Showing user_id on invoice / packing list

Hi @petebm,

It might be challenging if you have no coding experience, but the easiest way is with a filter. Please read our documentation: Displaying customer numbers

If you have never worked with code snippets or functions.php please read this too: Using filters

If this is all over your head I would recommend upgrading to the Pro version. It’s way easier to implement user ids there. And you also get our premium support so we can help you out.

I hope this helps.

Have a great day!

With kind regards,

Michael

Hi Michael

Thank you very much for your reply. With some trepidation I followed your links (the second link to Code Snippets on your ‘How to use filters’ page seems to be broken, btw), copied the code into a new snippet, activated it – and lo & behold, much to my surprise, the customer number appeared on your invoice.
The only problem is . . . I misled you when I said it was the it was the user_id that I needed; it is in fact user_login, which is what we’re using as the unique identifier for our members. I tried just editing the snippet to read that, but of course that was expecting too much, & the invoice failed.
Could I trouble you to suggest how I could get that?

Thanks again
Pete

Hi Pete,
You would have to load the WordPress user data, here’s an example:

add_action( 'wpo_wcpdf_after_order_data', 'wpo_wcpdf_customer_username', 10, 2 );
function wpo_wcpdf_customer_username ($template_type, $order) {
    if ($user_id = $order->get_user_id()) {
        $user_info = get_userdata($user_id);
        ?>
        <tr class="customer-number">
            <th>Username:</th>
            <td><?php echo $user_info->user_login; ?></td>
        </tr>
        <?php
    }
}

Hope that helps!
