Many wordpress developers and PHP developers who are new in to wordpress development. They really searching for how to add a dynamic or multiple side in wordpress theme.

Many wordpress developers got requirement to add separate sidebar for each page or any specific page and that sidebar need to be controlled by wordpress admin.

In this tutorial I will show you how to simply add the multiple or dynamic sidebar to wordpress theme. I really think creating the or putting separate css and options in  the sidebar and admin has no control over the sidebar.

Just use my code to create the multiple sidebar in wordpress theme. This following function is provided by wordpress api only. Open your functions.php file from your wordpress theme folder

<?php
 if(function_exists('register_sidebar'))
 register_sidebar(array(
 'name' => 'Home Page', // The sidebar name you can choose as per your choice to register
 'before_widget' => 'PUT YOUR OPENING CSS DIV AND CSS CLASSES AND IDS HERE',
 'after_widget' => 'CLOSE THE DIV',
 'before_title' => '<h2>',
 'after_title' => '</h2>',
 ));
?>

This is sample code for multiple pages your can use following code:

[php]
<?php
     // Home Page sidebar
     if(function_exists('register_sidebar'))
          register_sidebar(array(
          'name' => 'Home Page',
          'before_widget' => 'PUT YOUR OPENING CSS DIV AND CSS CLASSES AND IDS HERE',
          'after_widget' => 'CLOSE THE DIV',
          'before_title' => '<h3>',
          'after_title' => '</h3>',
     ));
     // Blog Page sidebar
     if(function_exists('register_sidebar'))
          register_sidebar(array(
          'name' => 'Blog Page',
          'before_widget' => 'PUT YOUR OPENING CSS DIV AND CSS CLASSES AND IDS HERE',
          'after_widget' => 'CLOSE THE DIV',
          'before_title' => '<h3>',
          'after_title' => '</h3>',
     ));
     // Contact us Page sidebar
     if(function_exists('register_sidebar'))
          register_sidebar(array(
          'name' => 'Contact Page',
          'before_widget' => 'PUT YOUR OPENING CSS DIV AND CSS CLASSES AND IDS HERE',
          'after_widget' => 'CLOSE THE DIV',
          'before_title' => '<h3>',
          'after_title' => '</h3>',
     ));
     // About us Page sidebar
     if(function_exists('register_sidebar'))
          register_sidebar(array(
          'name' => 'About us',
          'before_widget' => 'PUT YOUR OPENING CSS DIV AND CSS CLASSES AND IDS HERE',
          'after_widget' => 'CLOSE THE DIV',
          'before_title' => '<h3>',
          'after_title' => '</h3>',
     ));

?>

Here is Big question, How can you call the different sidebars and manage it. Go to wordpress admin and you will find and four side bars present in widgets sections as per this code. You can just drag and drop the widgets as your choice.

Open your sidebar.php file put following code in that file.

<?php
is_page('Home Page') {
     if (!function_exists('dynamic_sidebar') || !dynamic_sidebar('Home Page')) :
     endif;
}
?>

You can use the following type of code in your sidebar.php file as per your condition. If you have any issues get back to me.
