How to Switch Primary Sidebar to Secondary Sidebar for a Specific Page in Genesis

For one of my sites, the person wanted to use two different sidebars: one for his store and another for his blog. The rest of the site was full-width layout. So we used the two sidebars: Primary (sidebar) and Secondary (sidebar-alt). So here’s how to switch sidebars (without using Nathan’s phenomenal plugin Simple Sidebars) using functions.php.

//switch sidebars
add_action('get_header','change_genesis_sidebar');
function change_genesis_sidebar() {
    $pages = array(181);

    if ( is_page($pages)) {
        remove_action( 'genesis_sidebar', 'genesis_do_sidebar' );
        add_action( 'genesis_sidebar', 'genesis_do_sidebar_alt' );
    }
}

This code can be easily adapted to be done based on category, archives, author, etc. See the conditional tags for more details.

Add Custom CSS File Based on Page Type: Front Page, Home Page, Category Page, Archive Page, 404 Page, Author Page, and Page

So I found one question that I read that asked how to have a custom CSS file per page. Here’s an easy way to add custom CSS files based on simple conditional logic in Genesis.

remove_action('genesis_meta', 'genesis_load_stylesheet'); //removes current stylesheet
add_action('genesis_meta','genesis_custom_css');
//get_bloginfo('stylesheet_url') is our normal style.css
function genesis_custom_css() {
	if (is_category())
		echo '<link rel="stylesheet" href="'.CHILD_DIR.'/css/cat_style.css" type="text/css" media="screen" />'."n";
	if (is_home() || is_front_page())
		echo '<link rel="stylesheet" href="'.get_bloginfo('stylesheet_url').'" type="text/css" media="screen" />'."n";
	if (is_archive())
		echo '<link rel="stylesheet" href="'.CHILD_DIR.'/css/arch_style.css" type="text/css" media="screen" />'."n";
	if (is_author())
		echo '<link rel="stylesheet" href="'.CHILD_DIR.'/css/auth_style.css" type="text/css" media="screen" />'."n";
	if (is_page()) //also can take $pages=array(1,2,3); adding and elseif or else at the end.
		echo '<link rel="stylesheet" href="'.CHILD_DIR.'/css/page_style.css" type="text/css" media="screen" />'."n";
	if (is_404())
		echo '<link rel="stylesheet" href="'.CHILD_DIR.'/css/page_style.css" type="text/css" media="screen" />'."n";
}
