I have a problem in my code, when i press create event nothing happens, here’s the code in php:
<?php
$app_id = "xxxxxxxxxxxxxxxx";
$app_secret = "xxxxxxxxxxxxxxxx";
$my_url = "xxxxxxxxxxxxxxxxx"; // mainly this should be the same URL to THIS page
$code = $_REQUEST["code"];
if(empty($code)) {
$auth_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url)
. "&scope=create_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
. "&grant_type=client_credentials";
$access_token = file_get_contents($token_url);
if( !empty($_POST) && (empty($_POST['name']) || empty($_POST['start_time']) || empty($_POST['end_time'])) ) {
$msg = "Please check your inputs!";
} elseif(!empty($_POST)) {
$url = "https://graph.facebook.com/me/events?" . $access_token;
$params = array();
// Prepare Event fields
foreach($_POST as $key=>$value)
if(strlen($value))
$params[$key] = $value;
// Check if we have an image
if( isset($_FILES) && !empty($_FILES['picture']['name']) ) {
$uploaddir = './upload/';
$uploadfile = $uploaddir . basename($_FILES['picture']['name']);
if (move_uploaded_file($_FILES['picture']['tmp_name'], $uploadfile)) {
$params['picture'] = "@" . realpath($uploadfile);
}
}
// Start the Graph API call
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
/*
Next option is only used for
user from a local (WAMP)
machine. This should be removed
when used on a live server!

*/
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
$result = curl_exec($ch);
$decoded = json_decode($result, true);
curl_close($ch);
if(is_array($decoded) && isset($decoded['id'])) {
// Event created successfully, now we can
// a) save event id to DB AND/OR
// b) show success message AND/OR
// c) optionally, delete image from our server (if any)
$msg = "Event created successfully: {$decoded['id']}";
}
}

Nothing happens if the token is not returned. This is the case when
file_get_contentsis not working properly. To make sure that this function treats url as a file, you need to make sure that it is configured under php.ini as follows “allow_url_fopen = 1”
