Creating a different side bar for single posts than for main page.

Question

How can I create a different side bar for single posts than for main page?

At the moment I have 2 working one for pages and one for the blog

thanks

this is how it looks in funtions.php

// Register Sidebars
register_sidebar(array('name' => 'Sidebar Blog','id' => 'sidebar-blog'));
register_sidebar(array('name' => 'Sidebar Pages','id' => 'sidebar-pages'));
register_sidebar(array('name' => 'Footer','id' => 'sidebar-footer'));

// Register Menus
register_nav_menu( 'top_navi', 'Top Navigation' );
register_nav_menu( 'main_navi', 'Main Navigation' );

this is how it looks in sidebar.php

<div id="sidebar">  
    <ul>

<?php
    if(is_page() && is_active_sidebar('sidebar-pages')) : dynamic_sidebar('sidebar-pages');
    elseif(is_active_sidebar('sidebar-blog')) : dynamic_sidebar('sidebar-blog');
else : ?>

    <?php wp_list_categories('title_li=<h2>Categories</h2>'); ?>

    <?php wp_list_pages('title_li=<h2>Pages</h2>'); ?>

    <li><h2>Archives</h2>
        <ul>
        <?php wp_get_archives(); ?>
        </ul>
    </li>

    <?php wp_list_bookmarks(); ?>

<?php endif; ?>

    </ul>
</div>

Thanks !

Answer 1

I would consider the following ...

Register a new sidebar:

function your_new_widget() {
register_sidebar( array(
    'name'          => __( 'Single View Sidebar', 'your_textdomain' ),
    'id'            => 'sidebar-single',
    'description'   => __( 'This widget area is found only on the single post view.', 'your_textdomain' ),
) );
}
add_action( 'widgets_init', 'your_new_widget' );

Create a new sidebar template:

/** New file: sidebar-single.php */
if ( is_active_sidebar( 'sidebar-single' ) ) :
    dynamic_sidebar( 'sidebar-single' );
endif;

Then modify your 'single.php' template to call the new sidebar (above):

/** Modify single.php */
get_sidebar( 'single' );

Of course you will need to flesh out the new single view sidebar template file ... and the WordPress Template Hierarchy will take care of using your new sidebar on single post views.

Answer 2

Register the sidebars:

register_sidebar(array('name' => 'Sidebar Blog','id' => 'sidebar-blog'));
register_sidebar(array('name' => 'Sidebar Pages','id' => 'sidebar-pages'));
register_sidebar(array('name' => 'Sidebar Post','id' => 'sidebar-posts'));

Then, in your sidebar template, use the is_page() and is_single() conditional tags:

if( is_page() && is_active_sidebar('sidebar-pages') ){
     dynamic_sidebar('sidebar-pages');

}elseif( is_single() && is_active_sidebar('sidebar-posts') ){
     dynamic_sidebar('sidebar-posts');

}elseif( is_active_sidebar('sidebar-blog') ){
     dynamic_sidebar('sidebar-blog');

}else{
    //Default
}
