Custom Post Types

Herbert doesn't do anything to abstract how you would add a custom post type. This may change in the future but now you can use the standard WordPress way. You will find a file app/customPostTypes.php which is a sample of where you could define a CPT. This file is flat file which you can read more about in the config section.

CPTs the WordPress way

It's worth reading the official documentation on CPTs if your not familiar. Two other great sources are a guide by Smashing Magazine and CPT generator from Generate WP. Below is an example of an Event CPT.

// Register Custom Post Type
function event_cpt() {

    $labels = [
        'name'                => _x( 'Events', 'Post Type General Name', 'text_domain' ),
        'singular_name'       => _x( 'Event', 'Post Type Singular Name', 'text_domain' ),
        'menu_name'           => __( 'Event', 'text_domain' ),
        'name_admin_bar'      => __( 'Event', 'text_domain' ),
        'parent_item_colon'   => __( 'Parent Event:', 'text_domain' ),
        'all_items'           => __( 'All Events', 'text_domain' ),
        'add_new_item'        => __( 'Add New Event', 'text_domain' ),
        'add_new'             => __( 'Add New', 'text_domain' ),
        'new_item'            => __( 'New Event', 'text_domain' ),
        'edit_item'           => __( 'Edit Event', 'text_domain' ),
        'update_item'         => __( 'Update Event', 'text_domain' ),
        'view_item'           => __( 'View Event', 'text_domain' ),
        'search_items'        => __( 'Search Events', 'text_domain' ),
        'not_found'           => __( 'Not found', 'text_domain' ),
        'not_found_in_trash'  => __( 'Not found in Trash', 'text_domain' ),
    ];
    $rewrite = [
        'slug'                => 'event',
        'with_front'          => true,
        'pages'               => true,
        'feeds'               => true,
    ];
    $args = [
        'label'               => __( 'event', 'text_domain' ),
        'description'         => __( 'List of Events', 'text_domain' ),
        'labels'              => $labels,
        'supports'            => array( ),
        'taxonomies'          => array( 'category', 'post_tag' ),
        'hierarchical'        => false,
        'public'              => true,
        'show_ui'             => true,
        'show_in_menu'        => true,
        'menu_position'       => 5,
        'show_in_admin_bar'   => true,
        'show_in_nav_menus'   => true,
        'can_export'          => true,
        'has_archive'         => true,
        'exclude_from_search' => false,
        'publicly_queryable'  => true,
        'rewrite'             => $rewrite,
        'capability_type'     => 'page',
    ];
    register_post_type( 'event', $args );

}

// Hook into the 'init' action
add_action( 'init', 'event_cpt', 0 );

Using a Package

If you want a different way of doing it you could always use Composer to pull in a package (maybe write your own package), for example lets pull in:

https://github.com/jjgrainger/wp-custom-post-type-class

Open your composer.json and under require add:

"jjgrainger/wp-custom-post-type-class": "dev-master"

Run composer install and now you could create a CPT like so:

$people = new CPT([
    'post_type_name' => 'person',
    'singular' => 'Person',
    'plural' => 'People',
    'slug' => 'people'
]);

Organise

The logic for CPTs can be pretty large and having it in all one file would most likely be difficult to manage. An example of how you manage this a little better - it's assume we have three CPTs: People, Books and Events.

Let create a folder for our CPTs.

app/CustomPostTypes

And lets create a file for People.

app/CustomPostTypes/People.php

<?php namespace MyPlugin\CustomPostTypes;

class People {

  public function register()
  {
    \add_action( 'init', function()
    {
      $labels = [...];
      $rewrite = [...];
      $args = [...];
      \register_post_type('people', $args);
    }
    ,0);
  }
}

We'd repeat for the other two CPTs so our folder would have:

app/CustomPostTypes/
  People.php
  Books.php
  Events.php

Then in app/customPostTypes you could do

<?php

/** @var  \Herbert\Framework\Application $container */

use MyPlugin\CustomPostTypes\People;
use MyPlugin\CustomPostTypes\Books;
use MyPlugin\CustomPostTypes\Events;

// Register People CPT
(new People)->register();

// Register Books CPT
(new Books)->register();

// Register Events CPT
(new Events)->register();
