README

A Charcoal package for generating a sitemap.

Installation

composer require charcoal/contrib-sitemap

Setup

For Charcoal projects, the package can be registered in two ways.

Charcoal Module

The Sitemap's module will register the service provider (see below) and the route (/sitemap.xml).

The module can be registered from your configuration file:

"modules": {
    "charcoal/sitemap/sitemap": {}
}

Charcoal Service Provider

The Sitemap's service provider will register the necessary services (see below) for building a sitemap.

The service provider can be registered from your configuration file:

{
    "service_providers": {
        "charcoal/view/service-provider/view": {}
    }
}

To register a route from your configuration file:

{
    "routes": {
        "actions": {
            "sitemap.xml": {
                "route": "/sitemap.xml",
                "methods": [ "GET" ],
                "controller": "charcoal/sitemap/action/sitemap",
                "action_data": {
                    "sitemap_ident": "xml"
                }
            }
        }
    }
}

By default, the action controller will look for a sitemap hierarchy named xml which can be changed via the sitemap_ident controller setting.

Overview

Routes

• GET /sitemap.xml — A route assigned to Charcoal\Sitemap\Action\SitemapAction.
  Used to serve the XML document.

Services

• charcoal/sitemap/builder — Instance of Charcoal\Sitemap\Service\Builder.
  Used to generate the collections of links from the configured models.
• sitemap/formatter/xml — Instance of Charcoal\Sitemap\Service\XmlFormatter.
  Used to generate the XML from one or more collections of links from the Builder.
• sitemap/presenter — Instance of Charcoal\Sitemap\Service\SitemapPresenter.
  Used to resolve model transformations.
• sitemap/transformer/factory — Instance of Charcoal\Factory\GenericFactory (charcoal/factory).
  Used to resolve object transformers from object types.

Configuration

The Sitemap can be configured from the application configset under the sitemap key. You can setup which objects to be included and available translations (l10n).

Most options are renderable by objects using your application's chosen template syntax (Mustache used in examples below).

Default Options

{
    /**
     * The service's configuration point.
     */
    "sitemap": {
        /**
         * One or more groups to customize how objects should be processed.

         */

             *   (see `locales.languages`).
             * - `false` — Unilingual. Include only the default language

                }
            }
        }
    }
}

Each model can override the following options of their group: l10n, locale, check_active_routes, relative_urls.

Example

The example below, identified as footer_sitemap, is marked as multilingual using the l10n option which will include all translations.

{
    "sitemap": {
        "footer_sitemap": {
            "l10n": true,
            "check_active_routes": true,
            "relative_urls": false,
            "transformer": "charcoal/sitemap/transformer/routable",
            "objects": {
                "app/object/section": {
                    "transformer": "\\App\\Transformer\\Sitemap\\Section",
                    "label": "{{ title }}",
                    "url": "{{ url }}",
                    "filters": {
                        "active": {
                            "property": "active",
                            "value": true
                        }
                    },
                    "data": {
                        "id": "{{ id }}",
                        "metaTitle": "{{ metaTitle }}"
                    },
                    "children": {
                        "app/object/section-children": {
                            "condition": "{{ isAnObjectParent }}"
                        }
                    }
                }
            }
        }
    }
}

Usage

Using the builder

The builder returns only an array. You need to make your own converter if you need another format.

Given the settings above:

$builder = $container['charcoal/sitemap/builder'];
// 'footer_sitemap' is the ident of the settings you want.
$links = $builder->build('footer_sitemap');

You can also use the SitemapBuilderAwareTrait, which includes the setter and getter for the sitemap builder, in order to use it with minimal code in every necessary class.

XML Formatter

The XML formatter generates a valid XML sitemap from the array returned by the builder.

$builder = $container['charcoal/sitemap/builder'];
$links   = $builder->build('footer_sitemap');

$formatter = $container['sitemap/formatter/xml'];
$sitemap   = $formatter->createXmlFromCollections($links);

Development

To install the development environment:

composer install

To run the scripts (PHP lint, PHPCS, PHPStan, and PHPUnit):

composer lint
composer test
