Change order status for virtual, downloadable, free or backorder products in WooCommerce

i try to slightly modify with +1 check for plugin located here So , for all Virtual Downloadable Free (price=0,00) & on Backorder products I want Woocommerce to set order status ‘Processing’

the result I have with code below – Woocommerce to set order status ‘Pending Payment’ Are there any ideas how to switch it to ‘Processing’:

add_action('woocommerce_checkout_order_processed', 'handmade_woocommerce_order');

function handmade_woocommerce_order( $order_id ) 
{
    $order = wc_get_order($order_id);
    foreach ($order->get_items() as $item_key => $item_values):
        $product_id = $item_values->get_product_id(); //get product id

    //get prodct settings i.e virtual
    $virtual_product = get_post_meta($product_id,'_virtual',true);
    $downloadable_product = get_post_meta($product_id,'_downloadable',true);
    $product_backordered=backorders_allowed($product_id,'_backorders',true);

    $price = get_post_meta($product_id,'_regular_price',true);

    $virtuald=get_option('hmade_vd');

    if($virtuald=='yes' && $downloadable_product=='yes' && $virtual_product=='yes' && $product_backordered=='yes')
    {
        if($price=='0.00')
        {
            $order->update_status( 'processing' );
        }

    }


endforeach;
}

Answer

Note 1: use woocommerce_thankyou hook instead

---

Note 2: To know whether a product is virtual or downloadable you can use the following functions $product->is_virtual(); and $product->is_downloadable(); opposite get_post_meta();

More info: https://docs.woocommerce.com/wc-apidocs/class-WC_Product.html

Note 3: It is better not to perform operations in a foreach loop, use a check afterwards

function handmade_woocommerce_order( $order_id ) {
    if( ! $order_id ) return;

    // Get order
    $order = wc_get_order( $order_id );

    // get order items = each product in the order
    $items = $order->get_items();

    // Set variable
    $found = false;

    foreach ( $items as $item ) {
        // Get product id
        $product = wc_get_product( $item['product_id'] );

        // Is virtual
        $is_virtual = $product->is_virtual();

        // Is_downloadable
        $is_downloadable = $product->is_downloadable();
        
        // Backorders allowed
        $backorders_allowed = $product->backorders_allowed();

        if( $is_virtual && $is_downloadable && $backorders_allowed ) {
            $found = true;
            // true, break loop
            break;
        }
    }

    // true
    if( $found ) {
        $order->update_status( 'processing' );
    }
}
add_action('woocommerce_thankyou', 'handmade_woocommerce_order', 10, 1 );
