Get all WooCommerce order items for use in a variable

Question

I'm using the woocommerce_payment_complete() function to send a custom email with order details after a payment has been completed:

add_action('woocommerce_payment_complete', 'custom_process_order', 10, 1);
function custom_process_order($order_id) {
    $order      = wc_get_order( $order_id );
    $first_name = $order->get_billing_first_name();
    $last_name      = $order->get_billing_last_name();
    $company        = $order->get_billing_company();
    $email          = $order->get_billing_email();
    $order_number   = $order->get_order_number();
    $items      = $order->get_items();
    $total      = $order->get_total();
    $more_info      = $order->get_customer_note();

    foreach ($items as $item) {
        $product_name   = $item->get_name();
    }

    $to = $email;
    $subject = 'Order Details';
    $body = 'This order total is: ' . $total . '<br />First name: ' . $first_name . '<br />Last name: ' . $last_name . '<br />Company: ' . $company . '<br />Email: ' . $email . '<br />Order number: ' . $order_number . '<br />Items: ' . $product_name;
    $headers = array('Content-Type: text/html; charset=UTF-8');

    wp_mail( $to, $subject, $body, $headers );

    return $order_id;
}

It works, except for one thing. The problem is that the 'Items' ($product_name) part of the email notification only shows something if there was only one product in the order. If there is more than one product, the 'Items' show nothing.

What am I doing wrong?

The problem is in the foreach loop, with each loop you are going to overwrite the current variable (product name) with the product name of the next product.

Example:

$items = array("foo", "bar", "hello", "world");

foreach ($items as $item) {
    $product_name = $item;
}

// Result = world
echo $product_name;

The solution for this is to concatenate the string

so instead of $variable = something;

Use $variable .= something;

So you get

Example:

$items = array("foo", "bar", "hello", "world");

$product_name = '';

foreach ($items as $item) {
    // The product name
    $product_name .= $item . ' - ';
}

// Result = foo - bar - hello - world -
echo $product_name;

Solution: replace your current foreach loop with the following code

$product_name = '';

foreach ($items as $item) {
    // The product name
    $product_name .= $item->get_name() . ' - ';
}
