    }
} );

add_action( 'wp_footer', function () {
    $text = get_site_option( 'wpide_network_footer', '' );

    if ( '' !== trim( $text ) ) {
        echo '<div class="wpide-network-footer" style="text-align:center;font-size:13px;padding:12px 16px;opacity:.8">' . wp_kses_post( $text ) . '</div>';
    }
} );
```

## Notes

Leave the field empty to hide it. Styled lightly so it fits most themes; adjust the inline CSS to match yours.
