WordPress is a free and open-source content management system that can be used to create blogs and websites. It has a plugin architecture and a template system that allows for great flexibility and customization. WordPress is highly extensible through plugins and has a large community that contributes plugins, themes, and translations to support users in many different languages.

- 3. Philosophy • Out of the Box - little configuration and setup; Famous 5- minute install is more like 1-minute install. • Design for the Majority - The average user wants to be able to write without problems or interruption. • Decisions not Options - Users are considered being first. Avoid putting the weight of technical choices on end users. • Clean, Lean, and Mean - It's designed to be lean and fast. The rule of thumb - core should provide features that 80% or more of end users will appreciate and use. • Striving for Simplicity - Make it easier to use with every single release. Simplicity is always an open task.

- 15. New Default Theme Twenty Twelve is ready for use. Comes with WordPress 3.5 http://wordpress.org/extend/themes/twentytwelve • Uses the latest Theme Features • And, yes, a fully responsive design • Good baseline for making Child Themes
- 16. <?php echo ‘Under the hood’; ?> • Core • Themes and Child Themes • Template Hierarchy and Custom Templates • Plugins - functions.php, self-made plugins • Functions, Classes, APIs • Hooks - Actions and Filters
- 17. Core Want to hack/modify the WordPress core? Don’t! Because: 1. You create zero-day vulnerabilities 2. You’re hacking up what plugins were made to do 3. Your site is no longer future-proof ” It is basically never really necessary. If you examine like half the core code, you’ll find that WordPress itself uses its own action and filter hooks extensively. In a sense, quite a lot of the WordPress core code is a plugin. --- Otto
- 18. Themes The minimum set of files that a WordPress theme needs is: • style.css • index.php Stylesheet header is needed, in order theme to be discovered by WordPress: /* Theme Name: Twenty Ten Theme URI: http://wordpress.org/ Description: The 2010 default theme for WordPress. Author: wordpressdotorg Author URI: http://wordpress.org/ Version: 1.0 Tags: black, blue, white, two-columns, fixed-width, custom-header, custom- background, threaded-comments, sticky-post, translation- ready, microformats, rtl-language-support, editor-style, custom-menu (optional) License: License URI: General comments (optional). */
- 19. Child Themes … inherits the functionality of another theme, called the parent theme. … are the recommended way of making modifications to a theme. Stylesheet header is needed, in order theme to be discovered by WordPress: /* Theme Name: Twenty Eleven Child Theme URI: http://example.com/ Description: Child theme for Twenty Eleven theme. Author: Your name Author URI: http://example.com/ Template: twentyeleven Version: 0.1.0 */ @import url("../twentyeleven/style.css"); #site-title a { color: #090; }
- 20. functions.php • resides in the theme directory • basically acts like a plugin • is automatically loaded during WordPress initialization (both for admin pages and external pages) • is suggested for managing theme features, defining custom functions, setting up theme options, etc. • If the logic has to be available for all themes, put it in a plugin instead… • In a child theme, functions.php is loaded prior to parent themes’ functions.php - a trouble-free method of modifying the functionality of a parent theme. • User functions of a parent theme should be pluggable - declared conditionally.
- 22. Plugins …allow easy modification, customization, and enhancement to a WordPress website. Many WordPress Plugins accomplish their goals by connecting to one or more WordPress Plugin "hooks". The way Plugin hooks work is that at various times while WordPress is running, WordPress checks to see if any Plugins have registered functions to run at that time, and if so, the functions are run. These functions modify the default behavior of WordPress. Plugin header is needed, in order plugin to be discovered by WordPress: <?php /* Plugin Name: Name Of The Plugin Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates Description: A brief description of the Plugin. Version: The Plugin's Version Number, e.g.: 1.0 Author: Name Of The Plugin Author Author URI: http://URI_Of_The_Plugin_Author License: A "Slug" license name e.g. GPL2 */ ?>
- 23. Hooks …allow your plugin to 'hook into' the rest of WordPress. 1. Actions - hooks that the WordPress core launches at specific points during execution, or when specific events occur. Your plugin can specify that one or more of its PHP functions are executed at these points, using the Action API. (near 600 in WP 3.4) 2. Filters - hooks that WordPress launches to modify text of various types before adding it to the database or sending it to the browser screen. Your plugin can specify that one or more of its PHP functions is executed to modify specific types of text at these times, using the Filter API. (more than 1000 in WP 3.4)
- 24. Sidebars and Widgets • Registered sidebars are dynamic and act like containers for a set of widgets. • Sidebars can have default content. • A theme can have many registered sidebars, placed in a different templates. • Sidebars can have own templates. • Widgets can have multiple instances • Widgets can have various options to display specific content on the front page.
