  into your themes directory or copy the content to the theme’s “style.css” file.

• Adding postbar to your blog posts
  There are two ways of inserting postbar into you blog:

  • automatic
  • manual

• Automatic installation
  If you have a simple blog (e.g. the default theme) you can easily add postbar by selecting ?Automagic insertion? in the options page. Then you can select where you want the postbar to appear:

  • Front of postings
  • Behind postings
  • Footer

+Manual installation
If the automatic insertion is not suitable for your blog because your theme has more than one posting loop you can add postbar manually to your blog by editing some of your themes files. Simply add the following code directly behind The Loop in your index.php and search.php:

 if (function_exists('postbar')) postbar();

Of course you may want to configure postbar to your needs using the option page and by editing the pagebar.css style file.

• Adding pagebar to your multipaged posts
  This pagebar can not be displayed automatically so you have to edit the file “page.php”. If your theme contains the standard navigation for multipaged posts you first have to delete the following code:

   wp_link_pages(array('before' => '
  ' . __('Pages:', 'kubrick') . ' ', 'after' => '
  ', 'next_or_number' => 'number'));

(The code does not have to look necessarily exactly the same, this example is from the WordPress default theme.) Then you can add the multipagebar to your pages:

 if (function_exists('multipagebar')) multipagebar();

You can customize the display of your multipagebar by editing the settings in the Multipagebar tab on the pagebar option page.

• Adding pagebar to your paged comments
  This pagebar can not be added automatically (there is no action indicating the end of the comment loop) so you have to edit the file “comments.php”. If your theme contains the standard navigation for paged comments you first have to delete the following code:

(The code does not have to look necessarily exactly the same, this example is from the WordPress default theme.) Then you can add the commentbar to your pages:

 if (function_exists('commentbar')) commentbar();

• Upgrading from earlier versions
  Important: the old “pagebar()” function has been renamed to “postbar()” since this seems to describe its function better. Nevertheless the old “pagebar()” function is and will be an alias.

pagebar v2.5+ introduces a new database structure for its settings. Formerly there was only one entry in “wp_options” called “pagebar”. Since there are now three different pagebars (“postbar”, “commentbar” and “multipagebar”), the options are splitted into three entries (“postbar”, “commentbar” and “multipagebar” respectively).
After installation (either through WordPress update or manually per FTP) pagebar copies the settings stored in “pagebar” to the new “postbar” entry and sets “commentbar” and “multipagebar” to inherit the settings so everything should look fine without manual interference. The “commentbar” and “multipagebar” have to be installed manually though.
