MenuBuilder Helper

A dynamic menu building helper for CakePHP

Background

This is a menu building helper with lot of customization options. Check out the Usage section.

Now it supports menus built with ACL Menu Component by Mark Story

Features

  • Generate menu based on current user type/group/permission/level (Can be used with Auth, Authsome, etc Components)
  • Provide various useful CSS class
  • Multi-level menu support
  • Supports ACL Menu Component by Mark Story
  • CakePHP Unit Test (100% Code coverage)

Requirements

  • CakePHP 2.x
  • PHP 5.3

Installation

[Using Composer]

Add the plugin to your project's composer.json - something like this:

  {
    "require": {
      "torifat/cake-menu_builder": "2.0.3"
    }
  }

Because this plugin has the type cakephp-plugin set in its own composer.json, Composer will install it inside your /Plugins directory, rather than in the usual vendors file. It is recommended that you add /Plugins/MenuBuilder to your .gitignore file. (Why? read this.)

[Manual]

[GIT Submodule]

In your app directory type:

  git submodule add -b master git://github.com/torifat/cake-menu_builder.git Plugin/MenuBuilder
  git submodule init
  git submodule update

[GIT Clone]

In your Plugin directory type:

git clone -b master git://github.com/torifat/cake-menu_builder.git MenuBuilder

Enable plugin

In 2.0 you need to enable the plugin in your app/Config/bootstrap.php file:

CakePlugin::load('MenuBuilder');

If you are already using CakePlugin::loadAll();, then this is not necessary.

Usage

Minimal Setup

Load the Plugin by modifying your app/Config/bootstrap.php

<?php
...
CakePlugin::load('MenuBuilder');
?>

or

<?php
...
CakePlugin::loadAll();
?>

To use this helper add the following to your AppController:

<?php
...
var $helpers = array(..., 'MenuBuilder.MenuBuilder');

function beforeFilter() {
    ...
    // Define your menu
    $menu = array(
        'main-menu' => array(
            array(
                'title' => 'Home',
                'url' => array('controller' => 'pages', 'action' => 'home'),
            ),
            array(
                'title' => 'About Us',
                'url' => '/pages/about-us',
            ),
        ),
        'left-menu' => array(
            array(
                'title' => 'Item 1',
                'url' => array('controller' => 'items', 'action' => 'view', 1),
                'children' => array(
                    array(
                        'title' => 'Item 3',
                        'url' => array('controller' => 'items', 'action' => 'view', 3),
                    ),
                    array(
                        'title' => 'Item 4',
                        'url' => array('controller' => 'items', 'action' => 'view', 4),
                    ),
                )
            ),
            array(
                'title' => 'Item 2',
                'url' => array('controller' => 'items', 'action' => 'view', 2),
            ),
        ),
    );

    // For default settings name must be menu
    $this->set(compact('menu'));
    ...
}
?>

Now to build your main-menu use the following code in the View:

<?php
    echo $this->MenuBuilder->build('main-menu');
?>

You'll get the following output in the Home (/pages/home) page:

<ul id="main-menu">
    <li class="first-item active"><a title="Home" href="/pages/home">Home</a></li>
    <li><a title="About Us" href="/pages/about-us">About Us</a></li>
</ul>

And to build your left-menu use the following code in the View:

<?php
    echo $this->MenuBuilder->build('left-menu');
?>

You'll get the following output in your 'Item 4' (/items/view/4) page:

<ul id="left-menu">
    <li class="first-item active has-children">
        <a title="Item 1" href="/items/view/1">Item 1</a>
        <ul>
            <li class="first-item">
                <a title="Item 3" href="/items/view/3">Item 3</a>
            </li>
            <li class="active">
                <a title="Item 4" href="/items/view/4">Item 4</a>
            </li>
        </ul>
    </li>
    <li>
        <a title="Item 2" href="/items/view/2">Item 2</a>
    </li>
</ul>

You can pass optional parameter in build function like -

<?php
    echo $this->MenuBuilder->build('main-menu', array('class' => array('fun', 'red'));
    // OR
    echo $this->MenuBuilder->build('main-menu', array('class' => 'fun green');
?>

Advance Setup

You can provide advance options in the array like the following:

<?php
...
var $helpers = array(
    ...
    'MenuBuilder.MenuBuilder' => array(/* array of settings */)
);
?>

Default Settings

if you do not provide any settings then the following settings will work.

