WooCommerce Admin Page Controller

Pages rendered with React and pages that include the WooCommerce Admin header (containing the Activity Panel) need to be registered with the WooCommerce Admin Page Controller.

This is the API you will use to add your own React-powered page, or to include the WooCommerce Admin header on your plugin pages.

Connecting a PHP-powered Page

To show the WooCommerce Admin header on existing PHP-powered admin pages (most plugin pages), use the wc_admin_connect_page() function.

Connecting pages uses five parameters to wc_admin_connect_page():

  • id - Identifies the page with the controller. Required.
  • parent - Denotes the page as a child of parent. Used for breadcrumbs. Optional.
  • screen_id - Corresponds to PageController::get_current_screen_id() to determine the current page. Required.
  • title - Page title. Used to build breadcrumbs. String or array of breadcrumb pieces. Required.
  • path - Page path (relative). Used for linking breadcrumb pieces when this page is a parent. Optional.

Examples

// WooCommerce > Settings > General (default tab).
wc_admin_connect_page(
	array(
		'id'        => 'woocommerce-settings',
		'screen_id' => 'woocommerce_page_wc-settings-general',
		'title'     => array(
			__( 'Settings', 'woocommerce' ),
			__( 'General', 'woocommerce' ),
		),
		'path'      => add_query_arg( 'page', 'wc-settings', 'admin.php' ),
	)
);

The WooCommerce > Settings > General example shows how to set up multiple breadcrumb pieces for a page. When building the breadcrumbs, WooCommerce will attach a link to path to the first piece in the title array. All subsequent pieces are plain text (not linked).

// WooCommerce > Settings > Payments.
wc_admin_connect_page(
	array(
		'id'        => 'woocommerce-settings-payments',
		'parent'    => 'woocommerce-settings',
		'screen_id' => 'woocommerce_page_wc-settings-checkout',
		'title'     => __( 'Payments', 'woocommerce' ),
		'path'      => add_query_arg(
			array(
				'page' => 'wc-settings',
				'tab'  => 'checkout',
			),
			'admin.php'
		),
	)
);

// WooCommerce > Orders.
wc_admin_connect_page(
	array(
		'id'        => 'woocommerce-orders',
		'screen_id' => 'edit-shop_order',
		'title'     => __( 'Orders', 'woocommerce' ),
		'path'      => add_query_arg( 'post_type', 'shop_order', 'edit.php' ),
	)
);

Determining Screen ID

WooCommerce Admin implements it's own version of get_current_screen() to allow for more precise identification of admin pages.

Some screen ID formats that the function will generate are:

  • {$current_screen->action}-{$current_screen->action}-tab-section
  • {$current_screen->action}-{$current_screen->action}-tab
  • {$current_screen->action}-{$current_screen->action} if no tab is present
  • {$current_screen->action} if no action or tab is present

WooCommerce Admin can recognize WooCommerce pages that have both tabs and sub sections. For example, woocommerce_page_wc-settings-products-inventory is the WooCommerce > Settings > Products > Inventory page.

If your plugin adds new pages with tabs and sub sections, use the wc_admin_pages_with_tabs and wc_admin_page_tab_sections filters to have WooCommerce Admin generate accurate screen IDs for them.

You can also use the wc_admin_current_screen_id filter to make any changes necessary to the behavior.

Registering a React-powered Page

Registering a React-powered page is similar to connecting a PHP page, but with some key differences. Registering pages will automatically create WordPress menu items for them, with the appropriate hierarchy based on parent.

Register pages with wc_admin_register_page() using these parameters:

  • id - Identifies the page with the controller. Required.
  • parent - Denotes the page as a child of parent. Used for breadcrumbs. Optional.
  • title - Page title. Used to build breadcrumbs. String or array of breadcrumb pieces. Required.
  • path - Page path (relative to #wc-admin). Used for identifying this page and for linking breadcrumb pieces when this page is a parent. Required.
  • capability - User capability needed to access this page. Optional (defaults to manage_options).
  • icon - Dashicons helper class or base64-encoded SVG. Include the entire dashicon class name, ie dashicons-*. This is optional and won't be included in WC Navigation.
  • position - Menu item position for parent pages. Optional. See: add_menu_page().

Example - Adding a New Analytics Report

Add our new report using the appropriate filter:

import { addFilter } from '@wordpress/hooks';

addFilter( 'woocommerce_admin_reports_list', 'my-namespace', ( reports ) => {
	reports.push( {
		report: 'example',
		title: __( 'Example', 'my-textdomain' ),
		component: ExampleReportComponent,
	} );

	return reports;
} );

Register the report page with the controller:

function add_report_menu_item( $report_pages ) {
	$report_pages[] = array(
		'id'     => 'example-analytics-report',
		'title'  => __( 'Example', 'my-textdomain' ),
		'parent' => 'woocommerce-analytics',
		'path'   => '/analytics/example',
	);

	return $report_pages;
}
add_filter( 'woocommerce_admin_report_menu_items', 'add_report_menu_item' );

Example - Adding a New WooCommerce Admin Page

Alternatively, register a regular page with the controller.

function add_extension_register_page() {
    if ( ! function_exists( 'wc_admin_register_page' ) ) {
        return;
	}

    wc_admin_register_page( array(
		'id'       => 'my-example-page',
		'title'    => __( 'My Example Page', 'my-textdomain' ),
		'parent'   => 'woocommerce',
		'path'     => '/example',
	) );
}

add_action( 'admin_menu', 'add_extension_register_page' );

Supply a React component on the client side.

import { addFilter } from '@wordpress/hooks';
import { __ } from '@wordpress/i18n';

const MyExamplePage = () => <h1>My Example Extension</h1>;

addFilter( 'woocommerce_admin_pages_list', 'my-namespace', ( pages ) => {
	pages.push( {
		container: MyExamplePage,
		path: '/example',
		breadcrumbs: [ __( 'My Example Page', 'my-textdomain' ) ],
		navArgs: {
			id: 'my-example-page',
		},
	} );

	return pages;
} );
