Key Methods

register(): void

Main registration method that sets up the post type and all admin hooks.

render_event_date_column($column, $post_id): void

control_taxonomy_menus(): void

Admin Menu Control

The class provides selective control over which taxonomies appear in the admin menu for the events post type. By default, only venue and promoter taxonomies are shown, with settings as an additional menu item.

This is controlled via the datamachine_events_post_type_menu_items filter:

add_filter('datamachine_events_post_type_menu_items', function($items) {
    return [
        'venue' => true,
        'promoter' => true,
        'settings' => true
    ];
});

Integration Points

• Meta Storage: Works with meta-storage.php for automatic datetime synchronization
• Taxonomies: Integrates with Venue_Taxonomy and Promoter_Taxonomy
• Blocks: Supports Event Details and Calendar blocks
• REST API: Provides REST endpoints for the post type

Admin Columns

The custom event date column shows:

• Formatted date (M j, Y format)
• Formatted time (g:i a format)
• "No date set" message when no datetime is available
• "Invalid date" message for malformed dates
