Sample public-facing page / Front-end can be found at: yoursite.com/categories, you may want to look at the index.php in the module's 'views' folder to see how to work with menus and categories in your front-end pages.

Displaying Navigation in Your Pages

The Categories module comes with the helper file which can be used in your controller or view file. The code to load the helper is:

$this->load->helper('categories/categories');

The following functions are available:

list_all_menus() - get the list of menus as an array of objects or empty array if no menu's found

list_menu_categories($id) - *get full navigation for a given menu 'id' ($id is required) - the id parameter for the menu. The function will return an array of category objects (in case navigation have nested categories the function will return the tree object)

find_a_category($id, $name) - find a category by it's 'id' or 'name' field (at least one of parameters is required) The function will return a category object if the id or name param matches an existing category, otherwise return false.

Below is the code snipplet that shows how you can easily handle nested menus on the front-end:

function build_nested_menu($categories, $outstring="") {
	if(empty($categories)) return $outstring;
	$outstring .= '<ul> ';
	foreach($categories as $cat) {
		$outstring .= '<li><a href="'.$cat->url.'">'.$cat->name.'</a> ';
			if(isset($cat->nodes)) 
				return build_nested_menu($cat->nodes, $outstring) .'</ul> ';
		$outstring .= '</li> ';
	}
	$outstring .= '</ul> ';
	return $outstring;
} 

// Load categories helper
$this->load->helper('categories/categories');

// Loop thru all menus
foreach(list_all_menus() as $menu) {
	echo build_nested_menu(list_menu_categories($menu->id));
}
