Huh?

The Menu library is used to create hierchical HTML structures ideal for menu systems. To keep it flexible, it does not generate the CSS and/or Javascript code for you. You have the pleasure of doing that yourself.

Why?

This library came out of a need to apply current and parent CSS styles to a menu system in a project I was working on. But the way I had it built, it couldn't be done without some hackery. So I got to work making this.

Installing

• Copy/move files into place
  • /application/config/menu.php
  • /application/libraries/Menu.php
• Done

Configuration

Still working on this section. Come back later.

Example

// Load the library
$this->load->library('menu');

// Menu structure. This could be generated or static
$menu = array(
    array(
        'uri' => '',
        'label' => 'Home'
    ),
    array(
        'uri' => 'services',
        'label' => 'Services',
        'children' => array(
            array(
                'uri' => 'services/foo/',
                'label' => 'Foo'
            ),
            array(
                'uri' => 'services/bar',
                'label' => 'Bar'
            )
        )
    ),
    array(
        'uri' => 'about',
        'label' => 'About Us'
        'children' => array(
            array(
                'uri' => 'about/team/',
                'label' => 'Team'
            ),
            array(
                'uri' => 'about/jobs',
                'label' => 'Work For Us'
            )
        )
    ),
    array(
        'uri' => 'contact',
        'label' => 'Contact'
    )
);

// Render the menu (URI based)
echo $this->menu->set_menu($menu)
    ->generate();

// Render the menu (URI based)
echo $this->menu->generate($menu);

// Render the menu (Menu based)
echo $this->menu->set_ancestry('menu')
    ->set_current('about', 'uri')
    ->generate($menu);

Methods

set_current() method

/*
 * Set currently active menu item. Only applied when 'ancestry' is set to 'menu'
 *
 * $value string to look for when applying current and ancestry status
 * $key type of element to look at (eg. 'label', 'uri')
 */

function set_current($value, $key = 'uri')...
// example
  echo $this->menu->set_current('Foo', 'label');

set_menu() method

/*
 * Set menu items
 *
 * $menu multidimensional array of menu items
 */

function set_menu($menu = array())...
// example
  $my_menu = array(
    array(
        'uri' => '',
        'label' => 'Home'
    ),
    array(
        'uri' => 'about',
        'label' => 'About Us'
        'children' => array(
                array(
                    'uri' => 'about/team',
                    'label' => 'Our Team'
                )
            )
  );
  echo $this->menu->set_menu($my_menu');

set_ancestry() method

/*
 * Set ancestry type
 *
 * $ancestry type of ancestry detection to use. Use 'path' or 'menu'
 */

function set_ancestry($ancestry = 'path')...
// example
  echo $this->menu->set_ancestry('menu');

generate() method

/*
 * Generate menu
 *
 * $menu items for the menu if not already defined
 * $config configuration values for the menu
 */

function generate($items = NULL, $config = array())...
// example
  $my_menu = array(
    array(
        'uri' => '',
        'label' => 'Home'
    ),
    array(
        'uri' => 'about',
        'label' => 'About Us'
        'children' => array(
                array(
                    'uri' => 'about/team',
                    'label' => 'Our Team'
                )
            )
  );
  echo $this->menu->generate($my_menu);

render() method

/*
 * Alias for generate(). See generate()
 */

function render($items = NULL, $config = array())...
  echo $this->menu->render();

TODO

• Turn it into a Spark!
• Flat array to multidimensional (for SQL results)
• Verify GET params work when generating ancestry. Optionaly look at GET params when checking for current, parent, ancestor
• Generate JSON result?
