限制申请邀请 - Facebook

Question

我有一个代码，可以自动邀请用户参加我在接受应用程序后创建的活动，但它会自动邀请他们的所有朋友，是否有可能的方法来限制它邀请的朋友数量，而不是每次都邀请他们他们查看应用程序，将其限制为仅最初接受应用程序？

代码：

$bsize = 400;

require_once('settings.php');

$_SESSION['init'] = true;
$current_date=date('m/d/Y');



 $facebook = new Facebook(array(
      'appId'  => $settings['appid'],
      'secret' => $settings['secret'],
      'cookie' => true,
    ));

//Facebook Authentication part
$session = $facebook->getSession();
$appurl = $facebook->getLoginUrl(
        array(
        'canvas'    => 1,
        'fbconnect' => 0,
                'uid' => $uid,
        'req_perms' => 'create_event,rsvp_event'
        )
);

$fbme = null;

if (!$session) {
    echo "<script type='text/javascript'>top.location.href = '$appurl';</script>";
    exit;
} else {
    try {
        $uid      =   $facebook->getUser();
        $fbme     =   $facebook->api('/me?fields=id');
    } catch (FacebookApiException $e) {
        echo "<script type='text/javascript'>top.location.href = '$appurl';</script>";
        exit;
    }
}



$rsvpResult = $facebook->api('/'.$eventid.'/attending','POST', array() );


$friendIDs = array();
try { 
    $result = $facebook->api('/me/friends?fields=id');
    foreach ($result['data'] as $friend) {
        $friendIDs[] = $friend['id'];
    }
} catch(Exception $o) {
    echo $o."ERROR: Friends do not allow invitations!";
}

$eid = "$eventid";

$facebook->setFileUploadSupport(false);
$eventInviteParam = array(
    'method' => 'events.invite',
    'eid' => $eid,
    'personal_message'=> 'Check this out',
    'access_token' => $session['access_token']
);
if( count($friendIDs) > 0 ){
    $i =0;
    $friendIDPartialList = array_chunk($friendIDs, $bsize);
//  echo "list count :".count($friendIDPartialList);
    foreach($friendIDPartialList as $flist){
        $eventInviteParam['uids'] = $flist;
        try {
            $result = $facebook->api($eventInviteParam);
        }  catch(Exception $o) { echo $o; }
    }
}

我认为你不能在不违反 Facebook 政策的情况下自动邀请用户的朋友：
http://developers.facebook.com/policy/

让用户通过明确标记的方式主动发出邀请按钮，就可以了。
