Allow specific products to be only purchased once by user in Woocommerce

The following code for Woocommerce, allows being purchased again once purchased 

function sv_disable_repeat_purchase( $purchasable, $product ) {
    // Enter the ID of the product that shouldn't be purchased again
    $non_purchasable = 40021;

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

    // Bail unless the ID is equal to our desired non-purchasable product
    if ( $non_purchasable != $product_id ) {
        return $purchasable;
    }

    // return false if the customer has bought the product
    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;
}
add_filter( 'woocommerce_variation_is_purchasable', 'sv_disable_repeat_purchase', 10, 2 );

Update (removed outdated unneeded $product->variation_id …)

You can simply use the PHP conditional function in_array()… Also, your code is outdated:

  • This is outdated $product->variation_id
  • replace $product->id by $product->get_id()

Here is a simplified revisited code version:

add_filter( 'woocommerce_variation_is_purchasable', 'products_purchasable_once', 10, 2 );
add_filter( 'woocommerce_is_purchasable', 'products_purchasable_once', 10, 2 );
function products_purchasable_once( $purchasable, $product ) {
    // Here set the product IDs in the array that can be purchased only once 
    $targeted_products = array(40021, 40038, 40171);

    // Only for logged in users and not for variable products
    if( ! is_user_logged_in() || $product->is_type('variable') )
        return $purchasable; // Exit

    $user = wp_get_current_user(); // The WP_User Object

    if ( in_array( $product->get_id(), $targeted_products ) &&
    wc_customer_bought_product( $user->user_email, $user->ID, $product->get_id() ) ) {
        $purchasable = false;
    }

    return $purchasable;
}

Code goes on function.php file of your active child theme (or active theme). Tested and works.

Here is your code with an array. Please check if it does what you want:

function sv_disable_repeat_purchase( $purchasable, $product ) {

    // Enter the ID of the product that shouldn't be purchased again
    $non_purchasable_arr = array(
        40021,
        40022
    );

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

    // Bail unless the ID is equal to our desired non-purchasable product
    foreach ( $non_purchasable_arr as $non_purchasable ) {
        if ( $non_purchasable !== $product_id ) {
            return $purchasable;
        }
    }

    // return false if the customer has bought the product
    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;
}

add_filter( 'woocommerce_variation_is_purchasable', 'sv_disable_repeat_purchase', 10, 2 );
add_filter( 'woocommerce_is_purchasable', 'sv_disable_repeat_purchase', 10, 2 );
