Question

I have a custom library (in application\libraries) which I can call fine, however I want to pass data from model, via the controller:
In the controller:

$MenuData['daily']  = $this->bookmarks_model->getDaily();

$this->load->library('MyMenu');

$menu = new MyMenu;

$data['menu'] = $menu->ShowMenu($MenuData);

In the MyMenu library:

function ShowMenu($Params)
{
$CI =& get_instance();
$CI->load->helper('url');
$CI->config->item('base_url');
//More Code  here  
$menu .= "<li><a href='#'>Daily</a>";
$menu .= "  <ul>";
foreach($daily as $row) : 
    $menu .= "<li><a href='" .  $row->url . "' target='_blank'>" .  $row->short_title . "</a></li>";
endforeach; 
$menu .= "   </ul> ";
$menu .= "   </li>";
//More Code  here  
}
return $menu;

However I’m getting an undefined variable error and invalid arguments for for each.
Any help greatly appreciated!

You are passing a multi-dimensional array ($MenuData)to the function, then trying to pass one of the second level arrays ($MenuData['daily']) inside the MD array to the foreach loop without referencing the first level. Instead of :

foreach($daily as $row) :

Try:

foreach($Params['daily'] as $row) :

Or before your foreach loop declare a variable to hold the second level array:

$daily = $Params['daily']
foreach($daily as $row):
