Facebook PHP SDK: how to display login dialog automatically?

Question

My code cannot display the permission dialog when a user connect to my Facebook application. Instead of the login page, I got a 404 error. My code: require 'src/facebook.php'; require './config.php'; $facebook = new Facebook(array( 'appId' => $fb_app_id, 'secret' => $fb_secret, 'cookie' => true, )); $userData = null; $user = $facebook->getUser(); if ($user) { try { $userData = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); $user = null; } } else { $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'publish_stream', )); }

<?php if ($user): ?> ">Logout <?php else: ?> ">Login with Facebook <?php endif ?>

I have also tried to put directly an personalized URL (like bellow) and I got the same 404 error. $loginUrl = "http://www.facebook.com/dialog/oauth?client_id=".$fb_app_id."&redirect_uri=".$fb_app_url."&scope=publish_stream"; UPDATE 1: Otherwise when I try to Login directly through the server (from http://mydomain/application/index.php), I got a redirection to Facebook website to the URL below and got this error message: https://www.facebook.com/dialog/oauth?client_id=xxxxxxxxxxxxxx&redirect_uri=http://apps.facebook.com/myapplication&state=f8cd945d8a9aefcd0b439fecd8515a68&canvas=1&fbconnect=0&scope=publish_stream UPDATE 2: Here my application configuration: And the message I got when I try to access directly from the app link: apps.facebook.com/myapplication/ without be logged I would appreciate any help.

Answer 1

The status_update permission you are using in the scope for the loginUrl is not a valid permission. Take a look at the docs. That could be your problem. Also remember, that if a user has already authorized your app, they will not see the permission dialog again on subsequent logins. They will only be taken through the facebook login procedure. EDIT: Take a look at the image I've attached, facebook will on redirect to the url you specify in the site url field in app settings:
