Code

function views_ui_get_form_progress($view) {
    $progress = FALSE;
    if (!empty($view->stack)) {
        // The forms on the stack have integer keys that don't change as the forms
        // are completed, so we can see which ones are still left.
        $keys = array_keys($view->stack);
        // Add 1 to the array keys for the benefit of humans, who start counting
        // from 1 and not 0.
        $current = reset($keys) + 1;
        $total = end($keys) + 1;
