Custom Sidebars


			


				Posted on February 10, 2012 by babbler			


				
				

				
Register Custom Sidebars in THEME/functions.php


 HTML |  copy code |? 
01
add_action( 'widgets_init', 'my_register_sidebars' );
02
 
03
function my_register_sidebars() {
04
 
05
    register_sidebar( array(
06
 'name' => __( 'Primary Widget Area'),
07
 'id' => 'primary-widget-area',
08
 'description' => __( 'The primary widget area' ),
09
 'before_widget' => '<li id="%1$s" class="widget-container %2$s">',
10
 'after_widget' => '</li>',
11
 'before_title' => '<h3 class="widget-title">',
12
 'after_title' => '</h3>',
13
 ) );
14
 
15
    register_sidebar(array(
16
        'id' => 'topwidget',
17
        'name' => __('Top Widget'),
18
        'description' => __('Widget area between nav bar and content on index page'),
19
'before_widget' => '<li id="%1$s">',
20
'after_widget' => '</li>',
21
        'before_title' => '<h3 class="widget-title">',
22
        'after_title' => '</h3>' . "\n\t"
23
    ));
24
    register_sidebar(array(
25
        'id' => 'shop',
26
        'name' => __('Shop Sidebar'),
27
        'description' => __('Sidebar for shop custom post type'),
28
&nbsp; &nbsp; &nbsp; &nbsp;&nbsp; 'before_widget' => '<li id="%1$s">',
29
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'after_widget' => '</li>',
30
        'before_title' => '<h3 class="widget-title">',
31
        'after_title' => '</h3>' . "\n\t"
32
    ));
33
}


Create sidebar-mycustom.php.

You will see your sidebars now listed in ‘Appearance’ -> ‘Widgets’.


In your sidebar-templates you may now call the dynamic generated content (widgets) by the name of your sidebars eg in sidebar-mycustom.php:


 PHP |  copy code |? 
1
<?php if ( function_exists ( dynamic_sidebar('custom') ) ) : ?>
2
... regular html ...
3
<?php dynamic_sidebar ('custom'); ?>
4
... regular html ...
5
<?php endif; ?>


Integrate your sidebars in your template-files (e.g. index.php, single.php, archives.php):


Default sidebar:


 PHP |  copy code |? 
1
<?php get_sidebar (); ?>


Custom Sidebar:


 PHP |  copy code |? 
1
<?php get_sidebar ('mycustom'); ?>


Notes:


    

  • sidebar file name does not need to be relates to the registered sidebar name
    • 

  • registered name is used to call the dynamic sidebar eg: custom
    • 

  • custom sidebar file is called from template using get_sidebar(‘mycustom’)
    •

				Posted on January 27, 2012 by babbler			


				
				

				
Template files can be saved in /wp-content/themes/YOUR-THEME/nggallery and called in the short tag parameters.

1
[album id=3 template=coolone]
