How can I hide the sidebar on specific pages?

Question

I'm using a child of the twentyten default theme and I want to hide the sidebar on some pages.

What is the solution for that?

Answer 1

Actually, Twentyten has a no-sidebar page template already.

Modify the template option in the page edit screen:

And viola:

Answer 2

create a new page template, simply duplicate the current page.php or index.php. remove the following:

<?php get_sidebar();?>

and place a template title at the top of the file

<?php
/*
Template: No-Sidebar Template
*/
?>

Then you can choose that when publishing.

NOTE: This will probably impact on your styles, may need to tweak your stylesheets.

Answer 3

You can use conditional template tags on your standard page file template

if( ! is_page('page_name')){ get_sidebar();}

or

if( ! is_page(page_id) ){ get_sidebar();}

You can also pass an array

is_page(array(42,'about-me','About Me And Joe'))