$settings = array(
    'activeClass' => 'active',
    'firstClass' => 'first-item',
    'childrenClass' => 'has-children',
    'evenOdd' => false,
    'itemFormat' => '<li%s>%s%s</li>',
    'wrapperFormat' => '<ul%s>%s</ul>',
    'noLinkFormat' => '<a href="#">%s</a>',
    'menuVar' => 'menu',
    'authVar' => 'user',
    'authModel' => 'User',
    'authField' => 'group',
);

Settings Details

activeClass CSS classname for the selected/current item and it's successors. (default - 'active')

firstClass CSS classname for the first item of each level. (default - 'first-item')

childrenClass CSS classname for an item containing sub menu. (default - 'has-children')

evenOdd If it is set to true then even/odd classname will be provided with each item. (default - false)

<ul id="main-menu">
    <li class="first-item odd">
        <a title="Home" href="/pages/home">Home</a>
    </li>
    <li class="even">
        <a title="About Us" href="/pages/about-us">About Us</a>
    </li>
</ul>

itemFormat if you want to use other tag than li for menu items (default - '<li%s>%s%s</li>')

wrapperFormat if you want to use other tag than ul for menu items container (default - '<ul%s>%s</ul>')

noLinkFormat Format for empty link item (default - '<a href="#">%s</a>')

Example Setting

'MenuBuilder.MenuBuilder' => array(
    'itemFormat' => '<div%s>%s%s</div>',
    'wrapperFormat' => '<div%s>%s</div>',
    'noLinkFormat' => '<div>%s</div>',
),

Example Output (an extra item added to explain noLinkFormat)

<div id="main-menu">
    <div class="first-item">
        <a title="Home" href="/pages/home">Home</a>
    </div>
    <div>
        <a title="About Us" href="/pages/about-us">About Us</a>
    </div>
    <div>
        Empty
    </div>
</div>

menuVar Name of the variable that contains all menus (default - 'menu')

Following settings will be used for permission based menu (see below)

authVar Name of the variable that contains the User data (default - 'user')

authModel Name of the authentication model (default - 'User')

authField Name of the field that contains the user's type/group/permission/level (default - 'group')

Permission Based Menu

Suppose you have a users table like the following one:

CREATE TABLE `users` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `email` varchar(255) NOT NULL,
    `password` char(40) NOT NULL,
    `group` enum('user','manager','admin') NOT NULL DEFAULT 'user',
    `name` varchar(255) NOT NULL,
    PRIMARY KEY (`id`),
    UNIQUE KEY (`email`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Now suppose you are using the CakePHP auth component for authentication so add the following to your AppController:

<?php
...
function beforeFilter() {
    ...
    $user = $this->Auth->user();
    $this->set(compact('user'));
}
?>

But, If you are using Authsome component for authentication then add the following to your AppController:

<?php
...
function beforeFilter() {
    ...
    $user = Authsome::get();
    $this->set(compact('user'));
}
?>

Now we have to define permissions in our menu like this:

<?php
...
function beforeFilter() {
    ...
    // Define your menu
    $menu = array(
        'main-menu' => array(
            // Anybody can see this
            array(
                'title' => 'Home',
                'url' => array('controller' => 'pages', 'action' => 'home'),
            ),
            // Users and Admins can see this, Guests and Managers can't
            array(
                'title' => 'About Us',
                'url' => array('controller' => 'pages', 'action' => 'about-us'),
                'permissions' => array('user','admin'),
            ),
            // Only Guests can see this
            array(
                'title' => 'Login',
                'url' => array('controller' => 'users', 'action' => 'login'),
                'permissions' => array(''),
            ),
        ),
        ...
    );
    // For default settings name must be menu
    $this->set(compact('menu'));
    ...
}
?>

You're Done!

Other Menu Options

permissions Array of type/group/permission/level whose can view that item (default - array())

partialMatch Normally url matching are strict. Suppose you are in /items/details and your menu contains an entry for /items then by default it'll not set active. But if you set partialMatch to true then it'll set active . (default - false)

id Provide CSS id to the item (default - null)

class Provide CSS class to the item (default - null)

separator If you want to define some separator in your menu, below is a nice example of what you can do with it. (default - false)

Example Setting

'MenuBuilder.MenuBuilder' => array(
    'itemFormat' => '<dd%s>%s%s</dd>',
    'wrapperFormat' => '<dl%s>%s</dl>',
    'noLinkFormat' => '<dd>%s</dd>',
),

Example Menu

<?php
...
var $helpers = array(..., 'MenuBuilder.MenuBuilder');

function beforeFilter() {
    ...
    // Define your menu
    $menu = array(
        'main-menu' => array(
            array(
                'separator' => '<dt>Main Menu</dt>',
            ),
            array(
                'title' => 'Home',
                'url' => array('controller' => 'pages', 'action' => 'home'),
            ),
            array(
                'title' => 'About Us',
                'url' => '/pages/about-us',
            ),
        )
    );

    // For default settings name must be menu
    $this->set(compact('menu'));
    ...
}
?>

Example Output

<dl id="main-menu">
    <dt>Main Menu</dt>
    <dd class="first-item">
        <a title="Home" href="/pages/home">Home</a>
    </dd>
    <dd>
        <a title="About Us" href="/pages/about-us">About Us</a>
    </dd>
</dl>

More to come :)
