Create a custom post type (A-Z)

Let’s say I want a custom post type that has it’s own set of categories, instead of piggy-backing off the default “posts” categories. In essence it can be like having a completely separate posts section. We do this with CUSTOM POST TYPES and custom TAXONOMIES.

<?php
 function codex_custom_init() {
	register_post_type( 'events', 
	    array(
	      'public' => true,
	      'has_archive' => true,
	      'menu_position' => 5, // PLACES NEW CUSTOM POST TYPE DIRECTLY BELOW 'POSTS' ON SIDE ADMIN NAV
	      'menu_icon' => '', // YOU CAN SET A CUSTOM ICON FOR THE SIDE MENU HERE
	      
	      // THIS SETS UP ALL YOUR LABELS AND ADD/EDIT PROMPTS
	      'labels' => array(
	        'name' => __( 'Events' ),
	        'singular_name' => __( 'Event' ),
	        'add_new' => __( 'Add New' ),
	        'add_new_item' => __( 'Add New Event' ),

		  // MAKING IT SIMILAR TO PAIRED DOWN COMPARED TO REGULAR POSTS

 }
// REGISTER CUSTOM TAXONOMIES
function event_init() {
	// create a new taxonomy
	$labels = array(

		'new_item_name'     => __( 'New Event Type Name' ),
		'menu_name'         => __( 'Event Types' ),
	);

	$args = array(
		'menu_position'	    => 1,
		'hierarchical'      => true,

		'rewrite'           => array( 'slug' => 'event-type' ),
	);
	register_taxonomy('event-type',array('events'),$args);
}

// THEN YOU INITIALIZE THE CODE BY RUNNING THE "init" HOOK
add_action( 'init', 'codex_custom_init' );
add_action( 'init', 'event_init' );
