Add attachments based on user role to WooCommerce new user registration email - php

Question

I want to add two pdf files to the new user registration e-mail of WooCommerce.
Because I have two specific user roles customer and seller.
I want to send all new sellers two pdf files from paths $path1 and $path3 and all new customers two pdf files from paths $path2 and $path3.
I tried this in my functions.php
function attach_to_email ( $attachments, $userrole ) {
$root = ABSPATH;
$path1 = $root . '/media/AGB H.pdf';
$path2 = $root . '/media/AGB K.pdf';
$path3 = $root . '/media/W.pdf';
if ( $userrole === 'seller' ) {
$attachments[] = $path1;
$attachments[] = $path3;
} else {
$attachments[] = $path2;
$attachments[] = $path3;
}
return $attachments;
}
add_filter( 'woocommerce_email_attachments', 'attach_to_email', 10, 2 );
In the e-mail template for sellers I call:
do_action( 'woocommerce_email_attachments', null, 'seller' );
But in the function, I always enter the else part and not the if-part. In addition, all e-mails are attached with the else-files now, not only the registration e-mails. Any ideas?

To only assign the attachments to the registration e-mail, you can use:
The $email_id, where this is equal to customer_new_account
For the attachement path, linked to the theme, you can use:
get_stylesheet_directory() for a child theme
get_template_directory() for a parent theme
I would also recommend not to use spacing in the file name of the pdf file
You can then assign the correct attachments based on the user role
So you get:
function filter_woocommerce_email_attachments( $attachments, $email_id, $object, $email_object = null ) {
// Use get_stylesheet_directory() for a child theme
// Use get_template_directory() for a parent theme
$path_1 = get_template_directory() . '/my-file-1.pdf';
$path_2 = get_template_directory() . '/my-file-2.pdf';
$path_3 = get_template_directory() . '/my-file-3.pdf';
// Customer new account email
if ( isset( $email_id ) && $email_id === 'customer_new_account' ) {
// Get user role(s)
$roles = (array) $object->roles;
// Seller
if ( in_array( 'seller', $roles ) ) {
$attachments[] = $path_1;
$attachments[] = $path_3;
// Customer
} elseif ( in_array( 'customer', $roles ) ) {
$attachments[] = $path_2;
$attachments[] = $path_3;
}
}
return $attachments;
}
add_filter( 'woocommerce_email_attachments', 'filter_woocommerce_email_attachments', 10, 4 );
Code goes in functions.php file of your active theme. Tested in WooCommerce 5.0.0
