This extends the built-in WordPress function get_the_ID() to return the post ID both inside and outside the loop.

Used outside the loop (in header.php):

<?php if ( function_exists( 'gt_hide_nav' ) && ! gt_hide_nav() ) : ?>
  <nav role="navigation">
    <?php if ( function_exists( 'bones_main_nav' ) ) bones_main_nav(); ?>
  </nav>
