Multilevel menu library for codefight cms

2009-05-26 13:11:35Damodar Bashyal

Codefight cms is built with the help of codeigniter cms. Last weekend i wrote a multi-level menu library. You can use it for codefight cms or wherever you want.

This may not be perfect but it works. If you have a better idea i would like to know. This is how it looks like.

<?php
//If BASEPATH is not defined, simply exit.
if (!defined('BASEPATH')) exit('No direct script access allowed');
/*
>menus_id | menus_active | menus_parent_id | menus_link
>menus_title | menu_type | menus_meta_title | menus_meta_keywords
>menus_meta_description | menus_sort

Parameters that can be passed in an array:
$parameters = array (
'ul_param' => 'class=“xyz“...',
'li_param' => '...',
'a_param' => '...',
)
