Save pdf from woocommerce email attachment

Hi!

I use e2pdf shortcode into woocommerce emails additionnal content box to generate pdf attachments.
It works well. I would like to store the pdf as well. I tried some shortcodes without result. Can you help please?
Here is my last try:
[e2pdf-save id="16" attachment="true" dir="wp-content/uploads/testdevispdf/]
The pdf is attached to the email, but not saved.

Regards

Thank you for the quick answer!
The attribute was unclosed... sorry for that.
Do you think it is possible to dynamically create the folder? I tried this:

add_action('woocommerce_order_status_changed', 'generate_pdf_on_status_change', 10, 4);

function generate_pdf_on_status_change($order_id, $old_status, $new_status, $order) {
$user_info = get_userdata($order->get_user_id());
$username = $user_info->user_login; // Récupère le nom d'utilisateur de WordPress

$uploads_dir = wp_upload_dir();
$pdf_dir = trailingslashit($uploads_dir['basedir']) . 'devispdf/' . $username . '/' . $order_id . '/';

// Assurez-vous que le répertoire existe
if (!file_exists($pdf_dir)) {
wp_mkdir_p($pdf_dir);
}

// Mettez ici le code pour générer le PDF
// Vous pouvez utiliser e2pdf avec quelque chose comme ça :
echo do_shortcode('[e2pdf-save id="1" dir="' . $pdf_dir . '" create_dir="true" create_index="true"]');
}

the path is well created and the pdf attached to the email. But it isn't saved into the created folder.

Thank you!
I don't use woocommerce > orders
Just paste the shortcode into the email additionnal content box.
Should I paste the shortcode from your code instead?

Ok sorry I thought you were talking about the e2pdf settings options. It is a "orders" template yes.

Still nothing sorry. Maybe I'm doing something wrong.
Here the working code to create the correct path: https://codefile.io/f/18yqusmwxT
But it doesn't save the pdf into the file.
and
[e2pdf-save id="16" attachment="true" dir="wp-content/uploads/testdevispdf/"]
Works great to save the pdf.

thank you again

It works. Thank you again!
