README

The Fulcrum Custom Taxonomy Module makes your job easier for adding custom taxonomies to your project. Pass it a configuration and it handles the rest for you.

Features

• Registration is handled for you.
• Label generation - handy when you do not need internationalization.
• Stores in Fulcrum's Container - when added, automatically stores it in the Container for global usage.

Installation

The best way to use this component is through Composer:

composer require wpfulcrum/taxonomy

Dependencies

This module requires:

• at least PHP 5.6
• WordPress 4.8+

Configuring a Custom Taxonomy

This module, as with all Fulcrum modules, is configuration driven as part of the ModularConfig design pattern. In your theme/plugin's configuration folder, you will want to create a configuration file. Here is the basic structure of that file:

<?php

$config = [
    'autoload'     => true,
    'taxonomyName' => 'genre',
    'config'       => [
        'taxonomyConfig' => [],
        'labelsConfig'   => [],
    ],
];

$config['config']['taxonomyConfig'] = [
    'objectType' => ['book'],

    /**
     * Arguments Configuration Parameters
     *
     * @see https://codex.wordpress.org/Function_Reference/register_taxonomy#Arguments for more details.
     *
     * Don't configure the label or labels here.  Those are handled separately below.
     */
    'args'       => [
        'description'       => 'Book Genres',
//        'label'        => '', <- This isn't needed.
//        'labels'       => [], <- don't configure here as they are configured below.
        'hierarchical'      => true,
        'show_ui'           => true,
        'show_admin_column' => true,
        'query_var'         => true,
    ],
];

/**
 * Labels Builder - Configuration Parameters
 */
$config['config']['labelsConfig'] = [

    /***************************************************************************************************
     * When Your Plugin Doesn't Need Internationalization:
     *
     * By default, the label builder automatically builds the labels for you using the plural and singular
     * names you configure below.
     **************************************************************************************************/
    'useBuilder'   => true, // set to false when you need internationalization.
    'pluralName'   => 'Genres',
    'singularName' => 'Genre',

    /***************************************************************************************************
     * Specify the labels you want here.
     *
     * When not using the automatic builder (i.e. when 'useBuilder' is set to `false`), then you specify
     * all the custom labels here.
     *
     * If you are using the builder, any labels you specify here will overwrite what the builder generates.
     *
     * @see https://codex.wordpress.org/Function_Reference/register_taxonomy#Arguments for more details.
     **************************************************************************************************/
    'labels'       => [
        'name'              => _x('Genres', 'taxonomy general name', 'textdomain'),
        'singular_name'     => _x('Genre', 'taxonomy singular name', 'textdomain'),
        'search_items'      => __('Search Genres', 'textdomain'),
        'all_items'         => __('All Genres', 'textdomain'),
        'parent_item'       => __('Parent Genre', 'textdomain'),
        'parent_item_colon' => __('Parent Genre:', 'textdomain'),
        'edit_item'         => __('Edit Genre', 'textdomain'),
        'update_item'       => __('Update Genre', 'textdomain'),
        'add_new_item'      => __('Add New Genre', 'textdomain'),
        'new_item_name'     => __('New Genre Name', 'textdomain'),
        'menu_name'         => __('Genre', 'textdomain'),
    ],
];

return $config;

Making It Work

There are 2 ways to utilize this module:

1. With the full Fulcrum plugin.
2. Or on its own without Fulcrum.

With Fulcrum

In Fulcrum, your plugin is an Add-on. In your plugin's configuration file, you will have a parameter for the serviceProviders, where you list each of the service providers you want to use. In this case, you'll use the provider.taxonomy.

For example, using our Book Genre configuration above, this would be the configuration:

	'serviceProviders' => [

		/****************************
		 * Custom Post Types
		 ****************************/
		'genre.taxonomy' => array(
			'provider' => 'provider.taxonomy', // this is the service provider to be used.
			'config'   => BOOK_PLUGIN_DIR . 'config/taxonomy/genre.php', // path to the genre's taxonomy configuration file.
		),
	],

Fulcrum's Add-On Module handles flushing the rewrites upon plugin activation and deactivation. That saves you time.

Without Fulcrum

Without Fulcrum, you'll need to instantiate each of the dependencies and Taxonomy. For example, you would do:

$config = require_once BOOK_PLUGIN_DIR . 'config/taxonomy/genre.php';  // path to the genre's taxonomy configuration file.

$taxonomy = new PostType(
    $config['taxonomyName'],
    ConfigFactory::create($config['config']['taxonomyConfig']),
    new LabelsBuilder(ConfigFactory::create($config['config']['labelsConfig']))
);
$taxonomy->register();    

You will need to handle flushing the rewrites with your plugin's activation and deactivation.
