CodeIgniter + Ion Auth: Recursive menu item with access level

Question

Creating CMS with CodeIgniter and for authentication I am using Ion Auth.

Here I am trying to create recursive admin menu based on access level (user group) defined in Ion AUth db group table.

I have 3 groups syste_admin, Managers and Human Resource I want to set access to the menu so only user who has access can see such menu item.

Array defining menu items

$menu = array(
    'dashboard' => array(
        'display' => 'Dashboard',
        'url' => 'admin/dashboard',
        'iconclass' => 'fa fa-home',
        'attributes' => 'class="hellow-atts"',
        'access' => array('system_admin','managers', 'hr')
    ),
    'employee' => array(
        'display' => 'Employee',
        'url' => 'admin/hr',        
        'iconclass' => false,
        'access' => array('system_admin','hr'),
        'sub' => array(
            'manage' => array('display' => 'Manage All'),
            'add_new' => array('display' => 'Add New'),
            'access' => array('system_admin','hr'),
        ),
    ),
    'links' => array(
        'display' => 'Recommended Links',
        'iconclass' => 'fa fa-th',
        'access' => array('system_admin'),
    ),    
    'contact' => array(
        'display' => 'Contact Us',
        'access' => array('system_admin'),
    ),
    'part' => array('display' => '', 'divider' => true, 'url' => '#'),
);


echo '<nav id="page-leftbar" role="navigation">';
echo admin_side_menu($menu);
echo '</nav>';

Menu Helper function

if ( ! function_exists('admin_side_menu'))
{
    function admin_side_menu($menu_array, $is_sub=FALSE, $attributes=FALSE, $iconclass=FALSE, $divider=FALSE)
    {
        $CI =& get_instance();

        $attr = (!$is_sub) ? ' id="sidebar" class="acc-menu"' : ' class="acc-menu"';
        $menu = "<ul$attr>"; // Open the menu container

        /*
        * I want to check here if user is in defined
        * access group than s/he will be elligable to
        * access the menu else it won't display
        */        

        // this is to test if getting $access
        // however finally I want to wrap this
        // condition to the list item to make
        // it works with the access levele

        if($CI->ion_auth->in_group($access)) {
            echo 'You have access';
        } else {
            echo 'You don\'t have access';
        } //end if/else

        foreach($menu_array as $id => $properties) {

           echo '<pre>', print_r($properties), '</pre>';

            foreach($properties as $key => $val) {

                if(is_array($val))
                {
                    $sub = admin_side_menu($val, TRUE);
                }

                else
                {
                    $sub = NULL;
                    $$key = $val;
                }
            }

            if(!isset($url)) {
                $url = $id;
            }

            $lclass = ($divider) ? ' class="divider"' : '';
            $icon = (isset($iconclass)) ? '<i class="'.$iconclass.'"></i>' : '';
            $item = (!$divider) ? anchor($url, $icon.'<span>'.$display.'</span>', $attributes).$sub : '';
            $menu .= '<li'.$lclass.'>'.$item.'</li>';

            unset($url, $display, $sub);

        } // end foreach

        return $menu . "</ul>";
    }
}

With about code I am getting errors like Invalid argument supplied for foreach , Undefined variable: display, Undefined variable: sub etc..

This is may be because I am not calling access properly or don't know what is wrong. I am not so much expert and first time creating recursive menu with group permission.

Can anyone tell me how can I use and set array for access so I can check it throughout menu including sub-levels and display as per the access level defined.

Okay no one helped here but I found the answer..

Function

if ( ! function_exists('admin_side_menu'))
{

    function admin_side_menu($menu_array) {

        $CI =& get_instance();

        echo '<ul>'; // Open the menu container

        //go through each top level menu item
        foreach($menu_array as $item) {

            $admin_group = $CI->config->item('admin_group', 'ion_auth');            

            $item['access'] = array_key_exists('access', $item) ? $item['access'] : $admin_group;

            if($CI->ion_auth->in_group($item['access'])){  

                echo '<li><a href="'.$item['link'].'"">'.$item['label'].'</a>';
                //see if this menu has children
                if(array_key_exists('children', $item)) {
                    echo '<ul>';
                    //echo the child menu
                    admin_side_menu($item['children']);
                    echo '</ul>';
                }
                echo '</li>';

            }// end if
        } // end foreach

        echo '</ul>';
    }

}

Setting up in view

$menu = array(

    array(

        'label' => 'Dashboard',
        'link' => 'admin/dashboard',
        'access' => array('system_admin', 'hr', 'guest'),
        'children' => array(
            array(
                'label' => 'Admin Can See',
                'link' => 'http://google.com',
                'access' => array('system_admin', 'hr', 'guest'),
            ),
            array(
                'label' => 'Guest Can See',
                'link' => 'http://google.com',
                'access' => array('system_admin', 'hr', 'guest'),
            )
        )
    ),        
);

echo '<nav id="page-leftbar" role="navigation">';
echo admin_side_menu($menu);
echo '</nav>';

Thanks a lot... :))
