Offering complementary BOGO (Buy One Get One) offers to customers who have made previous purchases in the last ‘X’ days will lead to customer satisfaction and retention. This code helps you to automatically add a free product to a user’s cart if they have made a purchase in the last 30 days.
function ts_add_product_to_cart() {
if (!is_admin() && is_user_logged_in()) {
$free_product_id = 470; // Product ID of the free product to be added to cart
$user_id = get_current_user_id();
$found = false;
// Check if the user has made a purchase in the last 30 days
$last_30_days_orders = wc_get_orders(array(
'customer' => $user_id,
'date_query' => array(
array(
'after' => date('Y-m-d', strtotime('-30 days')),
),
),
'status' => 'completed', // Consider only completed orders
'limit' => -1,
));
if (count($last_30_days_orders) > 0) {
// Check if there are any products in the cart
if (sizeof(WC()->cart->get_cart()) > 0) {
foreach (WC()->cart->get_cart() as $cart_item_key => $values) {
// Check if the cart item is not the free product
if ($values['data']->get_id() != $free_product_id) {
$found = true;
break;
}
}
// If a non-free product is found, add the free product to the cart
if ($found) {
WC()->cart->add_to_cart($free_product_id);
}
}
}
}
}
add_action('template_redirect', 'ts_add_product_to_cart');
Output
When a custome is logged in , the code checks whether the current logged in user has completed orders in the last 30 days. and if such orders exist, the code proceeds to add the free product once the user adds any product to the cart.
