yes, you can, if you have a plugin installed that generates invoice numbers for you. woocommerce and woocommerce delivery notes has no concept of invoice numbering, so you need another plugin that can do that (but not this one).

otherwise, in the faq you can learn how to add custom fields to the print template:

How can I add some more fields to the order info section?

Use the wcdn_order_info_fields filter hook. It returns all the fields as array. Read the WooCommerce documentation to learn how you get custom checkout and order fields. Tip: To get custom meta field values you will most probably need the get_post_meta( $order->id, ‘your_meta_field_name’, true); function and of course the your_meta_field_name.

An example that adds a ‘VAT’ and ‘Customer Number’ field to the end of the list. Paste the code in the functions.php file of your theme:

function my_custom_order_fields( $fields, $order ) {
    $new_fields = array();

    if( get_post_meta( $order->id, 'your_meta_field_name', true ) ) {
        $new_fields['your_meta_field_name'] = array(
            'label' => 'VAT',
            'value' => get_post_meta( $order->id, 'your_meta_field_name', true )
        );
    }

    if( get_post_meta( $order->id, 'your_meta_field_name', true ) ) {
        $new_fields['your_meta_field_name'] = array(
            'label' => 'Customer Number',
            'value' => get_post_meta( $order->id, 'your_meta_field_name', true )
        );
    }

    return array_merge( $fields, $new_fields );
}
add_filter( 'wcdn_order_info_fields', 'my_custom_order_fields', 10, 2 );

i’m glad that you all try to fix the issue. i’m working on it, but it needs more time. would you people help me testing when it is ready?

@robertfarkle thanks a lot for your help. i’m aware of the problem. there is another thread with users that have the same issue.

i try to work on the problem theses next days but i can’t test it, because i do not have ssl.

do you have a github account and could help with the testing?

Do you use ssl (https)?

@blb078 save your permalink settings after you disabled ssl and try again. What happens?

ok, the next version (3.0.5) will use the invoice. for people who want something else, there will be a filter hook for it. use ‘invoice’, ‘delivery-note’ or ‘order’ as return value:

function my_theme_print_button_type( $type ) {
	return 'order';
}
add_filter( 'wcdn_theme_print_button_template_type', 'my_theme_print_button_type' );

ah i see. try it like that:

function my_custom_product_fields($fields, $product, $order) {
		$fields[] = array(
			'label' => 'SKU:',
			'value' => $product->get_sku()
		);
	return $fields;
}
add_filter( 'wcdn_order_item_fields', 'my_custom_product_fields', 10, 3);
