Question

I have built an app using the facebook canvas method. This works in Mozilla but not in IE. The problem is with a breadcrumbs feature I have using PHP sessions. In IE the session is not remembered and the breadcrumb array is overwritten each time instead of appending to the array.

session_start();

//get current selected category and add to breadcumbs array
if (isset($_GET['cat_parent_id'])){
    $cat_parent_id = $_GET['cat_parent_id'];
    $cat_name = $_GET['cat_name'];
    if ($cat_parent_id == 0){
        $_SESSION['breadcrumbs'] = '';
    } else {
        //if selected category already in breadcrumb array, remove breadcrumbs after that category
        $position = array_search($cat_parent_id, array_keys($_SESSION['breadcrumbs']));
        // If a position is found, splice the array.
        if ($position !== FALSE) {
            //if ($position == 0){ $position = 1; }
            array_splice($_SESSION['breadcrumbs'], ($position + 1));
        } else {
            $_SESSION['breadcrumbs'][$cat_parent_id] = $cat_name;
        }
    }
} else {
    $cat_parent_id = 0;
    $cat_name = '';
    $_SESSION['breadcrumbs'] = '';
}

Can anyone help?
