Wordpress Registration Email by Role

Question

I'm wanting to send out a custom html email to a new user based on their role during registration. So, I have 2 roles that will be specifically registering on the site: photographer and subscriber and I want one email welcoming photographers to the site and another email sent when subscribers register.

I know this is a pluggable function and you have to override it in a plugin - started with this post but it doesn't address different emails by roles. Not sure if I can create an if statement that says if current user is role because I'm not sure if current user is coming into factor when the suer is being created, if that makes sense. Any direction on this would be greatly appreciated, thank you!

Scroll down a little bit, most of it is WordPress default code but you must add everything to your plugin or you might break it! I've also added few useful snippets below. Copy-paste them to same plugin.

<?php

/*
 * Plugin Name: Emails
 * Plugin URI: http://www.your-site.com
 * Description: Different registration email for different roles
 * Author: Your name
 * Author URI: http://www.your-site.com
*/ 

// Registration email
if( ! function_exists( 'wp_new_user_notification' ) ) {

    function wp_new_user_notification( $user_id, $deprecated = null, $notify = '' ) {

        if ( $deprecated !== null ) {

            _deprecated_argument( __FUNCTION__, '4.3.1' );
        }

        global $wpdb, $wp_hasher;
        $user = get_userdata( $user_id );

        // The blogname option is escaped with esc_html on the way into the database in sanitize_option
        // we want to reverse this for the plain text arena of emails.
        $blogname = wp_specialchars_decode(get_option('blogname'), ENT_QUOTES);

        // Message that gets sent to admin if new user registers
        $message  = sprintf(__('New user registration on your site %s:'), $blogname) . "\r\n\r\n";
        $message .= sprintf(__('Username: %s'), $user->user_login) . "\r\n\r\n";
        $message .= sprintf(__('Email: %s'), $user->user_email) . "\r\n";

        @wp_mail(get_option('admin_email'), sprintf(__('[%s] New User Registration'), $blogname), $message);

        // `$deprecated was pre-4.3 `$plaintext_pass`. An empty `$plaintext_pass` didn't sent a user notifcation.
        if ( 'admin' === $notify || ( empty( $deprecated ) && empty( $notify ) ) ) {
            return;
        }

        // Generate something random for a password reset key.
        $key = wp_generate_password( 20, false );

        /** This action is documented in wp-login.php */
        do_action( 'retrieve_password_key', $user->user_login, $key );

        // Now insert the key, hashed, into the DB.
        if ( empty( $wp_hasher ) ) {
            require_once ABSPATH . WPINC . '/class-phpass.php';
            $wp_hasher = new PasswordHash( 8, true );
        }
        $hashed = time() . ':' . $wp_hasher->HashPassword( $key );
        $wpdb->update( $wpdb->users, array( 'user_activation_key' => $hashed ), array( 'user_login' => $user->user_login ) );



        ///////////////////////////////////////////////////////////////////
        //  Your code starts here, rest of it is WordPress default code  //
        ///////////////////////////////////////////////////////////////////

        // First role
        if( $user->roles == 'some_vip_role' ) {

            $email_subject = 'Welcome VIP!';

            $message = 'message content for VIP';
        } 
        // Second role
        else if( $user->roles == 'some_other_role' ) {

            $email_subject = 'Welcome other role!';

            $message = 'message content for other role';
        }

        // And so on.. 


        // Send email
        wp_mail( $user->user_email, $email_subject, $message );


        ////////////////////////////////////////////////////////////
        //  Make sure to add this link to each $message           //
        //  This is where user can set his/her first password     //
        ////////////////////////////////////////////////////////////
        $message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . ">\r\n\r\n";

    }   
}

• Play around with roles and make sure that everything works properly.
• Also add else statement to the end and use a generic $email_subject and $message in case you'll add a new role in future and forget to change the plugin.
• List of properties that $user object has can be found here.
• Don't forget to add a link where user has to go to set a password!
• Again: test, test and test - make several dummy users with different roles to test it out.

Few other useful snippets - add them before main function, just in case:

// Change "from" email
add_filter( 'wp_mail_from', 'new_mail_from_name' );

function new_mail_from_name() {

    return '[email protected]';
}


// Change "from" name
add_filter( 'wp_mail_from_name', 'new_mail_from' );

function new_mail_from() {

    return 'Your site';
}

Happy coding and let me know how it worked out for you.
