description

Guide for creating Custom Post Types, Taxonomies, Custom Fields, and Custom Post Statuses in Klytos CMS. Use when adding new content types beyond pages (products, properties, blog posts, events, portfolio items, etc.), adding taxonomies for content organization, defining structured custom fields with validation, or creating custom workflow statuses per post type. Covers post type structure, MCP tools, plugin API, admin interface, hooks, and complete end-to-end examples.

Klytos Custom Post Types, Taxonomies & Custom Fields

Post Type Structure

[
    'id'             => string,     // Post type ID (e.g. 'products')

    'slug'           => string,     // Base URL slug (e.g. '/products/')
    'slug_i18n'      => array,      // Localized slugs: {'es': '/productos/', 'en': '/products/'}
    'taxonomies'     => array,      // Taxonomy definitions
    'custom_fields'  => array,      // Field definitions
    'statuses'       => array,      // Custom workflow statuses (optional)
    'builtin'        => bool,       // true only for 'page'
]

Custom Statuses

Each post type can define custom workflow statuses in addition to the 4 system statuses (draft, published, scheduled, trashed).

Status Definition Structure

'statuses' => [
    [
        'id'        => 'review',        // slug, max 20 chars, cannot collide with system statuses
        'label'     => 'In Review',     // human-readable
        'color'     => '#f59e0b',       // hex color for badges
        'icon'      => 'eye',           // optional icon
        'is_public' => false,           // if true, pages built to live site like published
    ],
]
