Sitemap Class

Search Engine Sitemap Class

---

The Sitemap class is a specialized utility in GeniXCMS designed to automate the generation of XML-compliant Sitemaps. This functionality is critical for modern SEO, as it provides search engine crawlers with a structured map of your site's content, ensuring all posts, pages, and module-specific resources are indexed accurately.

⚡ Index & Map Generation

GeniXCMS supports both individual content maps and master sitemap indexes for larger installations.

Sitemap::createIndex()

Generates a master Sitemap Index file. This is the primary entry point for search engine crawlers (e.g., sitemap.xml).

• Logic: It dynamically lists available content-type sitemaps (Posts, Pages, Categories).
• Format: Directly streams XML with the Content-Type: text/xml header.

Sitemap::create(string $type, ...)

Generates an individual content-specific map list.

Parameter	Type	Default	Description
$type	string	'post'	The specific content type to include (e.g., post, page).
$limit	int	20	Maximum number of items in the XML feed.
$url_method	string	'post'	The Url Class method used for link generation.

// Typically executed within a sitemap controller or dedicated route
Sitemap::create('post', 100, 'post');

🏗️ Technical Architecture

The Sitemap class performs automated data transformations to ensure XML compliance and SEO efficacy.

1. Metric Acquisition: Fetches recent content updates using the Posts Class.
2. Metadata Injection:
   • lastmod: Automatically calculates the last modification date based on the post timestamp.
   • changefreq: Defaults to daily to encourage frequent re-crawling.
   • priority: Assigns relative priority to different content types (Home > Post > Category).
3. Link Resolution: Uses the Url Class to ensure all links are absolute permalinks, including Smart URL support.

🔌 Extensibility: Registering Custom Maps

Modules can register their own custom content types into the sitemap engine using the Sitemap::addMap() method.

// Registering a Custom Product Module Sitemap
$new_map = [
    'product' => [
        'class' => 'ProductUrl', // The class handling the URL logic
        'url'   => 'detail'      // The specific method to call
    ]
];
Sitemap::addMap($new_map);
