Facebook Error: An error has occurred with the application. Please try again later
My code that was working until yesterday suddenly started throwing errors. I don't know what changed everything. It is also based on code from Facebook Parties Authentication . Also I have mentioned other posts with a similar title, but tried what they mention and no luck.
Here is the code
<?php
$app_id = "my app id";
$app_secret = "my app secret";
$my_url = "http://apps.facebook.com/myappnamespace";
// Tried https in my_url // Also tried to use direct app path with both http and https and doesn't work. session_start (); $ code = $ _REQUEST ["code"];
if(empty($code)) {
$_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection
$dialog_url = "https://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
. $_SESSION['state'];
echo("<script> top.location.href='" . $dialog_url . "'</script>");
}
if($_REQUEST['state'] == $_SESSION['state']) {
$token_url = "https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret . "&code=" . $code;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$graph_url = "https://graph.facebook.com/me?access_token="
. $params['access_token'];
$user = json_decode(file_get_contents($graph_url));
echo("Hello " . $user->name);
}
else {
echo("The state does not match. You may be a victim of CSRF.");
}
?>
