Save custom cart item data from dynamic created cart on order creation in Woocommerce

Question

Important note: I am not using functions.php for any cart functionality. I am using standalone php files, it has to stay this way.

In Woocommerce, I'm creating a cart dynamically adding a product using:

global $woocommerce;
$cart = $woocommerce->cart;

//set the custom item data
$item_data = array();

 $product_id = '121';

 $item_data = array(
 'plain_data' => 'test data',
 'array_data' => array('URL' => 'URL',  'Signals' => 'SIGNALS')
  );

//Add it to the cart
$cart->add_to_cart($product_id, 1, null, null, $item_data);

Then I create the order from the cart using:

global $woocommerce;
$cart = $woocommerce->cart;

$order_data = array('payment_method' => 'PayPal');

$checkout = $woocommerce->checkout();
$order_id = $checkout->create_order($order_data);

But the custom item data that I added does not get saved in the order.

What am I doing wrong?

As you don't want to use any hook, you will be oblige to set the custom cart item data afterwards once the order is created… So try the following:

Try the following:

$product_id = '121';

$item_data = array(
    'plain_data' => 'test data',
    'array_data' => array('URL' => 'URL',  'Signals' => 'SIGNALS')
);

$item_data_keys = array_keys($item_data); // Get array keys


//Add it to the cart
WC()->cart->add_to_cart($product_id, 1, 0, array(), $item_data);

// Create order
$order_id = WC()->checkout->create_order( array('payment_method' => 'PayPal') );

// Get an instance of the WC_Order Object
$order = wc_get_order($order_id);

// Loop through order items
foreach( $order->get_items() as $item ){
    // Loop though custom item data
    foreach( $item_data_keys as $item_data_key ){
        // set custom item data
        $item->update_meta_data( $item_data_key, $item_data[$item_data_key] );
    }
    // Save item data
    $item->save();
}
// Save order
$order->save();

Tested and works.

NOTE: global woocommerce is now replaced by WC() since a while.
