How to create additional “Download Invoice(PDF)” buttons

Hi! Here’s a link to the documentation page that describes how to add the download PDF button on the thank you page:
https://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/download-link-on-the-thank-you-page/
To make it WPML compatible, instead of:

$text .= '<p><a href="'.esc_attr($pdf_url).'">Download a printable invoice / payment confirmation (PDF format)</a></p>';

use:

$text .= sprintf( '<p><a href="%s">%s</a></p>', esc_attr($pdf_url), __( 'Download Invoice (PDF)', 'woocommerce-pdf-invoices-packing-slips' ) );

Adding the button to the View Order page is a bit more limited, because by default WooCommerce only has one action here (your theme may have more, but you’d have to check for yourself): woocommerce_view_order
This is at the very bottom of the page…

Here’s an example that uses this action:

add_action( 'woocommerce_view_order', 'woocommerce_view_order_pdf_button', 10, 1 );
function woocommerce_view_order_pdf_button( $order_id ) {
    $pdf_url = wp_nonce_url( admin_url( 'admin-ajax.php?action=generate_wpo_wcpdf&template_type=invoice&order_ids=' . $order_id . '&my-account'), 'generate_wpo_wcpdf' );
    printf( '<p><a href="%s">%s</a></p>', esc_attr($pdf_url), __( 'Download Invoice (PDF)', 'woocommerce-pdf-invoices-packing-slips' ) );
}

Hope that helps!
