[Plugin: Subpages Navigation] Minor Issues With Subpages-Navigation Plugin

Installed the plugin and copied the style sheet and images as instructed in the installation information and activated the plugin.

Using Twentyten theme, I put the widget in the sidebar.

Got an error that the variable “lightbox” was not defined. To get around the problem, I inserted the following after the function definition for start_el (about line 320 in subpages-navigation.php):

if (!isset($lightbox)) {
     $lightbox = false;
}

The widget then worked as expected.

I also had a problem with the widget title being displayed even though there were no subpages. So I made another modification to subpages-navigation.php about line 112 or so to only display the title if the $pages array has something in it. The code now reads:

if(is_array($pages)):
  if (count($pages) > 0):
    echo $before_widget;
    if ( $title )
      echo $before_title . $title . $after_title;
  endif;
 ...

With this change, no widget title will be displayed unless there is content to be displayed.

With that, the plugin works the way I’d like it to work.

Thanks!
