    'friend'  => 'A friend or colleague',

    if ( isset( $wpide_referral_options[ $value ] ) ) {
        update_user_meta( $user_id, 'wpide_referral', $value );
    }
} );

add_filter( 'manage_users_columns', function ( $columns ) {
    $columns['wpide_referral'] = 'Found us via';

    return $columns;
} );

add_filter( 'manage_users_custom_column', function ( $output, $column, $user_id ) use ( $wpide_referral_options ) {
    if ( 'wpide_referral' === $column ) {
        $value  = get_user_meta( $user_id, 'wpide_referral', true );
        $output = isset( $wpide_referral_options[ $value ] ) ? esc_html( $wpide_referral_options[ $value ] ) : '&mdash;';
    }

    return $output;
}, 10, 3 );
