Create an order programmatically with line items in Woocommerce

Question

I needed to create a Woocommerce order programatically, however using the \'old\' Woocommerce made this a very dirty procedure.

I had to insert all kind of database

2017-2020 For WooCommerce 3 and Above

Woocommerce 3 has introduced CRUD objects and there is lot of changes on Order items… Also some WC_Order methods are now deprecated like add_coupon().

Here is a function that allow creating programmatically an order nicely with all required data in it, including the taxes:

function create_wc_order( $data ){
    $gateways = WC()->payment_gateways->get_available_payment_gateways();
    $order    = new WC_Order();

    // Set Billing and Shipping adresses
    foreach( array('billing_', 'shipping_') as $type ) {
        foreach ( $data['address'] as $key => $value ) {
            if( $type === 'shipping_' && in_array( $key, array( 'email', 'phone' ) ) )
                continue;

            $type_key = $type.$key;

            if ( is_callable( array( $order, "set_{$type_key}" ) ) ) {
                $order->{"set_{$type_key}"}( $value );
            }
        }
    }

    // Set other details
    $order->set_created_via( 'programatically' );
    $order->set_customer_id( $data['user_id'] );
    $order->set_currency( get_woocommerce_currency() );
    $order->set_prices_include_tax( 'yes' === get_option( 'woocommerce_prices_include_tax' ) );
    $order->set_customer_note( isset( $data['order_comments'] ) ? $data['order_comments'] : '' );
    $order->set_payment_method( isset( $gateways[ $data['payment_method'] ] ) ? $gateways[ $data['payment_method'] ] : $data['payment_method'] );

    $calculate_taxes_for = array(
        'country'  => $data['address']['country'],
        'state'    => $data['address']['state'],
        'postcode' => $data['address']['postcode'],
        'city'     => $data['address']['city']
    );

    // Line items
    foreach( $data['line_items'] as $line_item ) {
        $args = $line_item['args'];
        $product = wc_get_product( isset($args['variation_id']) && $args['variation_id'] > 0 ? $$args['variation_id'] : $args['product_id'] );
        $item_id = $order->add_product( $product, $line_item['quantity'], $line_item['args'] );

        $item    = $order->get_item( $item_id, false );

        $item->calculate_taxes($calculate_taxes_for);
        $item->save();
    }

    // Coupon items
    if( isset($data['coupon_items'])){
        foreach( $data['coupon_items'] as $coupon_item ) {
            $order->apply_coupon(sanitize_title($coupon_item['code']));
        }
    }

    // Fee items
    if( isset($data['fee_items'])){
        foreach( $data['fee_items'] as $fee_item ) {
            $item = new WC_Order_Item_Fee();

            $item->set_name( $fee_item['name'] );
            $item->set_total( $fee_item['total'] );
            $tax_class = isset($fee_item['tax_class']) && $fee_item['tax_class'] != 0 ? $fee_item['tax_class'] : 0;
            $item->set_tax_class( $tax_class ); // O if not taxable

            $item->calculate_taxes($calculate_taxes_for);

            $item->save();
            $order->add_item( $item );
        }
    }

    // Set calculated totals
    $order->calculate_totals();
        
    if( isset($data['order_status']) ) {
        // Update order status from pending to your defined status and save data
        $order->update_status($data['order_status']['status'], $data['order_status']['note']);
        $order_id = $order->get_id();
    } else {
        // Save order to database (returns the order ID)
        $order_id = $order->save();
    }
    
    // Returns the order ID
    return $order_id;
}

Code goes in function.php file of your active child theme (or active theme) or in a plugin file.

USAGE EXAMPLE from a data array:

create_wc_order( array(
    'address' => array(
        'first_name' => 'Fresher',
        'last_name'  => 'StAcK OvErFloW',
        'company'    => 'stackoverflow',
        'email'      => 'test1@testoo.com',
        'phone'      => '777-777-777-777',
        'address_1'  => '31 Main Street',
        'address_2'  => '',
        'city'       => 'Chennai',
        'state'      => 'TN',
        'postcode'   => '12345',
        'country'    => 'IN',
    ),
    'user_id'        => '',
    'order_comments' => '',
    'payment_method' => 'bacs',
    'order_status'   => array(
        'status' => 'on-hold',
        'note'   => '',
    ),
    'line_items' => array(
        array(
            'quantity' => 1,
            'args'     => array(
                'product_id'    => 37,
                'variation_id'  => '',
                'variation'     => array(),
            )
        ),
    ),
    'coupon_items' => array(
        array(
            'code'         => 'summer',
        ),
    ),
    'fee_items' => array(
        array(
            'name'      => 'Delivery',
            'total'     => 5,
            'tax_class' => 0, // Not taxable
