cURL または を使用してその URL をクエリする必要があります。これfile_get_contents()
は私のチュートリアルの例です。
<?php
$app_id = "APP_ID";
$app_secret = "APP_SECRET";
$my_url = "REDIRECT_URI";
$event_id = "EVENT_ID";
$rsvp_status = "";
$code = $_REQUEST["code"];
if(empty($code)) {
$auth_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&scope=rsvp_event";
echo("<script>top.location.href='" . $auth_url . "'</script>");
}
$token_url = "https://graph.facebook.com/oauth/access_token?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret
. "&code=" . $code;
$access_token = file_get_contents($token_url);
if( isset($_POST['rsvp']) ) {
// Form submitted, call the Graph API to RSVP to the event
$event_rsvp = "https://graph.facebook.com/$event_id/{$_POST['rsvp']}?method=post&" . $access_token;
$rsvped = json_decode(file_get_contents($event_rsvp));
if($rsvped) {
$msg = "Your RSVP status is now <strong>{$_POST['rsvp']}</strong>";
$rsvp_status = $_POST['rsvp'];
}
}
if( !$rsvp_status ) {
$query = "SELECT rsvp_status FROM event_member WHERE eid=$event_id AND uid=me()";
$fql_url = "https://api.facebook.com/method/fql.query?"
. "query=" . urlencode($query)
. "&format=json"
. "&" . $access_token;
$fql_resp = json_decode(file_get_contents($fql_url));
$rsvp_status = $fql_resp[0]->rsvp_status;
}
?>

あなたは見ているべきです:
if( isset($_POST['rsvp']) ) {
// Form submitted, call the Graph API to RSVP to the event
$event_rsvp = "https://graph.facebook.com/$event_id/{$_POST['rsvp']}?method=post&" . $access_token;
$rsvped = json_decode(file_get_contents($event_rsvp));
if($rsvped) {
$msg = "Your RSVP status is now <strong>{$_POST['rsvp']}</strong>";
$rsvp_status = $_POST['rsvp'];
}
}
