A Kohana module to help with building HTML navigation menus

HTML Navigation Module for Kohana 3.3

Simplify rendering, building and maintenance of simple, dynamic standardised navigation menus. Instead of..., _(*1)

<? if ($user->get_role() === Role::ANONYMOUS):?>
<ul>
    <li><a href="/" <?= $page === 'home' ? 'class="active"' : NULL?>>Home</a></li>
    <li><a href="/about" <?= $page === 'about' ? 'class="active"' : NULL?>>About</a></li>
</ul>
<? // elseif (...)?>

... we do this:, _(*2)

<?
return [
'items' => [
            'url'     => 'home',
            'title'   => 'Home',
        ],
        [
            'url'     => 'about',
            'title'   => 'About',
        ],
];

Basics

You define your menus in Kohana configuration files (see config/menu/navbar.php). Then, in your (main) controller (or template), you construct a new Menu object, set the active link and render it in your template. Done., _(*3)

Example use case

A WordPress type blog might have..., _(*4)

• Public main navigation menu
• Public footer menu
• Admin-only menu on the public pages, when admin is logged in
• Admin-only menu on the administrator interface

Normally, you'd build HTML views with ul and li elements and then write some PHP to highlight the active link. This is difficult to maintain (DRY) and too much hassle (not to mention ugly)., _(*5)

Instead, describe your (standardised) menus in configuration files and have Kohana do the heavy lifting., _(*6)

Installation

Place the files in your modules directory.

As a Git submodule:

git clone git://github.com/anroots/kohana-menu.git modules/menu

As a Composer dependency

{
    "require": {
        "php": ">=5.4.0",
        "composer/installers": "*",
        "anroots/menu":"2.*"
    }
}

Copy MODPATH.menu/config/menu/navbar.php into APPPATH/config/menu/navbar.php and customize

Activate the module in bootstrap.php.

<?php
Kohana::modules(array(
    ...
    'menu' => MODPATH.'menu',
));

Echo menu output in your template

<div class="navbar navbar-fixed-top">
    <div class="navbar-inner">
        <div class="container">
            <?=(string)Menu::factory('navbar')?>
        </div>
    </div>
</div>

You might wish to instantiate the menu in your main controller, since this gives you a way to interact with the Menu object before it's rendered., _(*7)

Config files

You can use different config files by setting the factory's $config parameter., _(*8)

The view key of the config files sets the view file that will be used to render the menu. It defaults to a view file based on the $config parameter: /views/templates/menu/$config and if that does not exist falls back on the included /views/templates/menu/default view file. For an example, see the included navbar.php config file., _(*9)

Example: Load menu configuration based on user role

    $menu = Menu::factory($role); // this could use `config/menu/(user|admin).php`

Marking the current menu item

Use set_current() to mark the current menu item in your controller, _(*10)

    $menu->set_current('article/show');

The parameter of set_current() is the URL value of the respective item or its (numeric) array key, _(*11)

Documentation

The code is mostly commented and more help can be found on the Wiki., _(*12)

Licence

The Kohana module started out as a fork of the original Kohana Menu module by Bastian Bräu, but is now independently developed under the MIT licence., _(*13)
