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事件，但是它会自动邀请所有朋友，有没有一种方法可以限制邀请的朋友数量，而不是每次都邀请他们他们查看了该应用程序，将其限制为仅接受该应用程序？

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; }
    }
}

我认为您不能在不违反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按钮主动发出邀请，这样您就可以了。
