How to duplicate page template twenty eleven child

I have. I created a page called sidebar2-page.php, which shows up in the page template drop down menu.

If a I duplicate the code from the sidebar-page file, how can I get this page template to link with other widgets on the sidebar.

I tried editing the <?php get _Sidebar();?> line. Is that correct, or no?

Ok. I can create a new page. From what I read, its:

<?php
/*
Template Name: My Custom Page
*/

Then what do I do? Naturally, the page is appearing blank, because there is nothing on the page.

It does not. I am still trying to learn some of the coding required for WordPress.

Would you be able to point me in the direction where I might be able to figure out how to tell the page to call a new custom sidebar please?

Thanks for your help alchymyth. So I added this code to the end of the functions.php file:

add_filter('body_class', 'adjust_body_class', 20, 2);
function adjust_body_class($wp_classes, $extra_classes) {

if( is_page_template('new-sidebar-page-template-file-name.php') ) :
// Filter the body classes    

      foreach($wp_classes as $key => $value) {
      if ($value == 'singular') unset($wp_classes[$key]);
      }

endif;
// Add the extra classes back untouched
return array_merge($wp_classes, (array) $extra_classes );
}

And my page is not coming up at all anymore. I hadn’t had a functions.php file yet in my child theme directory. Do I need to copy ALL files over from the 2011 theme?

That appears to be working! Thank you, although the new page is still showing the widgets from the main sidebar.

will either of the ‘conditional widgets’ or ‘widget logic’ plugins allow me to change which widgets now appear in this new page?

Thanks again for your help.

‘Conditional widgets’ is working somewhat, but I am still having difficulties getting any sidebar to appear on my newly created page.

Do I need to do anything to functions or the new page.php files?
