How To Register A Sidebar In WordPress

In this tutorial we will learn how you can register a new Sidebar for your WordPress blog. The best part about WordPress sidebars is that you can use them to add Widgets to your page.


To register a sidebar you need to use the WordPress function register_sidebar().

WordPress Register Sidebar Function

<?php register_sidebar( $args ); ?>

The parameters that this accepts is a array of options.

<?php $args = array(
	'name'          => sprintf(__('Sidebar %d'), $i ),
	'id'            => 'sidebar-$i',
	'description'   => '',
	'before_widget' => '<li id="%1$s" class="widget %2$s">',
	'after_widget'  => '</li>',
	'before_title'  => '<h2 class="widgettitle">',
	'after_title'   => '</h2>' ); ?>

The options before_widget, after_widget, before_title and after_title all accept HTML tags which will be placed around the sidebar widgets.

Below is an example of creating a WordPress main sidebar add the following to your functions.php page.

if ( function_exists('register_sidebar') ) {
		'name' => 'Main Sidebar',
		'before_widget' => '<div id="%1$s" class="widget %2$s clearfix">',
		'after_widget' => '</div>',
		'before_title' => '<h3 class="widget-title">',
		'after_title' => '</h3>',

WordPress Dynamic Sidebar Function

Once you sidebar is registered you need to place this in your HTML by using the function dynamic_sidebar().

<?php dynamic_sidebar( $index ); ?>

<ul id="sidebar">
   <?php dynamic_sidebar( 'Right Sidebar' ); ?>
