[SOLVED] Add update or remove WooCommerce shipping order items

Add update or remove WooCommerce shipping order items

I have added shipping cost for the orders that are synced from Amazon. For some reason I had to set custom shipping flat price in woo-orders created for Amazon-order. It is done as follow:

    $OrderOBJ = wc_get_order(2343);
    $item = new WC_Order_Item_Shipping();

    $new_ship_price = 10;

    $shippingItem = $OrderOBJ->get_items('shipping');

    $item->set_method_title( "Amazon shipping rate" );
    $item->set_method_id( "amazon_flat_rate:17" );
    $item->set_total( $new_ship_price );
    $OrderOBJ->update_item( $item );

    $OrderOBJ->calculate_totals();
    $OrderOBJ->save()

The problem is, I have to update orders in each time the status is changed in Amazon, there is no problem doing that, problem is I have to update the shipping cost also if it is updated. But I have not found anyway to do so. Can anyone tell me how to update the shipping items of orders set in this way? Or is it the fact that, once shipping item is set then we cannot update or delete it?

Solution

To add or update shipping items use the following:

$order_id = 2343;
$order    = wc_get_order($order_id);
$cost     = 10;
$items    = (array) $order->get_items('shipping');
$country  = $order->get_shipping_country();

// Set the array for tax calculations
$calculate_tax_for = array(
    'country' => $country_code,
    'state' => '', // Can be set (optional)
    'postcode' => '', // Can be set (optional)
    'city' => '', // Can be set (optional)
);

if ( sizeof( $items ) == 0 ) {
    $item  = new WC_Order_Item_Shipping();
    $items = array($item);
    $new_item = true;
}
   
// Loop through shipping items
foreach ( $items as $item ) {
    $item->set_method_title( __("Amazon shipping rate") );
    $item->set_method_id( "amazon_flat_rate:17" ); // set an existing Shipping method rate ID
    $item->set_total( $cost ); // (optional)

    $item->calculate_taxes( $calculate_tax_for ); // Calculate taxes

    if( isset($new_item) && $new_item ) {
        $order->add_item( $item );
    } else {
        $item->save();
    }
}
$order->calculate_totals(); // Recalculate totals and save

It should better work…

To remove shipping items use the following:

$order_id = 2343;
$order    = wc_get_order($order_id);
$items    = (array) $order->get_items('shipping');

if ( sizeof( $items ) > 0 ) {
    // Loop through shipping items
    foreach ( $items as $item_id => $item ) {
        $order->remove_item( $item_id );
    }
    $order->calculate_totals(); // Recalculate totals and save
}
