Woocommerce - Need to send email to specific address based on zip code

Question

Basically, in woocommerce you have the option to input multiple email addresses (separated by commas) of who to send the completed order to, in WooCommerce -> Settings -> Em

Answer 1

Each email has a filter that allows you to adjust the recipients of that email. The filter name is essentially woocommerce_email_recipient_{$email_id}.

So the following would filter the "to" addresses for the "new_order" email.

add_filter( 'new_order' , 'so_26429482_add_recipient', 20, 2 );
function so_26429482_add_recipient( $email, $order ) {
    $additional_email = "somebody@somewhere.net";
    if( $order->shipping_postcode == "90210" ){
        $email = explode( ',', $email );
        array_push( $email, $additional_email );
    }
    return $email;
}

I'm not 100% certain on the conditional logic, but I think that should check the shipping zip code and subsequently send to the additional email address.
