Add sidebar to front page twentytwelve template?

like a right sidebar?

just go to edit page
>page attributes
>template

and then choose right sidebar on the dropdown menu

Do not edit the Twenty Twelve theme. It is the default WordPress theme and having access to an unedited version of the theme is vital when dealing with a range of site issues. First create a child theme for your changes.

Did you find a solution to this jgold723?
I’m looking to do the same thing

Ok so OP was looking for a front page template which adds the Main Sidebar and both front page widget areas to the page

My last post was explaining how to create a new widget area for the front page which is a little off topic. I’ll leave the post for anyone looking to create a new widget area.

To answer the post, inside your child theme create a frontpage.php to override the twentytwelve frontpage.php template (or create a new template if your heart desires).

Paste the following code into the new template you created in the child theme. Go to the page you have set as your front page ( Pages -> Home ) and select the template from the template dropdown. The code below will create a “Front Page Template” so select that from the dropdown and things should work. I think OP may have been forgetting to select the template in the dropdown bc his code/logic appears correct.

<?php
/**
 * Template Name: Front Page Template
 *
 * Description: A page template that provides a key component of WordPress as a CMS
 * by meeting the need for a carefully crafted introductory page. The front page template
 * in Twenty Twelve consists of a page content area for adding text, images, video --
 * anything you'd like -- followed by front-page-only widgets in one or two columns.
 *
 * @package WordPress
 * @subpackage Twenty_Twelve
 * @since Twenty Twelve 1.0
 */

get_header(); ?>

	<div id="primary" class="site-content">
		<div id="content" role="main">

			<?php while ( have_posts() ) : the_post(); ?>
				<?php if ( has_post_thumbnail() ) : ?>
					<div class="entry-page-image">
						<?php the_post_thumbnail(); ?>
					</div><!-- .entry-page-image -->
				<?php endif; ?>

				<?php get_template_part( 'content', 'page' ); ?>

			<?php endwhile; // end of the loop. ?>

		</div><!-- #content -->
	</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_sidebar( 'front' ); ?>
<?php get_footer(); ?>

joshi, this set of instructions should help you out:

Add another widget area to Twenty Twelve front page template in a child theme
http://pinkishhue.com/add-another-widget-area-to-twenty-twelve-front-page-template-in-a-child-theme

I add a new sidebar with 3 columns, but i don´t know, what i have to write in the “style.css” in my child theme. Under this new sidebar, i use also the old sidebar with 2 columns.

functions.php

<?php
/**
 * Register additional widget areas for front page.
 */
function mytheme_widgets_init() {
	register_sidebar( array(
		'name' => __( 'Third Front Page Widget Area', 'twentytwelve' ),
		'id' => 'sidebar-4',
		'description' => __( 'Appears when using the optional Front Page template with a page set as Static Front Page', 'twentytwelve' ),
		'before_widget' => '<aside id="%1$s" class="widget %2$s">',
		'after_widget' => '</aside>',
		'before_title' => '<h3 class="widget-title">',
		'after_title' => '</h3>',
	) );

	register_sidebar( array(
		'name' => __( 'Fourth Front Page Widget Area', 'twentytwelve' ),
		'id' => 'sidebar-5',
		'description' => __( 'Appears when using the optional Front Page template with a page set as Static Front Page', 'twentytwelve' ),
		'before_widget' => '<aside id="%1$s" class="widget %2$s">',
		'after_widget' => '</aside>',
		'before_title' => '<h3 class="widget-title">',
		'after_title' => '</h3>',
	) );

	register_sidebar( array(
		'name' => __( 'Fifth Front Page Widget Area', 'twentytwelve' ),
		'id' => 'sidebar-6',
		'description' => __( 'Appears when using the optional Front Page template with a page set as Static Front Page', 'twentytwelve' ),
		'before_widget' => '<aside id="%1$s" class="widget %2$s">',
		'after_widget' => '</aside>',
		'before_title' => '<h3 class="widget-title">',
		'after_title' => '</h3>',
	) );
}
add_action( 'widgets_init', 'mytheme_widgets_init' );
?>

sidebar-front2.php

<?php

if ( ! is_active_sidebar( 'sidebar-4' ) && ! is_active_sidebar( 'sidebar-5' ) && ! is_active_sidebar( 'sidebar-6' ))
	return;

// If we get this far, we have widgets. Let do this.

<?php get_sidebar( 'front' ); ?>

Please post that on your own thread.

So, I found the right css I think but any changes affected all the widget boxes and it got really messy.
