hey colins,
i did something similar with colorbox [similar tool]. it works and may be helpful for ideas.
in the template:
replace the 1-line the php echo $output with these 2 lines:
$output.='<script>$("a.crud-action").colorbox({iframe:true,width:"98%",height:"98%"}); </script> ';
echo $output;
add the css and js you need at the end of the head section -- something like this:
<link rel="stylesheet" href="js/colorbox.css" />
<script src="//cdn.jsdelivr.net/colorbox/1.3.32/jquery.colorbox-min.js"></script>
my controller is like this:
public function employees()
{
$crud = new grocery_CRUD();
$crud->set_table('employees');
$crud->add_action('Visit Steve Thurber', 'http://www.grocerycrud.com/assets/uploads/general/smiley.png' '', '', array($this,'visitSteveThurber'));
$this->load->view('template.php',$output);
}
function visitSteveThurber($primary_key , $row)
{
return 'http://dl.dropbox.com/u/4130873/it.html';
}
