#Add active class to menu in codeigniter

In codeigniter, it’s very easy to add active class to the current menu in menu item.

Follow the below steps.

Step 1:- Create a file called "menu_helper.php" inside "application/helpers/menu_helper.php" and paste the below code.

<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
if(!function_exists('active_link')) {
  function activate_menu($controller) {
    // Getting CI class instance.
    $CI = get_instance();
    // Getting router class to active.
    $class = $CI->router->fetch_class();
    return ($class == $controller) ? 'active' : '';
  }
}?>

Step 2:- Load above helper in your controller (go to controllers/yourcontrooller.php). OR Load above helper in .autoload (go to config/autoload.php and add below code).

$this->load->helper('menu');

Step 3 :-. Add class to your menu. pass your controller name in activate_menu() method.

<li class="<?php echo activate_menu('home'); ?>"><a href="<?php echo site_url();?>">Home</a></li>
<li class="<?php echo activate_menu('aboutus'); ?>"><a href="<?php echo site_url('aboutus');?>">About us</a></li>
