Post Types

Languages: English • 日本語 • Português do Brasil • Nederlands • Slovenčina • (Add your language) WordPress can hold and display many different types of content. A single item of such a content is generally called a post, although post is also a specific post type. Internally, all the post types are stored in the same place, in the wp_posts database table, but are differentiated by a column called post_type. WordPress 3.0 gives you the capability to add your own custom post types and to use them in different ways. Default Post Types There are five post types that are readily available to users or internally used by the WordPress installation by default : Post (Post Type: 'post') Page (Post Type: 'page') Attachment (Post Type: 'attachment') Revision (Post Type: 'revision') Navigation menu (Post Type: 'nav_menu_item') Post Post in WordPress is a post type that is typical for and most used by blogs. Page Page in WordPress is like post, but it lives outside the normal time-based listings of posts.

Showing custom post types on your home/blog page In the last few days, I’ve shown a few people a screenshot of something I’ve been working on for this site. The screenshot is of a home page displaying custom post types and not just the post post type. After numerous requests for the code to do this, I figured it’d be much easier to share it here. WordPress version 3.0 will make creating custom post types extremely simple. Changing the post type on the home page By default, WordPress shows the post post type on your home page. page (yes, regular pages)albummoviequote To add these, open your theme’s functions.php file and paste this PHP code into it: add_filter( 'pre_get_posts', 'my_get_posts' ); function my_get_posts( $query ) { if ( is_home() && $query->is_main_query() ) $query->set( 'post_type', array( 'post', 'page', 'album', 'movie', 'quote' ) ); return $query; } That’s all there is to it. Showing the post types in your feed if ( is_home() && $query->is_main_query() ) We’ll use the is_feed() conditional tag:

Inside WordPress Actions and Filters Advertisement Gone are the days when WordPress developers, wanting to extend the CMS’ functionality, had to alter and hack WordPress’ source code directly, resulting in headaches when upgrading and sharing modifications. When WordPress 1.2 rolled out1 back in 2004, a new plugin architecture was introduced that is now commonly referred to as actions and filters, hooks, and the Plugin API. WordPress’ core has been carefully sprinkled with actions and filters that external code (in the form of themes and plugins) can hook into, injecting new functionality into the standard flow. Warning This is a detailed walkthrough of some of WordPress’ core source code. The Plugin API The functions that theme and plugin developers most commonly use are these: These functions are well-known, well-documented, and used abundantly in a majority of themes and plugins. The API is quite compact, around only 350 lines of code (the rest are comments). $wp_filter This function is defined on line 6515. Filters ref_array

Illustrated installation instructions can be found here but you can ignore the instructions to place domain_mapping.php in mu-plugins.

How to Create WordPress Shortcodes One of the primary reasons why WordPress is the most popular CMS platform available is the sheer level of customizability that it brings to the table. Today, we'll review the process of integrating one of those popular features, shortcodes, in the most user friendly way possible, into our theme. Even though there are a few trillion options to choose from, WordPress has comfortably taken the crown as the king of CMSs and blogging platforms with its incredible flexibility. A shortcode is one of those features that ratchet up the user friendliness of the system. However, most implementations still require you to remember the shortcode itself. It's called a shortcode and it has been part of the base WordPress installation since it hit version 2.5. Here, you can define your own codes to use within your theme. If you're unfamiliar with the concept of a BBCode, and by extension, shortcode, this is how the simplest version looks: There are two more variations you should also be familiar with.
