The ABC of Custom Post Types

You’ve juggled around with Posts and Pages, but there’s a whole new category of content eager for your attention – Custom Post Types. From reviews to recipes, portfolios to testimonials – here’s where you unlock the power to create something truly unique.
In PHP terms, they’re christened by the function register_post_type(). If you’re not into ritualistic PHP ceremonies, don’t worry; it’s just a way to tell WordPress, "Hey, I’ve got new content and it’s got its own rules!"
The command line for this would look like:

<pre><code>php function webdev101_book_custom_post_type() { register_post_type('book', array('labels' => array( 'name' => __('Books'), 'singular_name' => __('Book') ), 'public' => true, 'has_archive' => true, ) ); } add_action('init', 'webdev101_book_custom_post_type');

In this example, we just created a custom post type called ‘book.’ Go ahead, make WordPress your playground.

Introduction to Taxonomies

If custom post types are the characters in our WordPress story, then taxonomies are the plot. Or the subplot. Or even the plot twist. You probably know of categories and tags in WordPress, those are basic taxonomies. Now, imagine being able to classify your content in unique ways like by ‘color’ or ‘mood’ or ‘difficulty level’. Yes, taxonomies make your content more colorful than a rainbow!
Creating a custom taxonomy is like creating a family for your Post Types; a family that defines them and adds a whole new level of organization. For PHP enthusiasts, this is the magical spell:

<pre><code>php function webdev101_book_taxonomy() { register_taxonomy( 'genre', 'book', array( 'label' => __( 'Genre' ), 'rewrite' => array( 'slug' => 'genre' ), 'hierarchical' => true, ) ); } add_action( 'init', 'webdev101_book_taxonomy', 0 );

And we’ve just created a new taxonomy i.e. ‘genre’, for our ‘book’ custom post type!
