Send message after user registration via Gianism

At v3.1, Gianism does not send a message to users when they create accounts by default. It’s because some SNS don’t provide users’ email address. But sometimes some kind of users will appear who delete their SNS account without remembering email and password.

For them, we describe how to send email on user registrations.

Use wpg_connect

wpg_connect is an action hook triggered when a user registers or logs in to your WordPress via Gianism. With this hook, you can send email to a new user.

add_action( 'wpg_connect', function( $user_id, $data, $service, $on_creation ) {
    // Execute only for registration.
    if ( ! $on_creation ) {
        return;
    }
    // Get user info.
    $user = get_userdata( $user_id );
    // Send email
    $subject = 'Welcome to Gianism!';
    $message = sprintf( 'Dear %s, thank you for regisration.', $user->display_name );
    wp_mail( $user->user_email, $subject, $message );
}, 10, 4 );

Notice

Users who created their account via Gianism sometimes don’t have email addres. Describing technically, they have pseudo mail addresses like [email protected]

So you might have to check email address to avoid sending an undeliverable email.

if ( false !== strpos( $user->user_email, '@pseudo.' ) ) {
    // This user has psuedo email.
    return;
}
