Woocommerce - limit a product to only be purchased once per user

Envato Customers Web and Code

Hi there,

Does anyone know how I can limit a product to only be purchased once per user account? Is there any plugin I can use to achieve this?

My site is all digital downloads and it has a chart for sales, I need this function to stop people purchasing the product many times to effect the charts.

Many thanks in advance

I don’t know of any through CodeCanyon sadly. Most plugins like this are one time limitations, meaning they only check the cart, not a user’s history. I had to use one once and I found it through PNW Design. I don’t think I can include links, but if you do a google search you should be able to find some ranging from reasonable to quite expensive.

There is a notification plugin through CodeCanyon that tells the customer they have already purchased the item, but I don’t think it will prevent them from doing it again.

Thanks bolderelements :slight_smile: I did already try PNWs plugin, brought it yesterday, but it doesn’t work for me for some frustrating reason!.

You can try to achive this by hire a freelancer to do, here’s my opinion:

  • When user check out > write the user ID into a custom field for that product > save

  • When user try to “add_to_cart”, we will perform an action, check if the user id is in the field we wrote > true > show notice bought cant bought again, else put it on the user’s cart.

It’s pretty simple though, you can hire someone on Upwork for that.

I would do something similar, but I would not pollute the post meta for that. It’s already possible to find out which products a user bought by querying the orders. Also, no need to wait until a customer adds the product to the cart, such operation can be prevented altogether.

// Disable repeat purchase of products / variations
function sv_disable_repeat_purchase( $purchasable, $product ) {

// Don't run on parents of variations,
// this will already check variations separately
if ( $product->is_type( 'variable' ) ) {
    return $purchasable;
}

// Get the ID for the current product (passed in)
$product_id = $product->is_type( 'variation' ) ? $product->variation_id : $product->id; 

// return false if the customer has bought the product / variation
if ( wc_customer_bought_product( wp_get_current_user()->user_email, get_current_user_id(), $product_id ) ) {
    $purchasable = false;
}

// Double-check for variations: if parent is not purchasable, then variation is not
if ( $purchasable && $product->is_type( 'variation' ) ) {
        $purchasable = $product->parent->is_purchasable();
}

return $purchasable;
