Hate the WordPress NavWalker? Me too.

Navi is a developer-friendly alternative to the NavWalker. Easily build your WordPress menus using an iterable object inside of a template/view.

Requirements

• PHP >= 8.0

Installation

Bedrock (or Sage)

Install via Composer:

$ composer require log1x/navi

Manual

Download the latest release .zip and install into wp-content/plugins.

Usage

Building your menu can be done by passing your menu location to Navi::make()->build():

use Log1x\Navi\Navi;

$menu = Navi::make()->build('primary_navigation');

By default, build() uses primary_navigation if no menu location is specified.

Retrieving an array of menu items can be done using all():

if ($menu->isNotEmpty()) {
    return $menu->all();
}

Note

Check out the examples folder to see how to use Navi in your project.

Menu Item Classes

By default, Navi removes the default WordPress classes from menu items such as menu-item and current-menu-item giving you full control over your menu markup while still passing through custom classes.

If you would like these classes to be included on your menu items, you may call withDefaultClasses() before building your menu:

$menu = Navi::make()->withDefaultClasses()->build();

In some situations, plugins may add their own classes to menu items. If you would like to prevent these classes from being added, you may pass an array of partial strings to withoutClasses() match against when building.

$menu = Navi::make()->withoutClasses(['shop-'])->build();

Accessing Menu Object

When building the navigation menu, Navi retains the menu object and makes it available using the get() method.

By default, get() returns the raw wp_get_nav_menu_object() allowing you to access it directly.

$menu->get()->name;

Optionally, you may pass a key and default to call a specific object key with a fallback when the value is blank:

$menu->get('name', 'My menu title');

Accessing Page Objects

If your menu item is linked to a page object (e.g. not a custom link) – you can retrieve the ID of the page using the objectId attribute.

Below is an example of getting the post type of the current menu item:

$type = get_post_type($item->objectId)

Accessing Custom Fields

In a scenario where you need to access a custom field attached directly to your menu item – you can retrieve the ID of the menu item using the id attribute.

Below we'll get a label override field attached to our menu using ACF – falling back to the default menu label if the field is empty.

$label = get_field('custom_menu_label', $item->id) ?: $item->label;

Acorn Usage

If you are using Navi alongside Acorn (e.g. Sage), you may generate a usable view component using Acorn's CLI:

$ wp acorn navi:make Menu

Once generated, you may use the view component in an existing view like so:

<x-menu name="footer_navigation" />

To list all registered locations and their assigned menus, you can use the list command:

$ wp acorn navi:list

Example Output

When calling build(), Navi will retrieve the WordPress navigation menu assigned to the passed location and build out an array containing the menu items.

An example of the menu output can be seen below:

array [
  5 => {
    +"active": true
    +"activeAncestor": false
    +"activeParent": false
    +"classes": "example"
