Registering and Displaying WordPress Custom Post Types In a Very Easy Way

In WordPress, you can define custom post types. It means that you can have on you wp-admin menu, more menu items, besides “Posts”, “Midia”, “Links”, “Pages”, etc, and work with your new post type as you do with the default menus, categorizing, adding content, etc.
No WordPress, você pode definir tipos de posts personalizados. Isso significa que você pode ter no seu menu do wp-admin, mais itens de menu além de “Posts”, “Mídia”, “Links”, “Páginas”, etc, e trabalhar com els como faz com os tipos padrão, categorizando, adicionando conteúdo, etc.

Let’s create a new custom post type. Open your functions.php file, on your theme directory, and paste the code bellow.
Vamos criar um novo tipo de post personalizado Abra seu arquivo functions.php, no diretório de seu tema, e cole o código abaixo.

// The register_post_type() function is not to be used before the 'init'.
add_action( 'init', 'videos_init' );

/* Here's how to create your customized labels */
function videos_init() {
	$labels = array(
		'name' => _x( 'Videos', 'custom post type generic name' ), // Tip: _x('') is used for localization
		'singular_name' => _x( 'Videos', 'individual custom post type name' ),
		'add_new' => _x( 'Add New', 'add' ),
		'add_new_item' => __( 'Add New Video' ),
		'edit_item' => __( 'Edit Video' ),
		'new_item' => __( 'New Video' ),
		'view_item' => __( 'View Video' ),
		'search_items' => __( 'Search Videos' ),
		'not_found' =>  __( 'No Video Found' ),
		'not_found_in_trash' => __( 'No Video Found in trash' ),
		'parent_item_colon' => ''
	);

	// Create an array for the $args
	$args = array( 'labels' => $labels, /* NOTICE: the $labels variable is used here... */
		'public' => true,
		'publicly_queryable' => true,
		'show_ui' => true,
		'query_var' => true,
		'rewrite' => true,
		'capability_type' => 'post',
		'hierarchical' => false,
		'menu_position' => null,
		'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
	); 

	register_post_type( 'video', $args ); /* Register it and move on */
}

Now you got a new menu on your wp-admin, called Videos. For further info about the register_post_type() function, visit the Codex.
Agora você tem um novo menu no seu wp-admin, chamado Videos. Para mais informações sobre a função register_post_type(), visite o Codex.

What about creating a category and a tag for this new Videos menu? Paste the code bellow on your functions.php
Que tal criar uma categoria e uma tag para este novo menu Videos? Cole o código abaixo em seu arquivo functions.php

// hook into the init action and call create_book_taxonomies() when it fires
add_action( 'init', 'create_video_taxonomies', 0 );

// create two taxonomies, genres and writers for the post type "videos"
function create_video_taxonomies() {

	// Add new taxonomy, make it hierarchical (like categories)
	$labels = array(
		'name' => _x( 'Genres', 'taxonomy general name' ),
		'singular_name' => _x( 'Genres', 'taxonomy singular name' ),
		'search_items' =>  __( 'Search Genres' ),
		'all_items' => __( 'All Genres' ),
		'parent_item' => __( 'Main Genre' ),
		'parent_item_colon' => __( 'Main Genre:' ),
		'edit_item' => __( 'Edit Genre' ),
		'update_item' => __( 'Update Genre' ),
		'add_new_item' => __( 'Add Genre' ),
		'new_item_name' => __( 'New Genre Name' ),
	); 	

	register_taxonomy( 'genre', array( 'video' ), array(
		'hierarchical' => true,
		'labels' => $labels, /* NOTICE: Here is where the $labels variable is used */
		'show_ui' => true,
		'query_var' => true,
		'rewrite' => array( 'slug' => 'genre' ),
	));
	// Add new taxonomy, NOT hierarchical (like tags)
	$labels = array(
		'name' => _x( 'Actor', 'Actor Name' ),
		'singular_name' => _x( 'Actor', 'Individual Actor Name' ),
		'search_items' =>  __( 'Search Actors' ),
		'popular_items' => __( 'Popular Actors' ),
		'all_items' => __( 'All Actors' ),
		'parent_item' => null,
		'parent_item_colon' => null,
		'edit_item' => __( 'Edit Actors' ),
		'update_item' => __( 'Update Actor' ),
		'add_new_item' => __( 'Add New Actor' ),
		'new_item_name' => __( 'New Actor Name' ),
		'separate_items_with_commas' => __( 'Separate Actors With Commas' ),
		'add_or_remove_items' => __( 'Add or Remove Actors' ),
		'choose_from_most_used' => __( 'Choose From Most Used Actors' )
	);
	register_taxonomy( 'actor', 'video', array(
		'hierarchical' => false,
		'labels' => $labels, /* NOTICE: the $labels variable here */
		'show_ui' => true,
		'query_var' => true,
		'rewrite' => array( 'slug' => 'actor' ),
	));
} // End of create_video_taxonomies() function.

We’ve created two taxonomies for the custom post type video. Genre(hierarchical), works as a category. Actor(not hierarchical), works as a tag. For further info about the register_taxonomy() function, visit the Codex.

So much hard working! Now let’s have fun 🙂 , let’s display the posts.
Quanta trabalheira! Agora vamos nos divertir 🙂 , vamos exibir os posts.

<?
// * if you want to work with the genre category on your query
// $wp_query = new WP_Query(array('post_type' => 'video', 'genre' => 'scifi','posts_per_page' => -1));
//
// * if you want to work with the actor tag on your query
// $wp_query = new WP_Query(array('post_type' => 'video', 'genre' => 'scifi','actor' => 'keanureaves','posts_per_page' => -1));
//
$wp_query = new WP_Query(array('post_type' => 'video', 'genre' => 'scifi','actor' => 'keanureaves','posts_per_page' => -1));
if (have_posts()) :
     while (have_posts()) : the_post();
?>
     <div>
       <h3><a href="<?the_permalink();?>"><?=get_the_title();?></a></h3>
     </div>
     <div>
       <p><?=get_the_content();?></p>
     </div>
<?
    endwhile;
else:
?>
     <div>
       <p>No registers found.</p>
     </div>
<?
endif;
?>

That’s all folks. Copy, past and make it work. The code above was tested a lot, please let me know about any issue.
Era isso pessoal. Copiem, colem e façam acontecer. O código acima foi bastante testado, por favor me mantenham informado sobre qualquer dificuldade.
