IF you are using the graph api then you can follow these steps after creating the object of facebook

//Facebook Authentication part
    $session = $facebook->getSession();
    $loginUrl = $facebook->getLoginUrl(
            'canvas'    => 1,
            'fbconnect' => 0,

    $fbme = null;

    if (!$session) {
    else {
        try {
            $uid      =   $facebook->getUser();

        } catch (FacebookApiException $e) {

Add new permission in 'req_perms' parameter It will automatically redirect user to get new permissions You can check the related tutorial here http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development/
