Send admin-new-order e-mail, if woocommerce order has items from a specific product category

Question

How to send "admin new order e-mail" additionally in cc to [email protected] when new order has products from category id = "99" ?

Can anyone help me?

Answer 1

I guess something like this should do the trick:

 add_filter( 'woocommerce_email_headers','stack_overflow_add_cc_to_new_order_email',10,4 );

function stack_overflow_add_cc_to_new_order_email( $header, $mail_id, $mail_obj, $wc_email ) {
    if ( $mail_id == "new_order" ) {
        $header .= "Cc: Name <[email protected]>" . "\r\n"; // del if not needed
    }
    
    return $header;
}

The explanation is simple, everytime a WC email is sent the woocommerce_email_headers is called. Inside that filter you gain access to the "id" of the email (the way wc distinguish the emails) so you can check if it's the new_order email and if so add the corrisponding header to the email.

I didn't test the code but it should work. Place that code inside your theme function.php file
