Register Custom Post Types

I was sick of repeating myself when making CPTs. This is a pretty simple function that makes it easier.

add_action('init', 'register_cpts');
	
function register_cpts() {
      $heros = array('name'=>'Hero', 'icon' => 'dashicons-awards','position' => 4);
	jb_register_cpt($heros);
}

// register a custom post type: ex: jb_register_cpt(array('name' => 'FAQ', 'icon' => 'dashicons-format-status', 'position' => 5, 'is_singular' => true));
function jb_register_cpt($cpt_array = array()){
	$default_cpt = array( 'name' => '', 
			'icon' => 'dashicons-admin-post', 
			'position' => 4, 
			'description' => '', 
			'is_singular' => false, 
			'exclude_from_search' => false,
			'supports' => array('title','editor','thumbnail','page-attributes'),
			'taxonomies' => array(),
			'has_archive' => false,
			'rewrite' => array(),
			'public' => true,
		);	
	if(! empty($cpt_array)){
		$cpt_array = wp_parse_args( $cpt_array, $default_cpt );
		$slug = strtolower($cpt_array['name']);
		$plural = (substr($slug, -1) == 's') ? 'es' : 's';
		
		if(substr($slug, -1) == 'y'){
			$slug = rtrim($slug, 'y');
			$plural = 'ies';
		}
			
		$plural_slug = ($cpt_array['is_singular']) ? $slug : $slug.$plural;
		$plural_slug = str_replace(" ", "-", $plural_slug);
		$label = ucwords(str_replace("-", " ", $cpt_array['name']));

		$is_y = false;
		if(substr($label, -1) == 'y' && ! $cpt_array['is_singular']){
			$label = rtrim($label, 'y');
			$is_y = true;
		}

		$plural_label = ($cpt_array['is_singular']) ? $label : $label.$plural;
			
		//we removed the y from the label to put on an ies...now let's add the Y back.
		if($is_y){
			$label .= 'y';
		}

		register_post_type( $plural_slug, array(
							'label' => $plural_label,
							'description' => $description,
							'public' => $cpt_array['public'],
							'show_ui' => true,
							'show_in_menu' => true,
							'exclude_from_search' => $cpt_array['exclude_from_search'],
							'capability_type' => 'post',
							'map_meta_cap' => true,
							'hierarchical' => true,
							'rewrite' => $cpt_array['rewrite'],
							'query_var' => true,
							'taxonomies' => $cpt_array['taxonomies'],
							'menu_position' => $cpt_array['position'],
							'menu_icon' => $cpt_array['icon'],
							'supports' => $cpt_array['supports'],
							'labels' => array (
								'name' => $plural_label,
								'singular_name' => $label,
								'menu_name' => $plural_label,
								'add_new' => 'Add '.$label,
								'add_new_item' => 'Add New '.$label,
								'edit' => 'Edit',
								'edit_item' => 'Edit '.$label,
								'new_item' => 'New '.$label,
								'view' => 'View '.$plural_label,
								'view_item' => 'View '.$label,
								'search_items' => 'Search '.$plural_label,
								'not_found' => 'No '.$plural_label.' Found',
								'not_found_in_trash' => 'No '.$plural_label.' Found in Trash',
								'parent' => 'Parent '.$label
							)
						)); 
	}
}

add_action('init', 'register_cpts');

function register_cpts() {

$heros = array('name'=>'Hero', 'icon' => 'dashicons-awards','position' => 4);

jb_register_cpt($heros);

}

// register a custom post type: ex: jb_register_cpt(array('name' => 'FAQ', 'icon' => 'dashicons-format-status', 'position' => 5, 'is_singular' => true));

));

}

Now this is obviously not a “One Size Fits All” Solution but I find it helpful as a starting point.
