buy a Product Once

In the era of online courses, subscriptions, custom-made products and product personalization, it may happen a scenario where a user can only purchase a product once in their lifetime.

In this short tutorial, we will see how this is done.Clearly, the user must be logged in in order for the code to trigger, so this applies to stores that require checkout login in order to proceed with the order.

Enjoy!

User “Rodolfo Melogli” is currently logged in and in the past he purchased this same product. Result: the add to cart button is not showing thanks to the snippet below.

PHP Snippet: One Product Purchase in a Lifetime @ WooCommerce Single Product / Cart / Checkout

add_filter( 'woocommerce_is_purchasable', 'bbloomer_deny_purchase_if_already_purchased', 9999, 2 );
 
function bbloomer_deny_purchase_if_already_purchased( $is_purchasable, $product ) {
   if ( is_user_logged_in() && wc_customer_bought_product( '', get_current_user_id(), $product->get_id() ) ) {
      $is_purchasable = false;
   }
   return $is_purchasable;
}

Notes:

  • it would be nice to add a notice to tell the user why the Add to Cart is not showing. The snippet above ONLY hides the add to cart
  • in case the already purchased product is in the Cart, and user logs in from there, item will be removed from the Cart and an error message will be displayed
  • same applies to the Checkout page, in case the user logs in from there

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.

  1. I found ths a great snippet. Thanks very much for helping me understand PHP in the funtions file through code like this. Unfortunately for me, the “Product already Purchased” additional snippet causes layout problems, forcing the next item on to the next row in the catalogue layout.

    1. Thank you! For the issue, it may just need some additional CSS

  2. Thank You Rodolfo
    This is a code that I was looking for a long now, I building a coupon website for a client, but customs can get only one product/coupon
    Tell me must I replace the bbloomer_ with my website name?
    Kind Regards

    1. No need, no, that’s only a prefix I use, you can either remove it, or rename it. Basically you can give the PHP function whatever name you want

  3. What a great help! Thanks for sharing thisI would like to understand, how to make this apply only to one specific product (in my case it´s a specific Woocommerce subscription), so user can buy a specific subscription only one time AND only if he has no purchase history yet. Where can I donate etc for a profound answer? 🙂

      1. Was this answered? I could also use a single product restriction. So IF this is product A, then only buy once.

        1. I answered privately, yes. Basically, I suggest you take a look at “conditional logic”: https://businessbloomer.com/woocommerce-conditional-logic-ultimate-php-guide/. Enjoy 🙂

  4. How can I add a message like “Product already Purchased” ?

    1. You could use something along the lines of this:

      add_action( 'woocommerce_single_product_summary', 'bbloomer_message_if_not_purchasable', 29 );
      
      function bbloomer_message_if_not_purchasable() {
         global $product;
         if ( is_user_logged_in() && wc_customer_bought_product( '', get_current_user_id(), $product->get_id() ) ) {
            echo 'You already bought this product!';
         }
      }
      
      1. Hi Rodolfo

        Thank you for sharing the piece of code. Its great and wokrs perfect for me.
        But I also use the piece of code to have a message displayed instead of the add to cart button on a simple product page but the text does not appear. Can you help please?

        Thanks

        1. Hi Francois, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  5. That is good, but could be better if there is a time limit.
    Like if customer bough it in last 24 hours, then can’t buy again.
