I ended up using a lightbox to create a popup - but this also worked to find the browser..
See this thread for more options...
http://us2.php.net/manual/en/function.get-browser.php#88923
Add to the Page.php below the class
class Page_Controller extends ContentController {
function get_user_browser()
{
$u_agent = $_SERVER['HTTP_USER_AGENT'];
$ub = '';
if(preg_match('/MSIE/i',$u_agent))
{
$ub = "ie";
}
return $ub;
}
Then in the template...
<% if get_user_browser == ie %>
Do something for IE
<% else %>
Else do something for all others
<% end_if %>
Hope this helps someone
