Navi

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 >= 7.0

Installation

Bedrock (or Sage)

Install via Composer:

$ composer require log1x/navi

Manual

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

Usage

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

Basic Usage

<?php

use Log1x\Navi\Navi;

$navigation = (new Navi())->build('primary_navigation');

if ($navigation->isEmpty()) {
  return;
}

return $navigation->toArray();

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

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

Optionally, you may pass a key and default to call a specific object key with a fallback have it be null, empty, or not set.

$navigation->get()->name;
$navigation->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.

# Blade
{{ get_post_type($item->objectId) }}

# PHP
<?php echo 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.

# Blade
{{ get_field('custom_nav_label', $item->id) ?: $item->label }}

# PHP
<?php echo get_field('custom_nav_label', $item->id) ?: $item->label; ?>

Example Output

When calling build(), Navi will parse the passed navigation menu and return a fluent container containing your menu items. To return an array of objects, simply call ->toArray().

By default, build() calls primary_navigation which is the default menu theme location on Sage.

array [
  5 => {
    +"active": true
    +"activeAncestor": false
    +"activeParent": false
    +"children": false
    +"classes": "example"
    +"dbId": 5
    +"description": false
    +"id": 5
    +"label": "Home"
    +"objectId": "99"
    +"parent": false
    +"slug": "home"
    +"target": "_blank"
    +"title": false
    +"url": "https://sage.test/"
    +"xfn": false
  }
  6 => {
    +"active": false
    +"activeAncestor": false
    +"activeParent": false
    +"children": array [
      7 => {
        +"active": false
        +"activeAncestor": false
        +"activeParent": false
        +"children": array [
          ...
        ]
        +"classes": false
        +"dbId": 7
        +"description": false
        +"id": 7
        +"label": "Example"
        +"objectId": "101"
        +"parent": 6
        +"slug": "example"
        +"target": false
        +"title": false
        +"url": "#"
        +"xfn": false
      }
    ]
    +"classes": false
    +"dbId": 6
    +"description": false
    +"id": 6
    +"label": "Sample Page"
    +"objectId": "100"
    +"parent": false
    +"slug": "sample-page"
    +"target": false
    +"title": false
    +"url": "https://sage.test/sample-page/"
    +"xfn": false
  }
]

That being said, depending on how deep your menu is– you can ultimately just keep looping over ->children indefinitely.
