21. Theming How it all works If you go the default theme folder ( wp-content/themes/default ), you will see many PHP files (these are template files) and one style.css file. When you are viewing the front page, WordPress actually uses several template files to generate the page ( index.php << header.php , sidebar.php , and footer.php ).

24. Theming The Loop The Loop is used to display blog posts and it also lets you control what to display. Basically, The Loop checks if there are posts in your blog, while there are posts, display it, if no post found, say &quot;Not Found&quot;.

25. Theming <?php wp_list_cats('exclude=1'); ?> <?php wp_list_cats('exclude=1, 2'); ?> <?php the_content('Read the rest of this entry &raquo;'); ?> <div class=&quot;alignleft&quot;><?php next_posts_link('&laquo; Older Entries') ?></div> <div class=&quot;alignright&quot;><?php previous_posts_link('Newer Entries &raquo;') ?></div> Conditional Tags * See WordPress Codex- Conditional Tags

28. Plugins and Widgets Plugins Plugins are tools to extend the functionality of WordPress . The core of WordPress is designed to be lean, to maximize flexibility and minimize code bloat . Plugins offer custom functions and features so that each user can tailor their site to their specific needs. Widgets WordPress Widgets (WPW) is like a plugin, but designed to provide a simple way to arrange the various elements of your sidebar content (known as &quot;widgets&quot;) without having to change any code. VS. “ Plug-ins can extend WordPress to do almost anything you can imagine.” -WordPress.org * See my presentation on WordPress Plugin Development

29. Plugins and Widgets if ( function_exists('register_sidebar') ) { register_sidebar(array( 'before_widget' => '<li id=&quot;%1$s&quot; class=&quot;widget %2$s&quot;>', 'after_widget' => '</li>', 'before_title' => '<h2 class=&quot;widgettitle&quot;>', 'after_title' => '</h2>', )); } Widgetizing a theme functions.php <?php /* Widgetized sidebar, if you have the plugin installed. */ if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?> Your widgets will show up here… <?php endif; ?> sidebar.php

32. Extending BuddyPress is a suite of WordPress plugins and themes, each adding a distinct new feature. BuddyPress contains all the features you’d expect from WordPress but aims to let members socially interact. http://buddypress.org/ WordPress MU, or multi-user, is designed to do exactly that. It is most famously used for WordPress.com where it serves tens of millions of hits on millions of blogs each day. http://mu.wordpress.org/

33. Extending When a visitor browses to a WordPress.com blog on a mobile device we show special themes designed to work on small screens focussing on fast load times. The first theme is a modification of WPtouch and is displayed to phones with rich web browsers like the iPhone and Android phones. The second theme was developed from an old version of the WordPress Mobile Edition and will be displayed to all other mobile devices.
