#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>

I ended up with this. An optional method can be passed.

<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
if(!function_exists('active_link')) {
  function activate_menu($controller, $function = null) {
    $CI = get_instance();
    $class = $CI->router->fetch_class();
    if($function) {
        $method = $CI->router->fetch_method();
        return ($method == $function && $class == $controller) ? 'active' : '';
    }
    
    return ($class == $controller) ? 'active' : '';
  }
}?>

Hi all, i changed it with to array compatible.

<php 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();
        $is_active = FALSE;
        if(is_array($controller)) {
            foreach ($controller as $cont){
               if($cont == $class){
                   $is_active = TRUE;
               }
            }
        }else{
            if($controller == $class){
                $is_active = TRUE;
            }
        }

        return ($is_active) ? "active" : "";
    }
}?>

Yo can also set active class to top menu like this

<?=activate_menu('controller');?>
<?=activate_menu(['controller1', 'controller2']);?>

Hi all,
I think it is most easy to track active link by current url with js. Check the following link
