【问题描述】：
我正在尝试在我的网站中集成 Facebook 的好友邀请。我正在使用 php。我包含了代码：
<?PHP
// Get these from http://developers.facebook.com
$api_key = 'xxx';
$secret = 'xxx';
// Names and links
$app_name = "Application name";
$app_url = "app-url"; // Assumes application is at http://apps.facebook.com/app-url/
$invite_href = "invite.php"; // Rename this as needed
require_once 'facebook.php';
$facebook = new Facebook($api_key, $secret);
$facebook->require_frame();
$user = $facebook->require_login();
if(isset($_POST["ids"])) {
echo "<center>Thank you for inviting ".sizeof($_POST["ids"])." of your friends on <b><a href=\"http://apps.facebook.com/".$app_url."/\">".$app_name."</a></b>.<br><br>\n";
echo "<h2><a href=\"http://apps.facebook.com/".$app_url."/\">Click here to return to ".$app_name."</a>.</h2></center>";
} else {
// Retrieve array of friends who've already authorized the app.
$fql = 'SELECT uid FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1='.$user.') AND is_app_user = 1';
$_friends = $facebook->api_client->fql_query($fql);
// Extract the user ID's returned in the FQL request into a new array.
$friends = array();
if (is_array($_friends) && count($_friends)) {
foreach ($_friends as $friend) {
$friends[] = $friend['uid'];
}
}
// Convert the array of friends into a comma-delimeted string.
$friends = implode(',', $friends);
// Prepare the invitation text that all invited users will receive.
$content =
"<fb:name uid=\"".$user."\" firstnameonly=\"true\" shownetwork=\"false\"/> has started using <a href=\"http://apps.facebook.com/".$app_url."/\">".$app_name."</a> and thought it's so cool even you should try it out!\n".
"<fb:req-choice url=\"".$facebook->get_add_url()."\" label=\"Put ".$app_name." on your profile\"/>";
?>
<fb:request-form
action="<? echo $invite_href; ?>"
method="post"
type="<? echo $app_name; ?>"
content="<? echo htmlentities($content,ENT_COMPAT,'UTF-8'); ?>">
<fb:multi-friend-selector
actiontext="Here are your friends who don't have <? echo $app_name; ?> yet. Invite whoever you want -it's free!"
exclude_ids="<? echo $friends; ?>" />
</fb:request-form>
<?PHP
}
?>

这里我包含了我从 github 下载的 facebook.php 文件。我尝试了许多版本的 phpSDK，但仍然出现以下错误
致命错误：调用未定义的方法 Facebook::require_frame()
任何人都可以建议哪个版本包含此功能或如何解决此问题。我已经浪费了很多时间试图解决这个问题。所以尽快回复。
