wp_register_ability_category() │ WP 6.9.0

Registers a new ability category.

Ability categories provide a way to organize and group related abilities for better discoverability and management. Ability categories must be registered before abilities that reference them.

Ability categories must be registered on the wp_abilities_api_categories_init hook.

Example:

function my_plugin_register_categories() {
	wp_register_ability_category(
		'content-management',
		array(
			'label'       => __( 'Content Management', 'my-plugin' ),
			'description' => __( 'Abilities for managing and organizing content.', 'my-plugin' ),
		)
	);
}
add_action( 'wp_abilities_api_categories_init', 'my_plugin_register_categories' );

No Hooks.

Returns

WP_Ability_Category|null. The registered ability category instance on success, null on failure.

Usage

wp_register_ability_category( $slug, $args ): ?WP_Ability_Category;

$slug(string) (required)

The unique slug for the ability category. Must contain only lowercase alphanumeric characters and dashes (e.g., 'data-export').

$args(array) (required)
