    I need help with a code implementation. I am using the below code to display a specific widget on page parent (level 1) and child pages (level 2) however I realized I also need to have the widget on a third level (grand children) pages.

    To make it more clear, the code is working fine for the first two levels:
    > Parent (special widget shows)
    >> Child (special widget shows)
    >>> Grand Child ( special widget is not showing)

    This is the code:

    <?php if (is_page( '8' ) || '8' == $post->post_parent) { ?>
   Special widget
  <?php } else { ?>
  <?php } ?>

    Does anyone know how to implement this code to check if the page “8” is an ancestor?

    Thanks in advance.

  • Here is the Codex for checking post ancestors.

    <?php if( count(get_post_ancestors($post->ID)) == 2 )
    echo 'this is grandchild of top page';
?>
    <?php if( count(get_post_ancestors($post->ID)) >= 2 )
    echo 'this is grandchild of some page';
?>

    Thanks Josh. I was able to use a different method.

    Added to functions.php

    function is_tree( $pid ) {
    global $post;              

    if ( is_page($pid) )
        return true;    

    $anc = get_post_ancestors( $post->ID );
    foreach ( $anc as $ancestor ) {
        if( is_page() && $ancestor == $pid ) {
            return true;
        }
    }
    return false;
}

    and the sidebar.php

    <?php if (is_page( '8' ) || '8' == $post->post_parent || is_tree('8')) { ?>
   Special widget
  <?php } else { ?>
  <?php } ?>

    Awesome ??

    Thanks for posting your results!
