How to set a maximum limit in WooCommerce orders per item & per day

I want to allow only a specific number of orders per product per day on my shop. Any idea which hook do I have to add?

Thanks

Answer

The code below uses the product ID to get the total quantity for the current day. If this is higher than or equal to the $dailyOrderLimit that you set (in my example, it’s 10), the product cannot be purchased.

add_filter('woocommerce_is_purchasable', 'preventPurchaseIfDailyOrderLimitReached', 10, 2);

function preventPurchaseIfDailyOrderLimitReached($is_purchasable, $product)
{
    $dailyOrderLimit = 10;
    $productId = $product->get_id();
    $quantityOrderedToday = getDailyOrderAmount($productId);

    if ($quantityOrderedToday >= $dailyOrderLimit) {
        $is_purchasable = false;
    }

    return $is_purchasable;
}

function getDailyOrderAmount($productId)
{
    global $wpdb;
    $today = date('Y-m-d');
    $result = $wpdb->get_results("SELECT sum(product_qty) as quantity_ordered_today FROM {$wpdb->prefix}wc_order_product_lookup where product_id= {$productId} and date_created > '{$today} 00:00:00';");

    return $result[0]->quantity_ordered_today;
}

Code is tested and works. Add it to the functions.php file of your child theme.
